Do you have an application where you want multiple buttons for different user inputs?  Maybe you have a timer and you want one button for minutes and another for hours. But there is a problem – you only have room for one button! In this tutorial, we are going to use Arduino to explore how to make one button have the functionality of two or more. Click here to join our 12-part HD Video Course.   You Will Need: (1) Momentary push button (5) Jumper wires (1) Solderless breadboard (2) LEDs (2) 220 Ohm resistors Set Up The Circuit: To demonstrate making one button have the functionality of two or more, we will set up a simple circuit with 2 LEDs and a button.  Based on how we press the button, different LEDs will illuminate. Follow the instructions and schematic below to get the circuit set up before we dive into the mechanics of the Arduino code. Using a jumper wire, connect any GND pin from the Arduino, to the ground rail on your breadboard. Place an LED on your breadboard, make sure to note which way the long leg is facing. Using a jumper wire, connect pin 13 from your Arduino to the breadboard in the same channel where you have the long leg of the LED attached. Now connect one side of the 220 Ohm resistor to the short leg of the LED, and connect the other leg to the ground rail on the breadboard.  The orientation of the resistor doesn’t matter. Repeat this using pin 12, and another LED and resistor. Finally, place your push button on the breadboard.  Depending on the style of your pushbutton, they often fit well straddling the long trench that goes through the breadboard. Connect a jumper wire from one side of the button to pin 2 on the Arduino. Connect a jumper wire from the other side of the button to the ground rail on the breadboard. That's it for the circuit setup.  Now, when you press the push button (which will electrically connect both sides of the button), pin 2 to will have ground voltage applied.  We will use this ground voltage input to trigger our different functions. Examine the Sketch: There are couple ways to implement the multi-function button press using Arduino. One way is to have the number of presses determine the output.  For example, a single click might highlight the “hour” field of an LCD timer and a double click might highlight the “minute” field of the display. Another way that we can implement multiple functions with one button is for the user to hold down the button for different lengths of time with the length of the hold determining the output. For example, if the user holds the button for half a second and releases, something happens.  If she holds it for 2 seconds, something different happens. This latter method of using button hold length time to determine separate functions is the strategy we will learn here. Before I go any further though, I would like to thank Steve for creating the base Arduino code that we will be using.  Steve is a member of the Premium Arduino course (a couple of months ago, he was new to Arduino). While creating a home automation project, he was in need of using a single button to do multiple things, and came up with a very simple way to make it happen.  Thanks Steve! Here is the complete sketch, I recommend looking it over first, and then we will discuss it piece by piece below. /*Using a Single Button, create mutliple options based on how long the button is pressed The circuit: * LED attached from pin 13 to ground through a 220 ohm resistor * LED attached from pin 12 to ground through a 220 ohm resistor * one side of momentary pushbutton attached to pin 2 * other side of momentary pushbutton attached to Ground * Note 1: on most Arduinos there is already an LED on the board attached to pin 13. * Note 2: In this circuit, when the button is pressed, Ground Voltage is what will be applied.

Declare and Initialize Variables: After the comments, we start initializing and declaring variables.  Since, we are going to be tracking time, we need to have a variable to record the length of time a button is being held.  We do that with the pressLength_milliSeconds variable: //We need to track how long the momentary pushbutton is held in order to execute different commands //This value will be recorded in seconds float pressLength_Seconds = 0; Now, you might think that the variable name is really long and annoying.  And I wouldn’t particularly argue with you – I mean, why would I include milliSeconds in the name of the variable? The reason I do this is because I think including the unit of measurement in the variable name is helpful when other people are trying to read your code.  Writing code that other people can read is not only good for other people, but also future versions of yourself who forget what the heck you were thinking when you wrote the code! [End Rant] The next thing we need to set up are the parameters for when options will get executed.  In this example, I have two variables for two options: // Define the *minimum* length of time, in milli-seconds, that the button must be pressed for a particular option to occur int optionOne_milliSeconds = 100; int optionTwo_milliSeconds = 2000; Each option is defined by the number of milliseconds that the button must be held for that specific option to get executed.  In order to get my first option to happen, I have to hold the button for at least 100 milliseconds which is pretty much a short tap on the button. If I want the second option to happen, then I have to hold the button for at least 2000 milliseconds aka 2 seconds. If you wanted more options, you would add more variables here with their corresponding hold times. Our final initializations will be to specify pin numbers for our button and LEDs. //The Pin your button is attached to int buttonPin = 2; //Pin your LEDs are attached to int ledPin_Option_1 = 13; int ledPin_Option_2 = 12; Setup() the Sketch: The setup() for this sketch is pretty straight forward (if it’s not straight forward to you, make sure to check out our free 12-part Arduino Course, after which this setup will be very familiar to you). We want to make sure that the pin our push button is connected to is set as an INPUT_PULLUP: // Initialize the pushbutton pin as an input pullup // Keep in mind, when pin 2 has ground voltage applied, we know the button is being pressed pinMode(buttonPin, INPUT_PULLUP); We do this to make sure that the button pin is not floating (if you are wondering what the heck that means, you can read more on that here – but if you just roll with me until we get through this tutorial, you should be fine ). We also want to specify the pins that our LEDs are attached to as OUTPUTs, because we will be applying voltages to these pins in order to illuminate them: //set the LEDs pins as outputs pinMode(ledPin_Option_1, OUTPUT); pinMode(ledPin_Option_2, OUTPUT); Finally, it never hurts to start serial communications for debugging purposes. //Start serial communication - for debugging purposes only Serial.begin(9600); With setup() complete, now we can jump into the main loop of our sketch… The Main Loop(): We know we are going to have to measure the length of time the button is pressed, and then record it. To do this, we use a while statement whose condition requires the button pin to be in a LOW state (remember, when we push the button, pin 2 will have a ground voltage applied). //Record *roughly* the tenths of seconds the button in being held down while (digitalRead(buttonPin) == LOW ){ Once the button is pressed and held, the while statement starts executing.  The first thing we do in the while statement is to delay 100 milliseconds, and then record that into our time tracking variable: delay(100); //if you want more resolution, lower this number pressLength_milliSeconds = pressLength_milliSeconds + 100; Keep in mind the first time through the loop, pressLength_milliSeconds will be equal to 0, so we are just adding 100 to the variable. It can be handy to know how long the button has been pressed as you add options. To make this easy, we want to print the current value of the pressLength_milliSeconds variable to the serial monitor window: //display how long button is has been held Serial.print("ms = "); Serial.println(pressLength_milliSeconds); Let’s ignore the rest of the code for a second, and imagine what happens if we keep holding the button. The first time through the while loop, we add 100 milliseconds to the time tracking variable and we print that value to the serial port.  The next time through loop, we add another 100 milliseconds to the timer counter variable, and print this new value to the serial monitor. As long as the button is being held down, then we keep adding time to the pressLength_milliSeconds variable – this is the crux of the program. When we release the button, the while statement stops, because the condition is no longer met, and we stop adding time to pressLength_milliSeconds. So let’s pretend we held the button for three seconds, and then let go - what happens? Well, as we discussed, the while statement ends and the next line of code we encounter is an if statement. //Option 2 - Execute the second option if the button is held for the correct amount of time if (pressLength_milliSeconds >= optionTwo_milliSeconds){ digitalWrite(ledPin_Option_2, HIGH); } The condition of the if statement requires that the time we held the button be longer than or equal to the time we set for option number two. If you recall, option number two was set to occur with at least 2 seconds of button press time. Since we held the button for three seconds, this if statement will get executed. And all we do is write HIGH voltage to our “option 2” LED, making it illuminate. What if we had only held the button for one second – then what would happen? If this were case, then the first if statement condition would not have been met, but a subsequent else-if statement only requires the button hold time be 100 milliseconds or more – so the second else-if statement would get executed, which turns on the “option 1” LED. //option 1 - Execute the first option if the button is held for the correct amount of time else if(pressLength_milliSeconds >= optionOne_milliSeconds){ digitalWrite(ledPin_Option_1, HIGH); }//close if options Basically, if we hold the button a long time, the second option gets executed.  If we hold the button a short time, the first option gets executed. If we wanted to add more options, we add the longer hold options at the top, and the shorter hold options at the bottom. I wouldn’t try to squeeze too many options in a small span of time or it might drive the end user crazy trying figure out the timing. Nor would I try to add more than three options for a single button within a given context, or else you chance making your potential end user want to beat you up. To finish up the sketch, we reset our button press timing variable to zero.  This ensures that next time the button is pressed and held, we will start from time zero again. Try On Your Own Challenge: Add another option, which turns off both LEDs.  Try adding it before the first option (you will have to adjust the timing) and then after each option. How tight can you squeeze the option time together?  Experiment and determine what is a good rule of thumb. Download: PDF of this Arduino Tutorial

In order to understand why HaShem uses Moshe to point out the downfalls of the people, we must read what it says in verses 24-29 again carefully. I won’t quote it all here; I want you to read it for yourself. Allow me to use material from a previous commentary that I’ve written to explain it to you: Prior to coming to faith, the Torah served as a reminder of sin (Romans 7:7-12). This is not the only function of Torah, but it is a primary one. After coming into a relationship with HaShem, through His Son Yeshua (Jesus), the [person] underwent a change in relationship to the Torah. The Avrahamic Covenant became for him or her, a “promise of inheritance”. An “inheritance” of what? Of “eternal life”, through trusting faithfulness. It became their “proof of ownership” so-to-say. It still reminded him or her of their sin. However, because we now constitute the Righteousness of HaShem (2 Corinthians 5:17-21; Ephesians 2:1-10), we are now free to pursue following HaShem without the threat of death for disobedience! “For through the law I died to the law so that I might live for God.” What does he mean that he “died to the Law?” Is he dead to any responsibility to uphold and follow the injunctions of the Torah? Is he free to chart his own course apart from God’s objective instructions as outlined in the pages of the Five Books of Moshe? Allow me to pull a few comments from my Exegeting Galatians commentary: Comments: At first blush this verse seems to spell the end of any Torah relevance for the apostle. But a careful reading will reveal its true meaning. The verse starts out with the word “for” (Greek=gar) a conjunction indicating that it is linked to a previous argument. In this case, Paul’s “for” represents an answer to the “if” clause introduced in [Galatians 2] verse 17 ("If, while we seek to be justified in Christ, it becomes evident that we ourselves are sinners..."). The key to understanding verse 19 is in answering exactly how we as individuals in verse 17 come to be made aware that “we ourselves are sinners”). Prior to his salvation experience Sha'ul was blinded to his true condition: dead in trespasses and sin. However, now that the Spirit has taken up residence within him, via the sacrificial death of Yeshua, he can look back to how the Torah played a part in bringing him to this newfound revelation about himself. The Torah, working in concert with the Spirit of God, revealed sin for what it was: violation of God’s righteous standard. Thus, through the Torah—that is, through its proper function of revealing and condemning sin, the individual is brought to the goal of the Torah, namely the revelation of the Messiah himself. Once faced with the choice to remain in sin or be set free by the power of the Blood, Paul confesses that he “died” to his old self and was consequently made alive in the newness that is accredited to those who choose life! But Paul says that he died to Torah. What does he mean by such a statement? Are we to assume that in Yeshua Paul is now somehow dead to obedience to the Torah? May it never be! Simply put, he now realizes that his new life in the Spirit is a life to be lived without the fear of being condemned as a sinner by the very Torah he previously thought he was upholding! The Torah has a properly installed built-in function of sentencing sinners to become the object of HaShem’s punishment and ultimate rejection, a rejection that will result in death if the person never choose the Messiah of life. Paul is teaching the Galatians that his choice of Yeshua is to be understood as a death of self and the former life that Torah condemned in favor of a new life of serving God through the Spirit, a choice brought on by the revelation of Messiah found within the very pages of the Torah itself! Such freedom in Messiah does not liberate one from Torah, rather, such freedom liberates one to be able to walk into Torah as properly assisted and seen from God’s perspective!

Verse 19 - For through the law I died to the law so that I might live for God. Comments: At first blush this verse seems to spell the end of any Torah relevance for the apostle. But a careful reading will reveal its true meaning. The verse starts out with the word “for” (Greek=gavrv, gar) a conjunction indicating that it is linked to a previous argument. In this case, Paul’s “for” represents an answer to the “if” clause introduced in verse 17 ("If, while we seek to be justified in Christ, it becomes evident that we ourselves are sinners..."). The key to understanding verse 19 is in answering exactly how we as individuals in verse 17 come to be made aware that “we ourselves are sinners”). Prior to his salvation experience Sha'ul was blinded to his true condition: dead in trespasses and sin. However, now that the Spirit has taken up residence within him, via the sacrificial death of Yeshua, he can look back to how the Torah played a part in bringing him to this newfound revelation about himself. The Torah, working in concert with the Spirit of God, revealed sin for what it was: violation of God’s righteous standard. Thus, through the Torah—that is, through its proper function of revealing and condemning sin, the individual is brought to the goal of the Torah, namely the revelation of the Messiah himself. Once faced with the choice to remain in sin or be set free by the power of the Blood, Paul confesses that he “died” to his old self and was consequently made alive in the newness that is accredited to those who choose life! But Paul says that he died to Torah. What does he mean by such a statement? Are we to assume that in Yeshua Paul is now somehow dead to obedience to the Torah? May it never be!

Such freedom in Messiah does not liberate one from Torah, rather, such freedom liberates one to be able to walk into Torah as properly assisted and seen from God’s perspective! Verse 21 - I do not set aside the grace of God, for if righteousness could be gained through the law, Christ died for nothing!" Comments: Bringing his arguments of the previous verses, and indeed the chapter as we have it, to a close, Paul again reinforces the truth that the “righteousness of God” is attained for an individual at Christ’s expense and not through the rubrics of a man-made conversion ceremony (read here as “through the law”). The “law” in question is the Oral Tradition that only Isra'el can inherit blessings in the World to Come, a belief formerly held to by the apostle himself. To be sure, if being declared righteous (understood to be primarily forensic, but including behavioral as well) could be achieved via the flesh (that is, being born Jewish or converting to Judaism) then truly what need would there be for a Messiah to come and provide it later for anyone? Paul would have the reader to understand that such righteousness is altogether outside of human achievement and therefore must be procured by surrendering to the power of the Anointed One of God.
