Another good time learning some more about Arduino. I got both the lessons to function and came up with some modifications to get a two button switch going. It’s a great break from some of the other work I have to do! Check out what I did here.
The code I used for my solution to the double button switch is as follows:
// set pin numbers: const int buttonPin1 = 2;// the number of the pushbutton pin const int buttonPin2 = 3; const int ledPin = 13; // the number of the LED pin // variables will change: int buttonState1 = 0;// variable for reading the pushbutton status int buttonState2 = 1; void setup() { // initialize the LED pin as an output: pinMode(ledPin, OUTPUT); // initialize the pushbutton pin as an input: pinMode(buttonPin1, INPUT); pinMode(buttonPin2, INPUT); } void loop() { // read the state of the pushbutton value: buttonState1 = digitalRead(buttonPin1); buttonState2 = digitalRead(buttonPin2); // check if the pushbutton is pressed. // if it is, the buttonState is HIGH: if (buttonState1 == LOW) { // turn LED on: digitalWrite(ledPin, HIGH); } if (buttonState2 == LOW) { // turn LED off: digitalWrite(ledPin, LOW); } }
