Digital Input – Button
Digital Input – Troubleshooter
Analog Input – Potentiometer
My code doesn’t work.. I tried adding and changing the ‘else’ and ‘if’ commands, but that didn’t work either.
const int buttonPin1 = 2;
const int buttonPin2 = 3;
const int ledPin = 13;
int buttonState = 0;
void setup() {
pinMode(ledPin, OUTPUT);
pinMode(buttonPin1, INPUT);
pinMode(buttonPin2, INPUT);
}
void loop() {
buttonState = digitalRead(buttonPin1);
if (buttonState == HIGH);
digitalWrite(ledPin, HIGH);
else
digitalWrite(ledPin, LOW);
}
void loop() {
buttonState = digitalRead(buttonPin2);
if (buttonState == HIGH);
digitalWrite(ledPin, LOW);
else
digitalWrite(ledPin, HIGH);
}
}
