In this Arduino tutorial I will show you how to turn an LED on and off with a push button. In fact, we’ll do 2 slightly different applications. First, we will power on the LED when the button is pressed, and power off the LED when the button is not pressed. And then we’ll mo...
void loop() { /* read the state of the pushbutton value:*/ buttonState = digitalRead(buttonPin); /* check if the pushbutton is pressed. If it is, the buttonState is HIGH:*/ if (buttonState == HIGH) { /* turn LED on:*/ digitalWrite(ledPin, HIGH); } else { /* turn LED of...
