Pull-up vs pull-down switch interface Pull up switch circuit Pull down switch circuit

Connecting a switch to an I/O pin LED connected same as before (pin 8 in this example) Add the switch circuit (pin 4 in this example) //sample switch code const int buttonPin = 4; const int ledPin =  8; int buttonState = 0; void setup() { pinMode(ledPin, OUTPUT); pinMode(buttonPin, INPUT); } void loop() {   buttonState = digitalRead(buttonPin);   if (buttonState == HIGH) {     digitalWrite(ledPin, HIGH); } else {     digitalWrite(ledPin, LOW);

Lab assignment There are only 29 kits which means each group needs to have 3.2 members per team Get the onboard LED to light when the switch is held down Get the LED to toggle with the switch – push on -> push off -> etc. Mouse button – single click -> red LED, double click -> green LED, long press -> all off. Play
