Step 3: PROGRAMMING CODE

int buzzer = 8; int button = 2; int LED = 3; int buttonState = 0; void setup() { // put your setup code here, to run once: pinMode (buzzer, OUTPUT); pinMode (button, INPUT); pinMode (LED,OUTPUT); } void loop() { // put your main code here, to run repeatedly: buttonState = digitalRead(button); if (buttonState == HIGH) { tone (8,400,800); digitalWrite(LED,HIGH); delay (1000); } else { noTone (8); digitalWrite(LED,LOW); } }
