/* Use a button to toggle between LED lights */ int pressCount = 0; //Create a variable called 'pressCount' that is an integer (whole number) and starting value of 0 void setup() { pinMode(4,INPUT_PULLUP); //button pinMode(8,OUTPUT); //LED pinMode(12,OUTPUT); //LED } void loop() { if(digitalRead(4)==LOW){ //if button 4 is pressed pressCount++; //increase the value of pressCount by 1 delay(250); //delay gives you time to release the button before a press is counted twice } if(pressCount==1){ digitalWrite(8,HIGH); //turn on LED 8 digitalWrite(12,LOW); //turn off LED 12 } else{ //if pressCount is any value other than 1 digitalWrite(12,HIGH); //turn on LED 12 digitalWrite(8,LOW); //turn off LED 8 pressCount = 0; //reset the pressCount variable to 0 } } // (c) 2023 Let's Start Coding.
