      For Next Time

    • Keep your traffic light LEDs wired to Pins 4,5,6
    • Wire a momentary switch with Pull Down Resistor to Pin 3
    • Wire a potentiometer to Pin A0

    
    

    Save your traffic light sketch as Switch and Potentiometer
    
    Add code so that:
    1) with the switch not pressed the Green LED stays on.
    2) pressing the switch switches the signal to yellow for 3 seconds, then Red for 10 seconds.
    3) The Potentiometer adjusts the brightness of the Green LED
