Project Copy the starter code and implement the circuit in Tinkercad. Modify the code so that only one LED is on at a time, and instead of blinking the light moves from left to right or right to left. Use the the left button to switch direction. Make sure that holding a button down diables reacting it until the button is released. Implement your circuit and program using the real Arduino circuit.
