I make the light delay longer, it is because if it blinks too fast, the car will not be able to cross the road.

Connecting the LEDs

You need 7 wires and 3 LEDs.

First, plug a wire from 13 on the Arduino to the top row on the breadboard. Next, plug a wire from 12 on the Arduino to the top row on the breadboard. Then plug a wire from 11 on the Arduino to the top row on the breadboard. Connect a wire going from the negative rail to the right of the other wires on the breadboard. Lastly, put the longer leg of the Led (+) under the wire that goes to the Arduino. The shorter leg of the LED goes under the port that connects to the negative rail.

Make It Look Like a Traffic Light

I use a bag to cover the breadboard. Then, cut 3 holes to let the light more shining.
