3 LEDs (recommended colors: green, yellow, red)
3 110 ohm resistors
1 Arduino Leonardo
1 x USB cable
1 x breadboard
Step 1: Setting Up the LED
Connecting the first wire to GND then the second wire to ~6 , the third one to 8, the fourth one to ~10. After connecting all the wires connect LED lights red yellow and green and three 220-ohm resistors. You can connect wires at different place unless connect at the right places.
Step 2: Uploading the Code
After setting up the LED lights, we need to do the software.

Step 3: Decorating It Like a Real Traffic Light
Make three LED light like a real traffic light on the road.
Step 4: Work
Connect with computer.
