Step 1: Gather Materials

- An Arduino UNO

- A small breadboard

- An IR Obstacle Avoidance Module

- Four (4) LEDs

- Four resistors (two 220ohm and two 330ohm)

- One extra LED and resistor

- Jumper wires

- Breadboard

Step 2: Place the Things in Place

You can use a Male to Female Jumper wire to make the power signal light away from the board, and indicate the power on better.

You can use any kind of box to make it look better.

here is the code! (led power light won't need a line because it will light on when there is power)
