IR-Remote Color Guessing Game

In this instructable, I will show you how to control an RGB led using an IR-remote, and make a fun game out of it!

Step 1: Parts Needed

The parts you will need for this project are:

- arduino one
- RGB Led
- IR-Sensor

(led count depends on the game, the amount of lives or )
- 2 green leds
- 1 yellow led
- 1 orange led
- 3 red leds

Step 2: Code

Step 3: Build

You obviously want a nice build for this project. this part is pretty open to interpretation, but there are some things to keep in mind with this:

- keep the front panel thin, so you can still stick your leds through it and the IR-receiver still works

- keep enough space in the build for the arduino and a solder board

- make sure there is a hole in the back for the power of the arduino

I've added a rough scheme for the wiring.

Good luck, and have fun!

    Fun project. This is a great tutorial for teaching the basics of Arduino inputs and outputs.
