Many game developers are easily scared by electronics. Even if Arduino has shifted most of the workload on its software side, there are applications which still need a good knowledge of circuitry.  This post will teach how to use LEDs, from the most basic model to the most advanced one:

• Part 0. Theory

• Part 1. Basic LED

• Part 2. RGB LED

• Part 3. Neopixel strip

• Conclusion

This post belongs to a series of tutorials aiming to teach game developers how to build their own alternative game controllers:

• How to integrate Arduino with Unity

• How to build a distance sensor

• How to hack any IR remote controller
