[TUTORIAL] How to build a distance sensor with Arduino (Patreon)

This tutorial will show how to build an inexpensive distance sensor with Arduino, using only infrared diodes. With less than £10 you can make 20+ of them.

List of components:

• Arduino Uno (£18.95);
• IR photodiode receiver (£4.11 / 50pcs);
• IR emitter (£3.08 / 50 pcs);
• Resistors: 18Ω, 39Ω.

The sensor created in this tutorial can be easily integrated with Unity. Check here for more information.

This post is part of a longer series of tutorials about alternative game controllers. If you are going to create an alternative game controller yourself, you should definitely look into ALT.CTRL.GDC. It’s one of the most fresh and intriguing exhibitions at GDC San Francisco, and is all dedicated to innovative ways to interact with games.
