How to Build a Heater with Arduino – Part 1

This tutorial will explain how to build a portable heating device with Arduino. If you’re an amateur astronomer, this can be the perfect way to prevent the formation of dew on your mirrors and lenses. In my specific case, I’ve built one of those mini heaters to warm up a formicarium. Whether it’s for your feet or for your cold-blooded pets, building a heater is easy and cheap.

The second part of this tutorial (How to Build a Heater with Arduino – Part 2) will explain how to use a temperature sensor to maintain a desired temperature. Continue reading

Everything You Need to Know About LEDs

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:

LEDs are perfect for creative projects, and they can be also be used to create entire games, such as the mesmerising Line Wobbler.

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