In this video we will take a look at building a light that changes colour based on the temperature in the room.

This is actually quite a nice beginner project for Arduino as the circuitry is fairly simple and so is the code, but it has a nice practical use case.

I'll also dive a little bit deeper into why I picked certain sensors and give some advice on how to go about doing a project like this. I hope you enjoy it!
