In this project I will face a problem that I encountered quite a while ago. When using my cordless drill, then I can not always go completely straight (level) through the material. This also happens when I try to drill top down into the wood. Attaching mechanical spirit levels, was not an option for me. So in this video I used an accelerometer IC and a smart feedback system to create a way better digital (kind of) spirit level. Let's get started!
