In this project we will have a closer look at accelerometer ICs and find out how we can use them with an Arduino. Afterwards we will combine such an IC with a couple of complementary components and a 3D printed enclosure in order to create a digital spirit level. Let's get started!

Step 1: Watch the Video!

The video gives you all the information you need to create your own digital spirit level. During the next steps though I will present you some additional information.

Step 2: Order Your Components!
