Let’s create a small level with a matrix display
The low cost of sensors and components allows us to build small gadgets and tools that were unthinkable just a few years ago. In this project, a “bubble” level has been created, which is a tool used to determine if a surface is perfectly level. The level was constructed using an accelerometer and an…
