This device is a digital level, protractor, ruler, and roll measure all in one

Arduino TeamApril 30th, 2019

When you need to take a measurement for a project, there are a wide variety of off-the-shelf devices available. Or you can make one exactly to your specs, like Patrick Panikulam did with his “Digital Multi-Function Measuring Tool.”

This Arduino-based gadget employs an MPU-6050 accelerometer / gyroscope that lets it act as a 2D level, as well as a digital protractor after zeroing it at a starting point. The unit also features straight-line measurement capabilities via an IR distance sensor, and even has an encoder/wheel that can measure rolled distance when that isn’t convenient.

Three touch buttons are used for control, which allow Panikulam to navigate through various modes and units without disturbing the position of the multi-tool while at work.

Power is provided by a rechargeable battery, and the entire thing is packaged in a nice wood and carbon fiber facade. Check out the demo video below, or you can find more details on how to build your own here.
