Combining a spirit level and range measurer into a single device

This device by Dejan Nedelkovski of How To Mechatronics implements both an ultrasonic sensor for range measurement and an accelerometer for measuring angles. While you’ve likely seen these implemented separately in other projects, combining them saves space, and allows the Arduino Nano onboard to use the two readings together to calculate a square area automatically.

Graduate students Ben Wiener and Philip Zucker have been working on a classic controls problem for quite some time called an “inverted pendulum.” This type of device balances a stick on an axis, and in this implementation, a motor pulls the axis assembly that the pendulum—a paint stirrer—is sitting on to keep it stable.
