This nifty Arduino project appears to use one ultrasonic sensor and one servo to keep a ball centered on those rails. Elegantly simple form factor! Should be doable with a Picaxe 08M2, IMHO. Looks like a great demonstrator project for PID loops. Maybe a good opportunity to finally use a VL53L0X laser sensor.

I will get to it trying this project at some point. Sure hope nobody beats me to it!

r/arduino - A project I’ve made by myself. Automatic Control System using arduino. The purpose is to balance the ball in the middle of the beam.
