From Tobias Kuhn:
Not quite your usual ball and plate with PID control. The sole purpose of this Arduino project is to keep a ball bouncing for as long as possible.
The thing uses:
– 2 Arduinos (Arduino Uno & Arduino Nano)
– 4 Nema17 Stepping motors
– 4 elctrec mics
I made the data visualization on the left with Unity. It shows the data points gathered by the 4 mics. The plate is driven by 4 steppers.
