We are using a hamster wheel alongside our own designs of a ramp and a funnel to orientate the pipette tips in the correct orientation. We are controlling the wheel and the refeeders in tandem using 3 stepper motors connected to an Arduino MEGA 2560.
The wheel is connected to the same Arduino MEGA 2560 board as the refeeders.
Arduino MEGA 2560 board that controls both the rotation of the wheel and the refeeders.
