Electro-Magnet Loop with hall effect sensor (coil gun theory)

Help & Support Robot Parts

Hi there,

I am in need of help, I have a power supply 7.2V 3000mAh, arduino uno, 26 swg enameled wire and a hall effect sensor. The loop has two electro-coils at opposite ends to accelerate ball bearings around the loop with the velocity being measured by the hall effect sensor. I want to be able to control the acceleration of the balls and direction of travel and stopping. Can you explain step by step how I would build this circuit and what I would need?

Thank you for any help,

Evan Little

Hi @evanlittle !

I’ve found this step by step on how to make a coil gun with Arduino: https://www.instructables.com/Make-Your-Own-Coilgun/

I hope it will help you a little.
