Need to go from 12v to 5v, back to 12v Answered
I have a remote controlled submersible craft and the controller that came with it is incredible clunky. It has 3 switches that each control a motor and you almost need 3 hands to effectively drive the thing. What I want to do is take the 3 switches out and use 2 joy sticks instead – like this schematic I drew up.
My problem is that the power coming from the terminals for the original switches is 12v 7Ah, and the joysticks I have are rated for 5v. I need to step down from 12v at the switch terminals from the board to 5v for the joy stick, then from 5v at the joystick back to 12v so I can run power to the motors. Anyone have any ideas?
