I want to turn the hardwired power seat controls into a microcontroller controlled circuit using an analog joystick (like what is on a game controller).
Each seat has 3 motors and 3 switches, and each switch is in a normally open position, and when moved one way will send one polarity to it's motor, and when moved the other direction it will reverse polarity to the same motor.
If I use relays then I would need 4 relays per motor (h-bridge), and with 6 motors that would mean 24 relays!!!
Does anyone have any other thoughts on the best way control these motors from a microcontroller? I have thought about using mosfets but the only thing I would gain over relays is size because the mosfets required to pass that much current would cost quite a bit.
