Power Windows PCB

Arduino project to add power window control to 'old' car

Electronic control for vehicle originally with manual window winders, and motorised actuators retrofitted.

Proposed schema:
Mount 2 switches on centre console and arduino and 4 relay board and current sense boards nearby and run 1 pair wires carrying drive current to each door.

Momentarially operating a Left or Right switch (or both) should drive in the correct direction until either.
The winding is
1. Halted by user ie momentary action of (either up or down) switch
2. Window reaches maximum travel and halts due to measured current being above set point. ie the electric motor stalls (I'm working on approx 5-10A, will need to test)
3. Timed-out after a fixed period. (For circumstance where window is slow but not tripping overcurrent)

Holding switch operated should
1. Not block operation of other user
2. Operate window winding in desired direction until either
  a. Timeout occurs
  b. User releases switch
  c. Current sense detects end of travel
