    Default pic window

    looks like the main reason for PIC is to check current to disconnect relay when window is all up or down ??

    The reasons for using PIC :
    -small circuit
    -two different function (up and down) with two possibilities (long/short press)
    -detecting over-current
    -huge support from this forum (thanks again !)
    -personal ambition !

    Default circuit

    you may want to add free wheeling diode across each relay coil, common practice because of the voltage spike generated by relay coil when released (switched off)
