bi stable 2 coil relais switch
-
I have no idea where to start, I have a bi stable relais with 2 coils 3v, I want to use it as a batt powered switch using one button. So push once A2 is High for 1 sec, push a second time A3 is high for 1 second. The latest status must be stored in case of a power failure. Does anyone have start code for this project? Most imporatant is how to store the last status of one of the coils.
