Hi, Please have a look at the circuit at:
The circuit it to turn on or off a AC bulb by a microcontroller. My question is, can we somehow safely add a manual override switch near the bulb, so that even if the microprocessor is not working, we can turn the switch on/off manually? If yes, how will the circuit then look like? Sorry if this is a simple question as I am just starting in electronics and electrical circuits.
