hye there...
Im doing a project title 'light sensor based on-off controller for AC load'. For enhancement, i need to create another sensor that later will be combine to an OR gate. My problem now is, i don't know what value of silicon diode that i can use to create an OR gate. I hope anyone...
this is the circuit that im doing but i added 1k resistor n LED after the relay.

The problem nw is, when there's no light on the LDR, the LED will turn ON but once i put a light on LDR, the LED is OFF. I tried...
hye..im creating a light sensor. My question is, what is the value of the LDR that i have to used for a 12v supply and how to know what value that i should use?
hye, im doing a project title ' Light Sensor Base On-Off Controller For AC-Load'. Can someone tell me what are the components needed for this circuit?:?:
