2nd. Version

Photocell with Supply Voltage No Transformer.

Votaje photocell with DC source.

This is the 2nd circuit. Photocell version created with a LM741 operational amplifier, used the op-amp as a voltage comparator with a reference voltage at pin # 3 which can be regulated with the potentiometer 5K ohms, and pin # 2, the LDR is a resistance that varies depending on the intensity of light, to turn the focus Moc use a 3021 which is an optocoupler which contains an internal diac and a triac 136, BT 3A, which can light a bulb that does not exceed 360Watts power in 110 V AC also use a transformerless voltage source which provides sufficient current needed by the IC to operate.
