Automatic Light Dimmer Circuit

This is an automatic light dimmer circuit. You do not need to dim the lights by yourself. It is so very convenient because we use the LDR to detect external light. To control the Triac and the brightness of the lamp next.

– Suppose low light so there is the voltage across the LDR many making the TRIAC a lot of work, the lamp so super bright. But sometimes the light is very high so a few voltages at Triac, then the lamp do not work or low bright.

-This circuit we used only an incandescent light bulbs size AC220V 50Hz at 5 watt because low power triac and basic circuit. You should not be touch the circuit. you may be to get electrocuted.
