How To Make Transformer Less Automatic ON/OFF Light Switch Circuit..Simple Automatic ON/OFF Switch..

Friends in this video I will show you How To Make Transformer Less Automatic ON/OFF Light Switch Circuit...Simple Transformer Less Automatic ON/OFF Light Switch..Friends it is a transformer less power supply circuit,,in this circuit we will not use any transformer but we can easily operate this circuit by 220 volt..Friends the circuit diagram of the automatic on/off light switch circuit is in the video please see the circuit diagram..Friends you can connect any electric light with the circuit...Friends we will use ldr in this circuit to sense the light..if you want more sensitivity then you will have to connect two ldrs with the circuit instead of one ldr..Friends we will use a 12 volt relay in this circuit to on/off the light..Friends when the light will fall on the ldr the relay will remain off and the connected light will also remain off but when the light will not fall on the ldr the relay will be on and the connected light will also on..That mean's the circuit will remain off in the light and will be on in darkness..Friends in this way the circuit will work..So friends if you want to know how to make a transformer less automatic on/off light switch circuit at home then watch the video and follow my instruction...Thanks..
