How To Make Automatic Night Lamp Circuit Using Bc547 Transistor Youtube How to make automatic night lamp circuit using bc547 transistorrequired components: 1) bc547 transistor2) ldr 3) 10k resistor4) 1k resistor 5) blue led ️ bu. So, in this tutorial, we are going to go through a step by step procedure on how to make an automatic night light sensor using bc547 transistors. the main component of this circuit is an ldr or a light dependent resistor. an ldr is basically a photocell that works on the principle of photoconductivity. this passive component is basically a. How the night light circuit works. the photoresistor and the 100 kΩ resistor make up a voltage divider. when there is a lot of light, the photoresistor will have low resistance, which means the voltage divider gives a low output voltage. so the transistor is off and cuts off the current to the led. which means no light. Automatic night light: in our busy life, many of us forget to switch off the light morning. by using this simple circuit, the light will "automatically switch on" in night and "automatically switch off" in morning.

Automatic night light: in our busy life, many of us forget to switch off the light morning. by using this simple circuit, the light will "automatically switch on" in night and "automatically switch off" in morning. How the entire circuit works. the proposed transformerless automatic day night led lamp circuit may be understood through the following points: the input 220 v mains suply is applied across the 10 ohm resistor and the other neutral point. the 10 ohms resistor helps to cancel out the initial surge or the voltage rush that might otherwise be. Automatic night lamp working animation. you can choose a voltage between 3 to 32v for powering this circuit depending of the relay coil voltage. i choose 12v since 12v relays are very common in the market. note : you should keep the ldr in such a way that light from lamp l1 (connected to this circuit) will not fall on it.
