How To Make An Automatic Night Light Circuit Electronicshacks How the night light circuit works: the automatic night light circuit operates based on the principle of the light dependent resistor (ldr) and transistor control. in darkness or low light conditions, the ldr’s resistance is high, preventing current from flowing through the base of the transistor. 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 circuit | how to make simple automatic night lamp with bc547 transister led night light project #electronic #ldr #ldr project #ldr nigh. For this circuit, though, we will only be connecting to 5 of the pins of the lm741. as most ics need power, we must power the chip. therefore, we must connect positive voltage to the v terminal of the lm741 and connect either negative voltage to the v terminal or connect it to ground. An automatic usb night light circuit can be built using a bd139 transistor, an ldr, or a 3.3k resistor. the circuit is designed to turn on a light automatically when the ambient light level falls below a certain threshold. this can be a useful feature in situations where you need a night light in a dark room. the bd139 transistor is used in the.

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 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.
