How To Make Simple Automatic Night Lamp With Bc547 Transistor Led Night If you have any question about this project, please feel free to leave a comment below , if you like this video please like & share & subscribe my channel fo. 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.
Simple Automatic Night Light Using Ldr Bc547 Transistor Youtube Hi guys this in this video i have shown how you can make a very simple and easy automatic night lamp circuit using ldr and a bc547 transistor.it only require. 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. #led #ldrsensor #emergencylight #emergencylamp #emergencylightkaisebanaye automatic night light circuitldr darkness sensor circuithow to make automatic night. 1. bread board 2. ldr (light dependent resistor) 3. relay 6 volt dc (spdt) 4. diode 1n4001 5. resistor 1k and 330r 6. transistor bc547 (2) 7. bulb.

Nigh lamp circuit working. now we will discuss the working of the circuit, here we have used a 5v dc supply (arduino’s 5v) and connected a 10k ohm resistor and an ldr in a voltage divider circuit. the voltage which can be taken across the resistor or the ldr and fed into the analog pin of the arduino, pin a3 in this case. 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 potentially harmful to the further.
