Light ON at night and light OFF in day all automatic! A single LDR and a BC547 transistor perform all these functions. This Smart Street Light Control Circuit is a easy and simple way to save energy and also there is no manual effort and no energy waste. Circuit Working: Parts List: Components Values Quantity […]
LED and Lamps
Temperature Controlled LED Circuit
This small Temperature Controlled LED Circuit can feel the heat! When we place near warm thing, it sense temperature and LED glow and it work very simple using one diode and one transistor only. No microcontroller, no sensor IC, just few parts and also we can build it easy at home and see how heat […]
LDR Based Dark Sensor Circuit
This small LDR Based Dark Sensor Circuit is very smart, as it can see light and dark using LDR. When there is light, everything stay quiet and when it becomes dark then LED start to glow and buzzer makes sound; also there is no need to touch anything it works by itself. In addition, it […]
Automatic Light Control Circuit using LDR and LM3909 IC
This Automatic Light Control Circuit using LDR and LM3909 IC is small and smart light sensor circuit which can feel light and dark like magic; also it uses few circuit parts like LDR, LM3909 IC, capacitor and an LED. When dark come, LED turns ON and when light come, LED goes OFF, which is perfect […]
Adjust LED Glow with Potentiometer Circuit
This project show how to Adjust LED Glow with Potentiometer Circuit, also we used diode, resistor, battery and potentiometer. By turning potentiometer we can change voltage and LED brightness and its a very easy to make project and works with 9V battery. Circuit Working: Parts List: Components Values Quantity Resistors 470Ω 1/4 watt 1 Potentiometer […]
Arduino Based Control LED Light Circuit with Potentiometer
Want to make an LED glow bright or dim just by turning a knob? then this simple Arduino Based Control LED Light Circuit with Potentiometer does that same thing. Turn the knob to adjust the LED light from soft to full brightness, also it is a fun and easy way to learn how Arduino reads […]
