Fire Alarm Circuit using IC LM358
This Fire Alarm Circuit using IC LM358 is simple but smart, as it uses a 10k thermistor and LM358 IC; also it watches heat using a thermistor and makes buzzer ring when danger comes. Additionally, this circuit is cheap and is good for home, school projects and safety demos. Circuit Working: Parts List: Components Value […]
Arduino LED Dimmer Circuit using IR Remote
This project for Arduino LED Dimmer Circuit using IR Remote make simple LED look like smart light. Here, LED listens to IR remote, IR receiver reads remote signal and then Arduino change LED brightness using PWM. With Arduino and few parts, we can change brightness sitting on sofa and it feel like small home-automation system; […]
IR Transmitter and Receiver Circuit using 555 and 4017 IC
This project is IR Transmitter and Receiver Circuit using 555 and 4017 IC, as it works with infrared light and it also has two parts transmitter and receiver. Transmitter sends IR signal and receiver catches signal and turns relay ON or OFF and furthermore, it can control small home device without wire. Circuit Working for […]
Automatic Street Light Circuit using Arduino
This project for Automatic Street Light Circuit using Arduino show street light can think smart. Light will turn ON when night come and light will turn OFF when sun come; therefore no need of a human to press a switch. Arduino and LDR do all work automatic and it also save power and make street […]
Smart Street Light Control Circuit
