This project is for small Electronic Eye Circuit using IC 4049. It can sense darkness or shadow. When light falls on LDR the circuit stays OFF. When light is blocked then LED and buzzer turns ON. It is like a magic eye circuit used for security or door alarms. Circuit Working: Parts List: Component Value […]

RGB LED Color Control Circuit with LDR and Arduino
Do anyone like lamps that change color with magic? This project for RGB LED Color Control Circuit with LDR and Arduino makes its real. Using RGB LED and three LDR light sensors, we can create a smart lamp that mix colors based on light around it. Just a simple circuit and with some code, we […]
LDR Light Sensor Circuit with Arduino
This project is for smart LDR Light Sensor Circuit with Arduino. It can feel light like human eye. When dark come, it turn ON lamp by itself. When light come, it turn OFF lamp automatic. No need to press any switch. It save time and save power. It is small, simple and very low cost […]
LDR Based Aircraft Warning Signal Light Circuit
In tall buildings, towers or high structures it is important to show warning light for aircraft safety. Normally a red 230V LED bulb is used as warning lamp. This LDR Based Aircraft Warning Signal Light Circuit automatically switches ON the bulb in night and switch OFF in day. It uses LDR sensor, relay and small […]
Automatic Light Control Switch Circuit using IC 555
This article is for Automatic Light Control Switch Circuit using IC 555 It works with light dependent resistor (LDR). When light fall on LDR its resistance changes. That resistance change is converted by IC 555 and used to drive a relay. With relay we can connect lamp, fan, motor or other load. It is useful […]
