It is used in motor speed detection, position detection and security systems. Circuit Working: Parts List: Component Value Quantity Resistors 1k 1/4 […]
PIR Motion Detector Circuit using Arduino
Turn Arduino into a motion spy! With just a PIR sensor, buzzer and LED we can detect movement easily. Whenever someone passes it spots movement and warns us with light and sound. This PIR Motion Detector Circuit using Arduino is for beginners and makers. It is fast to build, fun to use and full of […]
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 […]
Arduino Based Coin Value Identifier Circuit
This Arduino Based Coin Value Identifier Circuit is a simple coin sorting machine. It can detect and sort 2 Rs, 5 Rs, and 10 Rs coins. Each coin type is sensed by different IR sensors. The Arduino reads which sensor is triggered and shows value on LCD. This project is useful for small vending machines […]
