LDR Detection: The LDR module will detect the changes in light intensity caused by the torch and convert them into electrical signals. Arduino Processing: The Arduino Uno will receive the electrical ...

Arduino main board (I used an Arduino UNO) Active buzzer module Sound sensor (conected to Analog 0) RGB light LDR (light) sensor HC-SR04 Ultrasonic sensor 0.96 inch OLED display (connected to A4 and ...

Here Arduino, LDR module, SMPS module and few other components too. The principle of operation the LDR detects light and transmits the information to Arduino. Through the relay mechanism, the Arduino ...

This technique is implemented with help of LDR's, microprocessor and IRF520 MOSFET Driver Module to measure as well as to control the intensity of light as per the requirement of the user.

In this Arduino IR sensor module tutorial we are explaining how to connect IR sensor module with Arduino Uno and write the code to get the IR motion sensor working.
