arduino-nano-ldr-photo-resistor-module The Arduino Nano LDR (Light Dependent Resistor) or photoresistor module detects changes in light intensity, providing analog output based on ambient light levels ...

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 ...

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 ...
