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 ...

Dark sensor Light and dark detection using an LDR For this project, let’s stick to the LDR sensor module so we can select the light or dark detection by placing jumpers. We’ll be using this module to ...

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 ...

Working of Arduino Color Mixing Lamp: As we are using three LDR’s so, when light incident on these sensors ,it’s resistance changes as a result voltages also changes at analog pins of Arduino which is ...

In this article, we are going to make a Sun Tracking Solar Panel using Arduino, in which we will use two LDRs (Light-dependent resistor) to sense the light and a servo motor to automatically rotate ...

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 ...
