Light Following Robot using Arduino and LDR Sensor
Light Following Robot using Arduino and LDR Sensor
The Light Following Robot is a fun and educational robotics project that uses Arduino Uno and LDR (Light Dependent Resistor) sensors to detect and follow a light source. It mimics the behavior of light-seeking organisms and is great for learning sensor-based automation and basic robotics.
The robot is built on a chassis with two DC motors controlled by an L298N motor driver. Two LDRs are placed at the front to sense light intensity. When one LDR detects more light than the other, the Arduino signals the motors to turn toward the brighter side. If both LDRs detect equal light, the robot moves forward.

RFID-Based Attendance System using Arduino
RFID-Based Attendance System using Arduino
The RFID-Based Attendance System is a smart and contactless method to record attendance using RFID technology. It uses an Arduino Uno, RC522 RFID reader, and RFID tags/cards assigned to individuals.
