Arduino UNO-Powered Light Tracking Robot

In this project, we’ll create a basic light-following robot using Arduino UNO. It’s a great beginner project that employs LDR (Light Dependent Resistor) sensors for light detection and an MX1508 motor driver for control.

Working Principle

Motor Control:We use a two-wheeled chassis car with straightforward motor control:

• Idle: Both motors stop.
• Turn Left: Left motor stops, right motor rotates forward.
• Turn Right: Left motor rotates forward, right motor stops.
• Move Forward: Both motors rotate forward.

Sensor Control:We use two LDR sensors:

• Right Sensor Detects Light: Turn right.
• Left Sensor Detects Light: Turn left.
• Both Sensors Detect Light: Move straight.
• No Light Detected: Stop.

Circuit Diagram:

Circuit connections are more simple. Direct to the schematics in the respective section for clear understanding.

• LDR modules connect to digital pins 8 and 9.
• MX1508 motor driver connects to pins 10 and 11 for motor control.
• Power inputs connect to the Arduino’s 5V and GND.

Conclusion

In this project, we’ve successfully built a simple light-following robot using Arduino UNO, LDR sensors, and an MX1508 motor driver. This robot provides a hands-on introduction to sensor-based control and motor management, making it an ideal project for beginners.
