Projects With Arduino Uno 2021 Jun 2026

2 Servo motors (continuous rotation) or 2 DC motors + L298N driver, 2 Light Dependent Resistors (LDRs). Concept: Place two LDRs on the left and right of the chassis. If the left sensor is dark and the right is bright, the robot turns left to chase the light. This is a "Photovore" (light eater). Learning Outcome: Differential steering logic and sensor fusion.
