- Two IR sensors detect black lines on a white surface.
- The microcontroller processes the data and controls the L293D motor driver to adjust motor speed.
- The robot follows the designated path efficiently.
2. Obstacle Avoidance Mode
- The ultrasonic sensor measures the distance to obstacles.
- If an obstacle is detected, the robot stops and changes direction.
- This feature is crucial for autonomous navigation.
3. R/C Car Mode
- The ESP-12E allows wireless control via a smartphone app.
- Users can manually navigate the robot like an R/C car.
- This feature adds a fun and interactive element to learning.
4. Edge Detection Mode
- Uses IR sensors to identify sudden drops (e.g., table edges).
- The robot stops or reverses direction when an edge is detected.
- Ensures safety in high-surface environments.
