About This Idea
Use Arduino or Raspberry Pi to create a basic robot. Learn electronics, programming, and mechanical design while building something that moves and responds to commands. Robotics combines programming, electronics, and mechanical engineering in a hands-on way. Building your first robot teaches problem-solving, debugging, and the satisfaction of seeing code come to life in the physical world. Start simple with a line-following or obstacle-avoiding robot, then expand to more complex projects.

Common Challenges & Solutions
Every beginner faces obstacles. Here's how to overcome them:
⚠️
Robot doesn't move or moves erratically
Solution: Check motor connections - wires might be loose or reversed. Verify motor driver is powered (separate power supply needed). Test motors individually. Check code - make sure motor pins are correct. Ensure battery has enough power.
⚠️
Sensors not reading correctly
Solution: Verify sensor wiring (VCC, GND, signal pins). Check sensor is getting power (LED should light if it has one). Test sensor with simple code first. Adjust sensor sensitivity in code. Make sure sensor is mounted correctly (not blocked, right distance).
⚠️
Code won't upload to Arduino
Solution: Check USB cable (data cable, not just charging). Select correct board and port in Arduino IDE. Install correct board drivers. Try different USB port. Press reset button on Arduino before uploading.
⚠️
Robot keeps falling apart
Solution: Use stronger materials for chassis (thick cardboard, plastic, or 3D printed). Secure components with screws instead of tape. Use zip ties for wire management. Add structural support. Consider 3D printing a proper chassis.
