What it does
Follows a black line on a white surface and detects neodymium magnets underneath the course.
How I built it
Soldered various components including resistors, IR emitters, photodiodes, power connections, a resonator. The motor was attached to the board via stand offs as a part of the project's specifications.
Challenges I ran into
The board had one power supply for both the sensors and the motor. The motor caused some noise in the hall effect (magnet) sensor, causing it to false trigger. Also, sometimes we would experience brown outs causing the robot to stop.
Accomplishments that I'm proud of
Being able to correctly design filter circuits by calculating resistor and capacitor values.
