Hall sensor feel magnet near it and it make signal when magnet is close, then signal can be digital or analog and here Arduino reads this signal. We can view the results on a computer or LED and the circuit checks motor speed, wheel speed or position. Arduino Code: Coding Explanation: Circuit Working: Parts List: […]
