// 1) Read OEM push buttons to set the mode (33 RPM, 45 RPM, 78 RPM, Reverse, Start/Stop. // 2) Set the PWM to the H-bridge driver (L298N) via arduino PWM output based on the hall sensor RPM speed ...

Notes: Arduino program for measuring the rpm of an unidentified DC motor using a hall effect sensor to measure rotation of a disc with an embedded magnet For this project a custom mount was created in ...

Would you believe it, the ESP32 popular Wi-Fi and Bluetooth chip has a built-in Hall effect sensor. Espressif Systems makes the chip, and its ESP32 data sheet has nearly no mention of the Hall sensor ...
