Project Idea
Development and testing of an e-bike speed controller using an STM32 microcontroller, focusing on throttle input processing, motor speed control, speed display, and start/stop operations.
Project Description
The project involves designing an e-bike controller system that uses an STM32 microcontroller to read throttle inputs via a non-contact throttle position sensor working on Hall effect or magnetoresistive technology. The STM32 processes the throttle signal to control power to the e-bike motor through a motor driver, varying motor voltage to control speed and power. A Hall effect speed sensor provides wheel RPM feedback, which the controller displays on an OLED screen. The system also manages bike start and shutdown through a main switch, enabling efficient speed regulation, user-friendly monitoring, and power management.
