In recent years, electric bicycles (e-bikes) have gained significant popularity as an eco-friendly, efficient, and cost-effective mode of transportation. Central to the functioning of an e-bike is the speed controller system, which manages motor performance based on rider input and system conditions. This project focuses on the development of an advanced E-Bike Speed Controller System using the Arduino microcontroller, recognized for its simplicity, open-source ecosystem, and suitability for real-time embedded control applications.

The system is designed to intelligently monitor and regulate the speed of the e-bike for smooth and responsive operation. A throttle is used by the rider to set the desired speed, while a speed sensor continuously monitors the actual velocity of the bike. The Arduino processes this data and generates control signals that are sent to the motor driver, which in turn controls the e-bike motor. An OLED display is used to present real-time information such as current speed, battery level, and overall system status to the rider. Additionally, the system incorporates a buzzer and LED indicators to provide alerts in the event of system faults or unusual operating conditions.

The hardware is implemented on a custom-designed PCB that integrates all the essential electronic components, such as resistors, capacitors, and transistors, along with secure cable and connector interfaces. These components are housed within a robust buoy body frame, ensuring the system's durability, safety, and reliability under various environmental conditions.

This project not only demonstrates embedded system integration using Arduino, but also contributes to the advancement of intelligent, energy-efficient, and user-friendly e-bike systems, aligning with the goals of sustainable and smart mobility solutions.
