The project is meant to control the speed of Brushless DC motor using Arduino and Bluetooth communication.

EXPANDED TECHNICAL DETAILS

High-Power Brushless DC (BLDC) Control

This project bridges the gap between a smartphone app and the high-speed world of brushless drone or RC car motors.

  • ESC Interfacing: The Arduino communicates with an Electronic Speed Controller (ESC) using standard Servo PWM (1000us - 2000us pulses). The ESC then handles the complex 3-phase commutation required for the BLDC motor.
  • HC-05 Wireless Link: The user adjusts a slider on an Android app, which sends a speed value (0-100) to the Arduino via Bluetooth.

Safety Logic

  • Armed State: To prevent accidental start-up, the firmware requires a "Zero-Throttle Arming" sequence before the motor will spin, mimicking professional aircraft safety standards.
