Summary of BRIDGE BIDIRECTIONAL DC MOTOR SPEED CONTROL PWM PIC12F629
This project describes a lightweight, fully solid-state bidirectional DC motor speed controller using a PIC12F629 microcontroller and PWM. Designed for model aircraft or small boats, it features SMD construction, 10A current capacity, automatic low-voltage cutoff (6–12V), and a 1A BEC. The circuit uses an H-bridge with 2N7002 MOSFETs and includes safety arming logic to prevent startup unless the throttle is neutral.

AIRCRAFT MOTOR SPEED CONTROL
Whilst there are many commercially reversible speed controllers available, most are designed for high performance model cars or boats, and therefore are large and expensive. I wanted a lighweight ESC for fitting into a small scale boat or submarine.
