Скачать или смотреть How to Control DC Motors With ANY RC Controller (Servo Hack)

In this tutorial, I'll show you the ultimate "Servo Hack" I use to convert a standard RC receiver signal into a fully variable PWM signal for perfect DC motor speed and direction control. I'll guide you through my complete, from-scratch build of a 3D-printed RC car using this clever and affordable method.

The Problem I'm Solving:
A standard RC receiver signal, designed for servos, consists of a 1-2 millisecond pulse within a larger 20-millisecond cycle. When I connect this signal directly to an H-bridge motor driver, my DC motor will only rotate in one direction and at a fraction of its full speed—roughly 10% of its power at maximum.

The Solution ( "Servo Hack"):
I found that the circuit board inside any standard servo motor is the perfect tool to solve this problem. I'm going to show you how I repurpose this circuit to act as a signal converter. It reads the 1-2 ms pulse from the receiver and outputs a proper PWM signal with a 0-100% duty cycle, which allows the H-bridge to drive my DC motor forward and reverse at full variable speed.

In this step-by-step guide, I'll show you:

How I took a CAD model and 3D printed my RC car's chassis. (My print for this project took two hours).

How I disassemble an old servo motor to access its internal controller board.

How I desolder the small motor from the servo board and attach signal wires that will connect to my H-bridge module.

The complete wiring for my project, connecting the FS-i6 receiver module, two of my servo-hack converters, the H-bridge, and the motors.

How I use the servo board's potentiometer to adjust the neutral point, ensuring the motors don't spin when my controller stick is centered.

This method is perfect for any DIY robotics or RC project and saves me from buying an expensive, specialized Electronic Speed Controller (ESC).
