TL;DR

A C++ library for precise motor speed control and power balancing across multiple motors, using encoder feedback so you can focus on your project instead of low-level motor details.

Why would anyone build with this?

REASON 1

Build a multi-wheel robot where each wheel spins at the same speed to prevent drifting.

REASON 2

Create a conveyor belt system with coordinated motor speeds for smooth item transport.

REASON 3

Drive an automated turntable or rotating mechanism that needs consistent rotation speed.

REASON 4

Balance power across multiple motors in any project where one motor overworking would cause failure.

Requires compatible motor hardware, encoders, and a supported motor driver platform, the README does not specify setup steps or hardware compatibility so you must inspect the code.

Wtf does this do

The scrapcontroller library helps make motors spin at the exact speed you want and share power evenly when multiple motors are involved. Instead of fighting with low-level details every time you wire up a motor, this library handles the interaction between the motor and its encoder (a sensor that tracks how fast the motor is spinning) so you can focus on the bigger picture of your project. At a high level, it reads data from the encoder to figure out the motor's current speed, then adjusts the power going to the motor to hit your target speed. When you have several motors working together, it also balances the power load between them, which helps prevent one motor from overworking or burning out while another lags behind. This kind of feedback loop, read the speed, adjust the power, repeat, is the core of what the library does behind the scenes. This would be useful for anyone building physical projects with motors where consistent speed matters. For example, if you are building a robot with multiple wheels, you need each wheel to spin at the same rate or the robot will drift or pull to one side. The same applies to conveyor belts, automated turntables, or any mechanism where smooth, coordinated motion is important. Hobbyists, students, and engineers working on these kinds of electro-mechanical systems would get the most out of it. The project is written in C++, which is standard for embedded systems and hardware control. Beyond that, the README doesn't go into detail about specific hardware compatibility, setup steps, or advanced features, so you would need to dig into the code itself to see exactly which platforms or motor drivers it supports.

Yoink these prompts

Prompt 1
I have a robot with four wheels, each driven by a motor with an encoder. Using scrapcontroller, how do I set up all four motors to spin at the same target speed and share the power load evenly?
Prompt 2
I want to use scrapcontroller for a conveyor belt project. How do I connect my motor and encoder to the library and set a target speed so the motor maintains consistent rotation?
Prompt 3
How does scrapcontroller's feedback loop work for balancing power between multiple motors, and how do I configure it so no single motor burns out or lags behind the others?
Prompt 4
I am building an automated turntable with a single motor and encoder. What is the minimal setup code in scrapcontroller to read the encoder speed and adjust motor power to hit my target RPM?
