Introduction
The motor controller module can be used to control robotic car to move, and drive the conveyor belt and the sliding device. To realize complicated functions, sometimes the single-direction rotation of a motor is not enough, and a motor controller module is necessary for achieving variable motor direction and speed, such as making electric fans and water pumps.
This module works well with maincontrollers such as micro:bit and Arduino, and can be used for not only Mind+ and MakeCode graphical programming but also non-programming projects.

Pinout
| Label | Name | Description |
|---|---|---|
| 1 | Signal | Digital Signal Line |
| 2 | VCC | Power Positive |
| 3 | GND | Power Negative |
| 4 | Motor + | Motor Power Positive |
| 5 | Motor - | Motor Power Negative |
| 6 | Toggle Switch | Motor Mode Selection |
Usage Description
The motor controller module provides 4 preset modes. Input the corresponding value to change speed and direction:
Motor Rotation Direction
Principle
When the motor drives an object to move, it converts electric energy into kinetic energy. This process will consume a large amount of energy, but the normal input module cannot provide enough for the motor, so we have to use a motor controller module to supply driving current for the motor. Besides, there are four modes for this motor controller module.
