SKU_BOS0024_Motor_Controller_Module

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.

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.
