Me Dual Motor Driver modulet kan drive 2 DC motorer via RJ25 portene der sidder på med en strømforsyning på 6v-12v. Det kan også styre farten via PVM fart kontrolleringsfunktionen.

IC der bliever brugt i modulet er en effektiv lavt varme MOSFET med overforsynings beskyttelsesfunktion. Dets røde ID på portene betyder den skal i Rød port på Orion boardet. ca

Overview

The Me Dual Motor Driver module can drive two DC motors by the onboard RJ25 port with power supply of 6V-12V, and it also has the PWM speed regulation function. The IC used in the module is an efficient, low heat dissipated MOSFET with over-current protection function. Its red ID means that it should be connected to the port with red ID on Makeblock Orion.

Wiring mode

● Connecting with RJ25
Since the port of Me Dual Motor Driver has red ID, you need to connect the port with red ID on Makeblock Orion when using RJ25 port. Taking Makeblock Orion as example, you can connect it to ports No. 1 and 2 as follows:

Guide to programming

● Arduino programming
If you use Arduino to write a program, the library Makeblock-Library-master should be invoked to control the Me Dual Motor Driver.
This program serves to make two DC motors rotating simultaneously in the same or inverse direction through Arduino programming.微信截图_20160203153738

Principle analysis

Drive principle of DC motor: The DC motor is added with drive circuit in order to better control the rotational direction and speed of motor. As a common circuit designed to control the DC motor, the H-bridge drive circuit is mainly to implement forward and reverse drive of DC motor. Its shape is similar to the letter H, the location of four switches (MOSFET) are called the bridge arm, and the DC motor serving as load is like a bridge across the top, so it is called the H-bridge. To drive a lot of integrated motors, the core of drive chip is the H-bridge. The opening and closing states of 4 switches can be combined into 4 working states for the motor: forwarding, reversing, braking and coasting.
