Gravity: 130 DC Motor

Introduction

Gravity 130 DC motor is a very interesting module, the module does not need additional motor driver board, you can use Arduino board to drive it easily. And the speed control could be realized with PWM　signal. Very popular with DIY project

Specification

Operating Voltage: 5v
Interface type: Gravity 3-pin digital sensor interface
Dimension: 52 * 27 mm
Weight: 40 g

Tutorial

We will use Arduino to control module speed.
