PROJECT – CONTROLLING A MOTOR – FORWARD AND REVERSE SWITCHING

INTRODUCTION This project will show you how to control the rotational direction of a small motor without using any mechanical relays. The Texas Instruments L293D dual H-bridge IC has two separate control circuits and can control two conventional DC motors or one stepper motor. In this project we use one half of the IC to …

Driving a Unipolar Stepper Motor with a ppDAQC Pi Plate

Stepper motors are versatile devices that allow precise and repeatable angular control. They are used in disk drives, translation tables, and 3D printers to name just a few applications. They typically come with two different wiring arrangements. The most common arrangement is four wires that are connected to two coils. This is called a bipolar …

Controlling a stepper motor with the Raspberry Pi and Piface

Updated April 2015 I have made this because I have found no projects using the PiFace. Forum topic at www.raspberrypi.org: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=37&t=54314&p=413902 Here is a simple project that only needs a Raspberry Pi, PiFace, Python, jumper wires, and a stepper motor – that’s it! Step 1: Schematic Step 2: Connect the PiFace to the Raspberry Pi …
