DIY Dual Stepper Motor Driver Shield for Arduino

Stepper motors are brushless DC motors which can move in discrete steps thanks to the special coil arrangement inside. They are very popular in DIY and industry projects which require accurate mechanical movement control.  In this SoloPCB project, we are building a dual stepper motor driver shield based on two Allegro A4988 ICs which can supply up to 35V and 2A and provide overcurrent and thermal protection ...

Easy, Reversible Motor Control for Arduino (or any Microcontroller) using arduino

This project uses just three main components to provide forward and reverse control for a single motor.  You can easily interface it to an Arduino or any other microcontroller. It's so simple - you can wire it up "free-form" without a circuit board in about 15 minutes. Features: All parts available at Radio Shack for under $9 Supports PWM for variable speed control Handles up to 5 amps peak / 2.5 amps conti ...

World’s Smallest Stepper Motor with Arduino and EasyDriver

This little wonder of electromechanical engineering came from inside a laser diode sled of an HP CT10L Bluray drive I’ve opened some time ago. The device on the picture consists of several parts, all easily fitting on a dime coin: a bipolar stepper motor with lead screw, a linear stage, a lens, and even an end position sensor (I’ve yet to make use of the sensor though). The entire assembly is only 14mm x 9m ...

Stepper Motor drive from Arduino

Stepper Motor drive from Arduino In this tutorial we will show you how to connect a bipolar stepper motor to an Arduino Uno board. The stepper motor we are using is the Sparkfun Stepper Motor but you can use any other 4-wire bipolar stepper motor. Because a stepper motor draws a higher current than the Arduino processor can handle we are going to use a Quad half H-Bridge chip to control the stepper motor. T ...

Adafruit Arduino Motor Shield Build

Overview The Arduino Motor Shield is based on the L298 (datasheet), which is a dual full-bridge driver designed to drive inductive loads such as relays, solenoids, DC and stepping motors. It lets you drive two DC motors with your Arduino board, controlling the speed and direction of each one independently. You can also measure the motor current absorption of each motor, among other features. The shield is T ...

New energy efficiency rules will change motor control design

Motor control is becoming the power industry’s fastest changing technology area. The reason for this is the requirement to improve energy efficiency from the millions of motors which are used in our homes, factories and cars. New developments in motor controller design, current sensing and control algorithms will be needed if new and more stringent efficiency targets are to be achieved. The main design elem ...

Use xbees (series 2) to control a motor

Using two xbees, an arduino, an xbee explorer, and an h-bridge, wirelessly control a DC motor to spin in both directions (last video). Note: I used the xbee I linked to, but for a one to one communication, rather than a network of wireless devices, xbee series 1 would do fine, but the AT commands are slightly different. Step 1: Materials Arduino 2 xbees Any DC motor power supply or battery usb mini cable xb ...

Control your motors with L293D and Arduino

After long research and trial and error, I have came up to a new walkthrough regarding this nice chip, the L293D. Each project is one project and each one has its own unique power configurations, so you must be aware of the best battery choice and how to distribute voltage through your robot. I strongly advice you to read the following articles: Picking Batteries for your Robot Once you've decided on batter ...

Tutorials for Arduino Getting Acquainted with Arduino

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. The microcontr ...

Using Servo Motors with Arduino

In this instructable, I am going to show you what a servo motor is, how to use it, and ideas for starting projects using it. I used arduino to control my servo, I added how to use a 555 in some of the later steps. Step 1: What is a Servo motor If you are like me, then you knew very little about servo motors, and how to use them, so we should start from the beginning. A Servo motor uses pulse width modulatio ...

Simple 2-way motor control for the arduino

When I say simple, I don't mean use a speed control. But control the motor directly without any external circuitry. Here's how: How this came about: I recently was working on an instructable about charlieplexing with an arduino. And I was wondering if the same principle would work with motors to some extent. So I came up with the idea that if you used a motor instead of an led you could have 2-way cont ...
