This page will show you how to put together a simple stepper motor driver board that can be controlled with an Arduino. I built mine to use with my heliostat projects, but it could be used for other things too. Update: I no longer use this driver board with my sun tracking / heliostat system.

Finally, I finished reading the datasheet. It didn’t give much information about how to connect the motor controller to a micro-controller. I used the simple circuit I found from a post in Pololu’s forum: Using Dual VNH3SP30 Motor Driver with arduino @ http://forum.pololu.com/viewtopic.php?f=15&t=1923. Dual VNH2SP30 Motor Driver Carrier MD03A to Arduino Circuit Diagram I connected

This is the second part of our BaW-Bot (Bells-and-Whistles Bot) build – 5 separate instructables that look into different Arduino-related technologies, combining to create a Bot with all the bells-and-whistles. Part 1: Build an Arduino on a Board Part 2: Build the motor-controller & body Part 3: Adding Sight and Touch Part 4: Blinging up

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
Use xbees (series 2) to control a motor Continue Reading
A simple diagram demonstrating how to regulate the velocity of a DC motor using a potentiometer connected to your Arduino device. Additionally demonstrates the method of utilizing a TIP120 transistor for enabling the Arduino to manage a more powerful power source. Transistors consist of 3 pins, with the third pin (Base) enabling control of the

This is a quick guide with a bit of extra info (pin configurations etc..) that I’ve learnt along the way on how to use the L293D with the Arduino, showing that we can: A) Use a supplemental power source to power the DC motor B) Use the L293D chip to drive the motor C) Use

Very simple basics of building a circuit to control a servo using Arduino and PWM For this you will need: Arduino Board – I’m using a Duemilanova ATMEGA328 Arduino Sketch software – I’m using version 0015 Arduino Servo Library found here save it to lib/targets/libraries if you don’t already have it A Servo that requires

Buildings account for 20-40% of total energy use in developed countries. Window shades (or blinds) can help to reduce building energy use and improve visual comfort (i.e., reducing glare and increasing daylighting). A recent study showed that occupants are fairly inactive when operating manual roller shades (O’Brien et al. 2013) which could lead to increased

With our new project, JustAddSharks, we are very keen to support the development of open source control software for laser cutters. We are more than happy for people to modify our laser cutters, replace the control system with something suitably open source and then let us know how it goes. Realistically though we’re going to

Connect the Arduino outputs with 5 volt power to the relay coils. Use a separate 9 or 12 volt battery for powering the motor. Connect the 9 or 12 volt power to the relay contacts and the motor. Be sure to avoid connecting the 9 or 12 volt power to any of the Arduino input
