Pololu Motor Controller Testing and Troubleshooting

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 DiagramI connected everything according to ...

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 ...

4 Servo drive CellBot which can be remotely controlled using Arduino

I started with an idea of what I wanted to do from the beginning but one attempt after another I finally got to where I am now. This robot can be remotely controlled from anywhere in the world and driven around the house. I can see through it's eyes. Here is a brief run down. I'll get into more later. *I have taken a 3.5 floppy disk case as a body and added 4 servo's converted to continuous operation for th ...

Using the Sparkfun Motor Driver 1A Dual TB6612FNG using Arduino

As a beginner myself, I struggled to find a one-stop set of instructions to get up and running with Sparkfun's Motor Driver 1A Dual TB6612FNG.  This motor driver breakout board is exceptional value, is beautifully small, but does need a little more effort to get it working. The TB6612FNG is an H-Bridge driver - I won't go into the technicalities of how it works, but the end result is that it can turn a conn ...

Arduino – Control a DC motor with TIP120, potentiometer and multiple power supplies

A quick circuit showing how to control the speed of a DC motor with a potentiometer with your Arduino board. Also shows how to use a TIP120 transistor to allow the Arduino control a larger power supply. Transistors are 3 pin devices, which via the 3rd pin (Base) allow it to control the current passing through the other 2 pins (Collector and Emitter). So for this tutorial I am using the power from the Arduin ...

Control a DC motor with Arduino and L293D chip

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 a switch to change the direction of the motor UPDATE: If you intend to use this for robotics then please check out this page here to get ...

Controlling a Servo with Arduino

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 no more than a 5V supply I’m using a Futuba S3113 A Potentiometer (A dimmer switch) Brea ...

DIY Arduino Motor Shield [for only $8!] (L298N 2x4A)

Today, I'm going to show you how to make an Arduino motor shield (driver) at a low cost. It works splendidly, its posses almost all the characteristics of the original Arduino motor shield. It's almost considered as a clone. The original Arduino motor shield has the same motor driver chip (L298), the only difference with it, is the package type, my project contains the vertical version of the chip L298 (wit ...

Earth Globe Rotating With Arduino Or Raspberry Pi Controlled Stepper Motor using arduino

This instructable describes how to upgrade your globe to a motorized version. It looks amazingly better on the shelf when it is slowly rotating, and any demonstration with your kids (to explain the day/night cycle or the seasons) will gain in interest. No need to rotate the globe by hand while painfully holding the flash light with your teeth. The instructions correspond to the various parts I had at my dis ...
