I have been trying to get the Linistepper to work, however I can't seem the understand the working of the circuit. The circuit is here. The issues that I'm unclear about are: …

Hi all, I am trying to make a device that uses several motors all with an arrow fixed on top that has 8 fixed positions (N,NE,E,SE,S,SW,W,NW). I am trying to avoid servos and step …

How could I achieve this? What are the stepper motor facts and principless that I have to keep in mind to design a circuit to achive this goal? Are there any readymade/open so …

How do I incorporate a hobby-style motor into a project, physically. How do I mount it and connect a wheel to it? (Assume that I have a working H-bridge or even switches, and am …

Here's the circuit I'm working on, it's a robotic stringed musical instrument thing, that uses 6 DC motors and an Arduino Duemilanove - The resistors are 0.25w 1KΩ The transis …

This may be a lame question but, Speed controllers on big RC cars can they be controlled from Arduino? If yes, do they have a standart? do I control them using PWM values? What sho …

I have some nice gear motors that run on 12 to 24 volts, and want to use them in a medium-sized mobile robot -- maybe 30 cm * 30 cm for the base. I only expect it to run indoors, …

I put together the a Herbie the Mousebot the other day and he is FAST! Too fast to demonstrate in a small area. Have a look a this video to see just how he zips around. Document …

I am using Arduino and Ardumoto dc motor controller to drive a DC motor. I am kind of at lost because i have gone through 10 different motors. They either don't work( not enough po …

A customer has asked: I want to slow down a small hobby sized DC motor to a user variable range that runs from slow to zero RPMs. I would simply use a wall wart for a p …

Hi, I want to run/control a BLDC motor from a DVD/CD-rom player and found a schematic how to do this, the so called three phase inverter (see right schematic on this page: http:// …

I've been writing Linux character device drivers for other people's stuff for some time. I'd like to find a new hobby and the thought of making my own USB gizmos seems really neat. …

I'm looking to start a few different projects and stock up on some basic components - I was just wondering if anyone knows a good supplier of DC motors, stepper motors and servos? …

I am trying to build a robot and i have been having trouble getting a working h-bridge for my motors and i was wondering if anyone could help me work this out. i have 2 motors to …

My friend Jules asks: The aim is to get as many servo motor controls as possible - looks like the maximum an arduino will output is 14 ? http://arduino.cc/en/Main/ArduinoBoardMeg …
