motor controller

PIC18F452 and DC motor controller.

Hey folks.

 Becausse the PICAXE kit already ships with all the components (er, most of it) glued, I wanted something more challenging. So, I am trying to build my robotic brains from scratch. 

Whilst I have come across quite a few (video) tutorials with circuit diagrams using PIC microcontrollers, I am not able to use a motor controller. One such is here: http://www.seattlerobotics.org/encoder/200001/simplemotor.htm. 

Can I get a little help ?

I need a little help with my Pololu Micro Dual Serial Motor Controller.... I am trying to use it with my arduino robot but I have no clue where to start code wise  ... where can I get sample code ... or even a guide on how to code for it .. I am sort of stuck on  this .... any help is appreciated greatly :)



Motor control




I'm building a robot based on my old RC-car and an arduino. The motor-control in my cars is "mechanical" where a servo switches the motor on/off etc. I would like an electronic motor-control instead...and i'm pretty lost.

Do you know a simple motor-control that will make the motor go forward,  just for a start? ;)

I think my motor draws a lot current so L293D is out of question..


Description An H-bridge circuit typically provides motor control in robotic designs. Low voltage, low amperage control signals (TTL) are used to control motors. … Read more

Arduino: How to make your first robot with..

When writing this, LMR only offers "Start here" - instructions on how to make your first robot, using Picaxe.

"Nebster" wrote to me, and asked if I could do a parallel, using Arduino, and I think that is actually a very good idea (now that Picaxe refuses to pay me commission, haha)

Focus should be on making first timers get a robot up and running at a low cost, and most importantly learn how to hook up motors, a servo, and a analogue input in "no time".

This is a motor driver that I like because of this: It is usable from 6 to 50V, at up to 4A total output currentIt has a 5V output, so you can just hook up any … Read more

Relays are an alternative to motor-controllers. They do consume a little power from your battery when in either on or off position (turned on) - but they also do … Read more

how to program for pololu on arduino...

now that I got my pololu controller how do i use it with arduino? (as in coding)
