Title: Need help finding parts
Post by: GalacticNerd on July 07, 2009, 08:03:41 AM

Hello,

I'm trying to find a cheap and basic augmented microcontroller board.
Specs should match the 50$ one as close as possible.
Making it myself is a bit too hard, and I'd ike to start right away instead of spending hours of debugging my own board.

I prefer AVR's, or anything wich I can code in C with.

Also, what are the cheapest servo motors around?

Augmented in what way?

Have you looked at the Arduino? The Bare Bones Board?

I mean like having everything needed for some basic I/O.
I've looked at the arduino, and I'm considering it, but if there is a cheaper alternative for it... As long as it does the job.
It should be able to build the 50$ bot on, nothing fancy.

I prefer an assembled version of it, but it looks good.
I might buy an arduino after all, but since I'm in europe I need to find a place where I can buy from without a lot of shipping costs.

That should do well for you. One difference between it and the $50 robot board it that on the $50 robot board the headers are set up conveniently for servos and sensors - a group of three pins provides power/ground/signal. The Arduino just has a row of signals without the extra power/ground connections. It isn't that you can't get around this, but it isn't as convenient as the $50 robot board.

The Arduino board and development environment is a nice combination.

This comes preloaded with a bootloader.. so I don't need a programmer, I can just use USB, no?

that is correct all you will need is USB, if you want something like that for robotics I would check out the roboduino...

I think you posted to an Arduino. Or something very close to it.

You would only need a USB cable with an Arduino Duemilanove.

no this one although it is a bit more expensive than the original arduino
