Title: $50 robot where to start?
Post by: Revlex on January 08, 2010, 03:22:26 AM

I have a question, iv'e looked on the forum and Google but couldnt find it!

Here's my question:

How do i know what electronics i need and built a correct circuit for the robot. for instance take the €50 robot tutorial wich dates from somewhere in 2008..........
the tutorial  says i need this, that and a thingybob more of flash memory and stuff, since it's outdated now. How do i know what i need to buy?:O

So if some one could tell me that i would be so happy!!!!

greeets,

A Dutch Man

Well, the only real thing that can be outdated is the microcontroller.
The upgrades for this are the atmega168 and the atmega328.
The 328 has the most flash memory etc...

does the new types of microcontroller need a other circuit bord since it's not the same?

The pinout connector is the same. Nothing externally is different, its an exact switchout for the mega8.
The only difference is the defines in the code. Instead of defining the mega8 you do the mega168/328.

The 8/168/328 are all the same as this.

make sure you get the 28 pin mcu as the 168 can come in a 32 pin format. I am not sure about the 328 though.

Ok it could be just me but since jokers post........ im confused about the pins and the shortnames like MCU

"MCU" just means microcontroller. He means to be sure you are getting the chip in dip form.
When you buy, make sure it says dip somewhere.

since it's hard in europe to find some stuff is this a atmega328 28 -pin dip? since i'm getting confused with the name ATMEGA328p-PU.
