Building an Arduino on a Breadboard

Other Hardware General Electronics

Hi,

I am considering running an arduino platform from a breadboard. Therefore I have been researching and I found out the below mentioned links

However, there is no tutorial for the ATMEL128 used in the UNO boards. Please help in getting a source, tutorial for the 128 as I need to reduce the components such as regulators and USB to serial to check for power.

BR,
Muhammad

The Uno doesn't use a 128, whatever that is.

The UNO uses an ATmega328 which is the same pinout as the ATMega168.

Apologies for the mistake :slight_smile:

Thanks for the pinout help. So you mean that I can use the mentioned link for making a breadboard implementation for UNO ?

That link uses the FT232 breakout board as the USB interface. It what the older type Arduinos used (Duemilanove and earlier). It makes little odds. Luddites like myself prefer the old boards over the Uno anyway. In common with the breadboard version they used a crystal rather than an oscillator for the 328. Once you have it running and the sketch sorted you probably won't need the USB anyway.

I have an Arduino on a breadboard. For programming I have a Max232 and a nine pin serial connector. I hook up a USB to 9 pin serial adapter and program it just like teh Arduino board. I bought a 328P with the bootloader already programmed. There is a YouTube video - Arduino Breadboard Tutorial -Arduino Workshop Project Video #1 - YouTube - put out by Sparkfun that shows how to hook it up.
