So i was going to buy some chips. However I am not entirely sure how to wire them up.
Do i just follow this. Wire up 9 volts to the Vcc port and soder everything else to its own pin? Or am I overlooking some important compnets?
Also i read the article on ardunio.cc but without the picture i am quite confused. Thanks!

First the chip can never have more then +5vdc wired to it's Vcc pin. Also Avcc pin needs +5vdc, reset pin needs a pull-up resistor to +5vdc. Crystal with two caps needed for the two clock pins, two ground pins wire to ground. There should be two .1 ufd caps wired to Avcc and Vcc pins to ground.
You really should follow someones existing design and layout as you sound rather inexperianced?

I couldnt find anything if you could link me that would be great! I just bought an ardunio so im going to mess around with that first.
Minimal Arduino with ATmega8 – todbot blog take a look at this - this is for atmega8 but atmega8 has the same pinout as 168/328 also if you use a 9v battery you may want to look at a voltage regulator
Couldn't fnd anything? I continually post this bare minimum diagram.
In addition, you can get a board here that pretty much does this, and get the parts to populate it really inexpensively at www.dipmicro.com

You can reduce component count by replacing the crystal and its load capacitors with a 3 pin ceramic resonator... Have at least one 10uF decoupler as well as the 0.1uF ceramics... I would add provision for a voltage regulator too.
