In this instructable I will show you how you can make your own Atting programming shield for the arduino and then use the arduino as a programmer.
Usually If you don't have a shield you can do a breadboard version to program the ATtiny. (Step1)
But here I'll show you how to program it and with a couple of components make a nice shield for the arduino, which makes programming much easier!

For more information on how to program the ATtiny click on: MIT High-Low Tech web page.

Hopefully you will be familiarized with the arduino environment, if not more info at Arduino.cc
And still, it's quite easy to set everything up.

Well, all the things you will need to make the shield are:

X1 3mm Red LED
X1 3mm Green LED
X1 10uf 50V electrolytic capacitor
X1 8-pin 0.3" socket
X1 SPST tactile switch
X1 220 ohm resistor
X2 Male pin headers
X2 4-pin female sockets
X1 ATtiny 45 or 85

Things you might all ready have and will be needed:

Soldering Iron
Solder
Tweezers

And of course your Arduino, I made it on the Arduino UNO R2.

Looks like ATtiny has analog in and PWM out.

I've only done digital, but I'll be sure to try analog! :)
