You can use ATtiny45 or ATtiny85 chip for this project.

Here’s the pin layout of the ATtiny45 and ATtiny85:

For this tutorial, you’ll need:

• Arduino Uno or Duemilanove (w/ an ATmega328, not an older board with an ATmega168)
• ATtiny45 or ATtiny85 (8-pin DIP package)
• a 10 uF capacitor (e.g. from Sparkfun or from Digi-Key)
• a breadboard
• jumper wires

Download: Arduino software, attiny45_85.zip
Here’s how to turn the Arduino board into a programmer for this project.

• Run the Arduino development environment.
• Open the ArduinoISP sketch from the examples menu.
• Select the board and serial port that correspond to your Arduino board.
• Upload the ArduinoISP sketch.

Pin connections:

• ATtiny Pin 2 to Arduino Pin 13 (or SCK of another programmer)
• ATtiny Pin 1 to Arduino Pin 12 (or MISO of another programmer)
• ATtiny Pin 0 to Arduino Pin 11 (or MOSI of another programmer)
• ATtiny Reset Pin to Arduino Pin 10 (or RESET of another programmer)

It should look like this once its done.
