ATtiny programming with Arduino

After this Instructable you should be able to program an A Ttiny85/45 with an arduino. It may sound complex but it really isn’t. After doing some research I could not find to much info on how this could be done. I however did find http://www.instructables.com/id/Program-an-ATtiny-with-Arduino/. This Instructable is my interpretation of what I learned from Randy.

Step 1: Things you will need

Arduino
AT tiny 85/45 – available from Mouser  556-ATTINY85-20PU  Need more info on the AT tiny check out the data sheet here.
Bread board ( or the 8 pin shield from Instructables )
Bread board jumper wires
Led- 5
330 ohm resistor-5
1uf 50V electrolytic capacitor

Step 2: Set up

You will be using the following arduino pins (see pic)
5V +
5V Ground x2
10
11
12
13
Reset

Wire up the bread board with the jumper wires as follows or see pic:
Note: be sure to not the dimple direction.

ATtiny  pin# 1 to arduino pin# 10
ATtiny  pin# 4 to arduino 5v ground
ATtiny  pin# 5 to arduino pin# 11
ATtiny  pin# 6 to arduino pin# 12
ATtiny  pin# 7 to arduino pin# 13
ATtiny  pin# 8 to Arduino 5v +

Now lets move onto adding our leds. Add the leds to the bread board as see in the pic keeping in mind the polarity of the leds.
Add the resistors to the positive side ( side without the flat part ) each led with get a resistor. Take some jumper wires from the resistors and connect them to the following ATtiny pins.

ATtiny pin# 5 this will be programmed as pin 0 in the sketch
ATtiny pin# 6 this will be programmed as pin 1 in the sketch
ATtiny pin# 7 this will be programmed as pin 2 in the sketch
ATtiny pin# 2 this will be programmed as pin 3 in the sketch
ATtiny pin# 3 this will be programmed as pin 4 in the sketch

Step 3: Setting up the arduino to program

Setting up the arduino to program is not a permanent thing. All this will do is load a sketch that will allow you to program the chip then when you want to use the arduino you simply change the sketch.
Fist things first you will need the program, down load it by clicking attiny45_85.zip  be sure that you are using arduino program version 0022.
