Step 1. Add Attiny85 Support - adafruit learning system Trinket Introduction Manual

Trinket support is not native to the Arduino IDE but, luckily, adding it takes only a few minutes
and you only have to do it once! This tutorial will base the IDE off of v1.0.5 which is current at
time of writing. You can try later versions but v1.0.5 is at least guaranteed to work
Adding Trinket support does not affect any other boards that are affected so you can
continue to use the IDE with any Arduino board currently supported.
Arduino v1.5+ has a different way of handling add-ons like this, please stick to v1.0.x
until we can determine what's different about v1.5! Thanks!

Step 1. Add ATtiny85 Support

Download the following file by pressing the button.
Unzip it and move the hardware folder from the zip file and place it into to your Arduino
sketchbook folder. Your sketchbook folder is the folder where the Arduino IDE stores your
sketches. This folder is automatically created by the IDE when you install it. If this is your first
time using the Arduino IDE, it will be empty!
On Linux machines, the folder is named "Sketchbook" and it is typically located in
/home/[username]
On Windo ws and Macinto sh machines, the default name of the folder is "Arduino"
and is located in your Documents folder.
This is a common source of confusion on Windows and Mac machines, your
sketchbook folder is not named "sketchbook" it is named "Arduino"!
Now you can start (or restart the the IDE) and check the To o ls->Bo ard menu, you should
see the three new entries for Trinket and Gemma:
