What This Tutorial CoversThis tutorial is an expansion / continuation of the previous Bluetooth tutorial. In other words I will assume you are familiar with arduino and simple Bluetooth concepts. Also, I assume you know how to program an Attiny via arduino as an ISP or via a standalone programmer. I'm not going to be going over the code in detail unless it is something I didn't cover in the previous tutorial.
In this tutorial we will learn how to connect a Bluetooth module to an Attiny and how to make them talk! Exciting isint it? This will allow you to control a shrinkified arduino project wirelessly via Bluetooth from another arduino bluetooth enabled device, via a computer or even via a phone. In this tutorial I will cover how to control your Bluetooth enabled Attiny via a computer, but soon I will be doing a tutorial on how to accomplish this via an iPhone.
