This section gives some basic electronics and robotics information along with helpful links. I also detail a lot of my projects. For most of them I've included schematics. I use ExpressSCH for drawing them and ExpressPCB for designing circuit boards. They are a free package from expresspcb.com. You can download for free and get your boards professionally manufactured for very reasonable prices. Of course, with the final layout you can also etch your own boards at home if you choose.

My First Microcontroller Project
I have plans to build several animatronic Halloween props, so I began looking into microcontrollers to run them. I want with Atmel due to their availability, functionality and popularity. This is a very simple initial project to ensure that I'm off on the right foot. Being on a MAC, I had to do a little more looking for a good programming platform, but settled on Eclipse. I'm using a USBtiny ISP for programming, with my code written in C. I won't go through all the details of setup, but if you're interested, there is an excellent article here.
Here is the code for this simple project which utilizes an ATTINY13 chip to blink an LED at 1Hz:
