I just downloaded, saved and printed out my free cheat sheet. What a wonderful idea you have come up with! I printed out a copy of the one in the datasheet, but every time I look at it I get a headache.
A few years ago I discovered that my programming skills could be used to make real-world things move and flash and beep - I haven't looked back since! I love sharing what I've learned along this pretty bumpy (but very exciting) journey into the world of embedded systems - and that's why this website exists.
In addition to the website, I write a series for Nuts & Volts magazine that helps readers to move beyond the Arduino and into the world of AVR.
I'm a dad with a couple of energetic youngsters and a really cool wife!
