Monday night (Nov 10) I’ll be going over the I2C protocol and how to make it work for you. I2C is used in all sorts of sensors these days, and understanding how to make the AVR’s speak it is useful stuff!
I’ll bring in some I2C external memory chips, a temperature sensor, and a 3-axis accelerometer. [...]
In honor of Columbus Day, the AVR class took a night off from “formal” instruction and messed around with noisemakers. Specifically, using analog-to-digital conversion techniques to control the pitch of a square wave run through a small speaker. Hilarity ensued. (Follow along with us at the AVR Microcontroller Class Wiki Page.)
If you have signed up for the Programming Ruby classes, thanks! Â

Have you been writing code for so long that you just can’t stand to tell the compiler what it should already know? Do you want to learn how to free yourself from the semicolon, the brace, and the parentheses? Do you want to  extend your program, by adding new code, by extending objects and definitions, or [...]
16 AVR programmer kits walked into a room in anti-static bags last night. 16 fully assembled and tested programmers walked out. Many people learned to solder and the sweet smell of flux filled the air. It doesn’t get better than that.
Except that next week, it will.
Special thanks to Mitch for the cool demos, soldering coaching, [...]

So you’ve got this great new idea, but it requires a computer.. The
blasted thing just doesn’t do what you need it to do out of the box.
You’ve got a few options: you can give up on your [...]
