Here are a couple of pictures of my latest toy, the Arduino Duemilanove microcontroller. It's equipped with 16K flash memory, 1K SRAM and 0.5K EEPROM and is currently sitting on my desk, flashing out "hello world" in Morse Code. The processor is an Atmel ATMega168 running at 16MHz.
Now I just need to learn the assembly language so I can implement something useful :-)
