in Arduino
I missed the arduino miniconf in 2010, but I was able to buy the pebble shield from a former participant, along with an arduino mega board. This board was a bit better for me to first learn on than the mobsendat because it had more interactive I/O to play with (potentiometer, LDR, LEDs, LCD display, and more).
This gave me a chance to learn the Aiko framework from Andy Gelme, which allows for registering event handlers that get called at a specified interval. I ended up writing some handlers that were missing, like a button handler that calculates which combination of buttons is pressed from the combined resistance generated by the 3 buttons. I used this to tell the board at what frequency to flash an led based on potentiometer or LDR light input.
slightly improved version with LEDs connected to the relays
