For those following along at home: The Chronotune’s user interface is a rotary encoder, read by the Arduino. Year is indicated on 7-segment displays, and audio files are handled by a uMP3 board. (That’s what we had sitting around. If we had it to do again, we’d use an mp3 shield.) The speaker is driven by an LM386. The dial is moved by a stepper motor from an inkjet printer, with an EasyDriver.
Anyone tinkering with the Arduino experimenter’s platform is welcome to attend, as are those who are curious but don’t know where to begin. We’ll also have a look at the Arduino-LabVIEW bundle recently offered by Sparkfun. Things get under-way this Thursday (12/8) at 7pm.
