- Quick taste of programming/communication (est 15-20 min)
- Phase 1: Flash (human->computer)
- Vertically tiled sections for each instrument (including flutophone)
- Divides into beats, puts actions in array
- Each instrument as a number (0-3), and each note has a letter (A-X, Z=rest)
- Every beat (variable bpm) Flash sends an encoded serial output
- Example ~0A~1Z~2C~3Z
- Bassbot plays a hit, snare rests, xylophone plays 3rd lowest note, flutophone rests
- Phase 2: Serial (computer->master)
- Arduino master in a constant cycle
- if it sees a ~ in serial, it looks at the intrument code, then sends it a play signal
- Phase 3: Digital in/out (master->slave)
- Master->Drumset
- Two input pins (play bass, play snare)
- Constant cycle looking for a signal on those pins
- if it sees play bass it does the neccesary solenoid valve manipulations
- if it sees play snare it activates the solenoid on the side that was not most recently played
- Master->Xylobot
- 4-bit binary encoding of note is always sent(only white keys)
- 1 "hit" signal, which tells the xylobot to play
- xylobot board decodes the current binary input when it sees a hit signal, then outputs to that solenoid
- Flaws:
- Timing from flash is sketch
- Chords are impossible
- there is no forthought: eg bassbot cant react to knowing it has a beat coming up.
- Flash is difficult to get to serial (we use serproxy to turn xml into serial)
- Flash code is poorly written and not easily expandable
