This is my first Arduino project: a "noise box" synthesizer and step sequencer.
The basic features are
- 16-step programable sequencer with adjustable frequency and duration for each step
- synthesizer with 4 output waveforms (sine, square, triangle and sawtooth)
- noise generation (sirens, laser beam, random noise)
- special random sound modes
- blinky lights
All sound is generated using only the Arduino by PWM. More details and a video at http://mechomaniac.com/ArduinoNoiseBoxSynth
