/* LITTLEBITS PING))) THEREMIN

   This sketch reads a PING))) ultrasonic rangefinder and returns the
   distance to the closest object in range. To do this, it sends a pulse
   to the sensor to initiate a reading, then listens for a pulse
   to return.  The length of the returning pulse is proportional to
   the distance of the object from the sensor.

   The circuit:
* +V connection of the PING))) attached to +5V = PROTO bit IN left
* GND connection of the PING))) attached to ground = PROTO bit IN middle
* SIG connection of the PING))) attached to digital pin 1 =  PROTO bit IN right

Arduino d1 <= Proto <= Ping)))
Arduino d0 <= Power
Arduino a1 <= Slide dimmer
Arduino d9 (analog) => Number => Oscillator => Synth Speaker

Experiment with more oscillators, filters, sequencer, other input sensors instead of the slider etc...!
 

Duration: 10 minutes, including coding (copy/paste)
