Description:
Following Gian Pablo's lead, this is an Arduino-controlled AD5206 digital potentiometer controlling the frequency and amplitude of a 74H14 Schmidt Trigger oscillator, fed into an LM386 op amp.nnGian Pablo's guide:nhttp://itp.nyu.edu/~gpv206/2007/10/generating_polyphonic_sound_wi_1.htmlnnAD5206 tutorial:nhttp://www.arduino.cc/en/Tutorial/SPIDigitalPot

Reading the analog inputs and converting the random linear voltage readings from the aerials makes for interesting sounds when converted to tones either through straight PWM conversion or via the tone() function. Then mix in a homemade PT2399 delay pedal and run it through a homemade LM386 cigar box amp head powering a Weber signature series speaker.")
