Summary and Background Knowledge
The most popular example of a Squishy Circuits
microprocessor project is Squishy Sound. Squishy Sound uses
the conductive dough to change the pitch of a speaker – the
higher the resistance, the higher the pitch.
Materials:
o
Computer with Arduino Software
o
Arduino Uno Board (or similar)
o
Conductive Dough
o
Speaker (the piezoelectric buzzer sold on our website
does NOT work for Squishy Sound)
o
Breadboard
o
470 Ohm Resistors (or close)
o
Wire
