Biodata Sonification Diapj

This document provides a circuit diagram for a MIDI controller that uses a 555 timer chip and Arduino 328p microcontroller. The 555 timer chip generates pulses that are sent to the Arduino's input pin to be interpreted as MIDI notes. Additional components include decoupling capacitors, a potentiometer to control voltage, and an LED for output. Notes provide information on component values and connections between the chips.
