Step 5: Connect Remaining Components

Picture of Connect Remaining Components
Once your input and output circuits are made on your perf board, place it inside and start attaching all the wires that have yet to be attached.

  • The audio input goes into the input circuit, then into the Arduino's analog inputs
  • The pot taps go to the Arduino's analog inputs
  • Two LEDs go to PWM outputs, one goes to a digital output
  • Four PWM outputs go into the 8/2-bit weighted DAC circuit
  • The output of the weighted DAC circuit goes to the audio output
