Lo-fi Arduino Guitar Pedal

Step 5 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
