This is a synthesizer based off the OctoSynth tutorial.

Materials Needed:

Arduino Uno
USB Cable to connect Arduino to computer
Soldering Gun
Large thin copper sheet
Small speaker
2 small four-sided baskets
Foam to cut
Static resistance plastic
9 volt battery
Battery connecter
Toggle switch
Electrical Tape
Hot glue gun (optional)
This code

Step 1: Testing the Code

Plug in test wires to the Arduino Uno, A0, A1, A2, A3, A4, A5, -6, 7

Plug in the black wire of the speaker into GND, and the red wire into 11

Connect the Arduino Uno to a computer using the USB cord

Open up the Arduino software (it can be downloaded for free at Arduino.com)

Paste in the OctoSynth code

Run the software and test to see if all the wires make noise

*Don't touch any of the touch points until after it runs through its musical sequence, which is very short*

<p>I really like the idea of using copper plate as contact switches. Well done.</p>
