A micro-controller based synthesizer leveraging the Web Serial API.
This project allows for generation of two oscillating signals. Each signal can be modified through nodes as exposed by the ´Web Audio´ API. Operations can be applied via dedicated knob inputs on a micro-controller. The resulting signals are them combined and audible via your speakers.

The circuit is based on the Arduino UNO. You will need the following components:
- Switch => https://www.digikey.at/en/products/detail/cit-relay-and-switch/ANT11SECQE/12503336
- PCB => https://www.digikey.at/en/products/detail/adafruit-industries-llc/4786/13617527
- Potentiometer => https://www.digikey.at/en/products/detail/bourns-inc/PDB12-H4301-103BF/3780664
- Resistors => https://www.digikey.at/en/products/detail/stackpole-electronics-inc/CF18JT220K/1741641
- Jumper Wires => https://www.digikey.at/en/products/detail/sparkfun-electronics/PRT-12795/5993860
- Any microcontroller compatible with Arduino Uno
Switch x2, PCB x1 (bundle of 3 with the link above), Potentiometer x6, Resistors x6, Microcontroller x1, Wires - 20-30 single wires
After assembling the circuit, connect the Arduino to your computer via USB.
Clone the repository to your local machine. You will need to install the Arduino IDE to compile and upload the code to your micro-controller. You can download the IDE here: https://www.arduino.cc/en/software
After installing the IDE, open the project in the IDE, open the sketch in "./sketch/arduino" and click "Upload" to compile and upload the code to your micro-controller. The micro-controller will now be ready to use.
Run npm install to install the required dependencies.
Run npm run dev to start the application.
Connect your micro controller via usb and click "connect". The application will automatically detect the port and connect to it.
Happy synthesizing!
