WebJack-Firmata is a transport layer for Firmata.js and is based on WebJack, a JavaScript library that uses an audio modem to communicate with an Arduino µC via headphone jack. Firmata is a RPC like protocol, that defines a serial interface to read from or write to a microcontroller's pins. This demo allows web browsers to control an Arduino via headphone jack.
To run the demo, upload this modified version of the StandardFirmata sketch. You will also need additional hardware.
