ftcSoundBar is a sound card for Arduino, ftDuino and fischertechnik TXT/TX-Controllers based on an espressif LyraT board.
It has multiple connectors, so you could use it in various configurations:
- wifi based WEB-UI
- wifi based RESTAPI
- I2C-bus Interface
Please checkout the ftcSoundBar wiki and the article about ftcSoundBar in ft:pedia 4/2020.
With firmware version V1.2 the I²C-interface was implemented in the ftcSoundBar's firmware. To get the interface running, the cabling of your ftcSoundBar board differs from the description in the ft:pedia article. Please refer to "Build your own ftcSoundBar" for correct cabling.
