Lightweight implementation of a DOTTI like device compatible with the Webbluetooth LED Display Demo and dotti-interfacing.
This device is in no way related to the original dotti. It instead implements only the interface expected by the Webbluetooth LED Display Demo. It's therefore probably incompatible with any other software meant to be used with the DOTTI.
The hardware is rather simple and cheap as it consists of an ESP32 develoment board and a 8x8 WS2812b RGB LED matrix display only. Both are connected using three wires:
- ESP32 VIN goes to V+ on the display
- ESP32 GND goes to V- on the display
- ESP32 D13 goes to IN on the display
The Arduino sketch requires the Adafruit NeoPixel ĺibrary which can be installed from within the Arduino IDE using the Arduino library manager.
