   1. Controller: ESP-WROOM-02 (ESP-8266 core)
      modified StandardFirmataWiFi running
      connect to Raspberry Pi 3 WiFi access point
   2. LED-Driver: Adafruit HT16K33 (I2C interface)
   3. LED-Matrix: home made (built in a bottle)

      home made LED Matrix

3. Raspberry Pi 3

   1. Message handring: Node.js, Johnny-five, Twitter-API
   2. Wifi access point: hostapd running
   3. Local Control webpage
      message transfer to Bottled Circuit:  using johnny-five’s “sendstring” method
      I’m going to upload this system to Github as soon as possible.
