Hi :slight_smile:

It's Christmas Time well I thought it's good to decorate a room with this interactive frame :slight_smile:

How it works:

  • AI A6 GSM module receives SMS and sends it to Arduino Uno as a master (i2c bus).
  • Arduino Uno sends by i2c bus info to Arduino Nano to start to move servos, and to another Nano to play a music.
  • Arduino Nano, which plays a music, sets high state on PIN 2, and module ISD1820 starts to play a previously recorded song.
