The Chinese “Wemos D1” Clone I bought from SEG in china was a perfect choice for this project due to its deep integration in to the Arduino ecosystem i.e. its layout being the same as the “Arduino Uno” which allows compatibility with the wide range of available "Shields".
The LED Screen
The LED screen is an “Adafruit NeoPixel Shield” which was designed around the “Arduino Uno” form factor which the “Wemos D1” clone used in this project shares. The screen consists of 40 WS2812B (NeoPixel) LEDs. These are RGB LEDs which are addressable over a 3 wire interface meaning we can control each led independently of the others.
