JLCPCB Prototype for $2(Any Color): https://jlcpcb.com

We have seen many LED matrix scrolling display projects. Some of them have hard code sentence burned in the code while some of the displays are Bluetooth enabled. But I took this concept to the next level with much smaller size(around the size of a TV remote), much wider coverage area (almost from anywhere in the world) and much much convenient way of changing the message on it(just say Ok Google, display on the board No Pain No Gain & your task is done).

Watch this video to know how to make it.
