Objective: I upgraded a market-purchased LED billboard so that the display can be controlled through a website. The use of this billboard was for commercial marketing advertisement, live sports scores, etc.

Approach:  I added an ESP8266 microcontroller that receives JSON data from a server through a Wifi network. The server could control the duration, loop duration, etc. of whatever is being displayed on the boards. I wrote code for the microcontroller to extract information from the server and control the  LED board according to the user’s input through the website. I then figured out the power supply connection and wiring in order to connect this controller to the existing LED Billboard hardware.
