You should solder your comonents like below schematic:
But you can also send my custom PCB gerber files to PCB factory which is at PCB/LED Board Gerber.
Then, layout your ping pong balls like below:

There are three methods to control your LED board:
- Buttons
- Android App
- Web UI
| Button | Function |
|---|---|
| Button1 | Turn LED ON/OFF |
| Button2 | Set Background Palette |
| Button3 | Previous Display Mode |

You can also contorl your board through WIFI.
Because this LED Board is put in our office, so I use STAION mode to let it connect to our office's router.
In order to easily access it, I change it's hostname to ledboard, so I can access it through http://ledboard.
This Web UI use websockets, so the board's data are Synchronized to all clients.
