Story

This video is going to be the first in a series of multi-part videos.

Part 1 would mostly consist of equipment and initial code testing.

I'm planning on improving/adding features or functions to this project and the videos for those would be uploaded in the following weeks.

As of now, I'm still waiting for the replacement parts from China and I think it would take a long time before I receive it, because of the Corona Virus/COVID-19 stuff.

I've been planning on making this since 2018 and I have actually recorded the videos for it already, but since I have just upgraded my camera last 2019, I thought that it would be weird to upload a video that has lower quality.

Encountered a problem related to the library as well, but I have managed to fix it.

On this project, I would use an ArduinoNANO board, an 8x8 WS2812B RGB LED Matrix and a PS2JoystickModule.
