Seeking Guidance for Hyperion Project with PC and TV using ESP8266 D1 Mini

I achieved what you are trying to achieve with an arduino nano
lookup a project called adalight and prismatik

prismatik runs on pc
after you have configured # leds and data pin for Leds , flash to arduino
config prismatik for com port and # leds and orientation of leds good to go

or use WLED like here
