After [elyob] read about CheerLights on Twitter, they decided to join the project. They had some LED strips, microcontrollers, and some time to build a way to light up their sports poster with the latest CheerLights color.
I love to see how fast people can join the CheerLights project and build something new with what they have. I asked them on Twitter about some more details. [elyob] is using an ESP8266 microcontroller running ESPHome connected to some NeoPixel light strips. They use Node-RED to connect to the CheerLights MQTT server to get the latest color.
