Hi Jordyn,

Unfortunately, wireless is not yet an easy task. The simplest implementation I’ve seen is ESP-NOW, that @Liam120347 Has looked into here:

> Hey all, I thought I would document my progress through this whole project on the forum so you all can see the progress and milestones. Backstory Like most other makers I like bright exciting stuff, enter the WS2812B, Neopixel, GlowBit, etc.. They go by many names, I have too many and want a centralised way to control them. This project will start from the idea that I've been brainstorming for a while and pull it all the way through to a PCB (hopefully - in 5 days; amongst some other project…

For something as simple as button pressing, I’d imagine that you could do the whole thing as just radios transmitting on different frequencies and demodulated into pins on the MCU, but this is outside my skill set for now. Maybe someone with more experience in the analog domain can chime in?
