Unfortunately not USB powered though. [pocmloc, Sep 25 2023]

The whole thing - CircuitPlayground Express https://learn.adafr...nd-express/overview
10 three-colored LEDs, PWM control by microcontroller, has a light sensor, motion sensor, temperature sensor, sound sensor, places to hook up all the other sensors we don't have, powered thru an old-fashioned USB micro connector. $25 bucks. If it won't do what you want, you didn't program it right. [lurch, Sep 25 2023]

This is probably do-able, but I'm not sure what the advantage of it would be

It's one giant pixel with its three colors and dimness, used as a lamp. The advantage is a lamp which shines in any of 16 million colors or 25,000 degrees of brightness. Want an off-burgandy in "ow my eyes" brightness? you can have it! (With the Voiceco companion power pack, sold seperately)

Welcome to the HalfBakery, [jojo99]. Let us know what you have been doing with your life for the past couple of decades. Are you involved with USB development? How do you imagine USB technologies developing over the next 20 years?
