Imagine you wanted an LED light to turn on when you open one of your cabinets…that would light just the contents of that cabinet…with a very small strip of LED lights…like 5 or 10 individual leds.
Is it possible to use a wemos d1 or other esp8266 device to not only control on/off, but power the lights as well from the 5V USB plug attached to the D1 Mini?
I would normally use a 12V power adapter to provide juice to the LED and the D1 (stepping down the power) then run data to the LED…but…
in this case, I’m using non addressable white LED’s with only a + and - connection.
