I’d like to build a largish number of led lanterns for an event that are WiFi enabled so they can flash, fade, strobe in sync (or in turn)
I’m thinking esp8266 is the way to go, but they need to be cheap, easy to build.
I was thinking of something like these strings
Ideally just adding the esp8266 between the battery and the led string, but then I’m restricted to the basic esp8266 modules - assuming they will fit through the neck of a wine bottle. I think the power supply is 3 coin type cells, so notionally 4.5v which is a bit too high to feed straight to the esp8266, so I’d need a voltage regulator, I assume.
Is this feasible?
Should I go for a bigger form factor controller and jam jars?
