IntroAVNET invited me to the "electronica 2018" in Munich to hold a speech about IoT and Neopixels. So I thought, wouldn't it be great if I could finish my speech with presenting a functional project on stage by controlling Neopixels with a smartphone. Something with a practical, everyday use in home automation? .... Yeah, I got it! A hat! Home automation at it's finest .. somehow.
Quite easy. We just need a pin for the Neopixels. Although the WeMos and the Neopixels are working with 5Volts, they can be both be powered by a 3.7V LiPo battery for a short period. To wrap the stipe around the hat once, I needed a total of 19 Neopixels (with a specification of 60 LEDs / meter).
