Hello all. Brand new here, and just got my first project up and running on my esp8266 running last night, and of course, I went and broke it. What I’ve got is a large 3d printed six digit 7 segment clock that displays hours, minutes, seconds using neopixels. It is controlled via an esp8266 running Micropython.
I would like to be able to control the color of my neopixels with the zeRGBa slider on the Blynk app, but I am kind of lost as to how to get it to connect, or control.
I can not even get the program to connect to the Blynk app.
The code below is the working code with some of the Blynk stuff added. Any help would be appreciated.
