Ledstring time and colors are sometimes changing to a bogus value.
(Communication between Arduino and ESP is not stable)

rein commented 5 days ago

Problem:
Serial data is sent correctly by ESP but is not always the same as data received by Arduino.

Caused by:
The Arduino is working with 5V and the ESP is working with 3.5V.
A diode is place beween Esp (TX) and Arduino (RX) to make sure the Arduino cannot blow-up the ESP due to different voltage levels.
Maybe this diode is not the right value or a proper solution at all.

Solution:
We have to research a more reliable solution. There are multiple options:
-Use a standard level converter
-Use a better diode
-Use something else
