imho spiest sich da was mit einem der Pins,
ich hab mal einfach alles auf Pin 5 gelegt, dann läuft es durch.

Mein Vorschlag wäre: hol dir ein LED Display, entweder ein MAX7219 (SPI) oder eins mit einem HT16K33 (I2C) braucht weniger Pins, und der ESP kann was anderes auch noch machen.
Edit:
int cPin = 9;
löst bei mir am NodeMCU einen WD Reset aus. eh klar, hätt' mir gleich auffallen können.
