As i said before, i am using clear BlynkBlink example sketch:
// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth = "DoesNotMatter";
// Your WiFi credentials.
// Set password to "" for open networks.
char ssid = "DoesNotMatter";
char pass = "DoesNotMatter";
// Debug console
Blynk.begin(auth, ssid, pass, IPAddress(DoesNotMatter), 8080);
// You can also specify server:
//Blynk.begin(auth, ssid, pass, "blynk-cloud.com", 8442);
//Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8442);
// You can inject your own code or combine it with other sketches.
// Check other examples on how to communicate with Blynk. Remember
// to avoid delay() function!
Also, did i mentioned, that if i use sliders instead of zeRGBa, It is working fine? Anyway it is on the video, so… you could saw it. Pins on the video, I using, is: D5,D6,D7,D8… D7 acts like GND, so other pins is not inverted. Range is correct. And yes, it was working few days ago, like a charm.
