excellent explanation, I hope to learn quickly to develop this same project, but using the new BLYNK 2.0 platform. I appreciate your teaching and comments regarding the use of the new platform, which is too structured.

Hi sir... Thanks for your explanation. It's clear & I wanna ask, I try to get data from server with code below, but server didn't response to sent request value on V0, so what the problem? BLYNK_CONNECTED() { Blynk.syncVirtual(V0); // will cause BLYNK_WRITE(V0) to be executed } BLYNK_WRITE(V0){ int pinValue = param.asInt(); Serial.print('0' + String(pinValue)); delay(10); }

so sorry you wasted your time, with this info, looked very good however, the app is IOT and it is crap, -so crap i, and the app is far too geeky to operate, dont use it it does not allow you to even delete a template, its absolute rubbish
