Problem debug?

1

I have this sketch that runs properly (almost) of one with Arduino Ethernet shield

void loop(){ Blynk.run(); signalLed(); } void signalLed(){ if (timeElapsed > interval){ for(int i=0; i<index; i++){ stato[i] = digitalRead(pinR[i]); } if ((stato [0])== LOW){ led1.off(); }else{ led1.on(); } if ((stato [1])== LOW){ led2.off(); }else{ led2.on(); } if ((stato [2])== LOW){ led3.off(); }else{ led3.on(); } if ((stato [3])== LOW){ led4.off(); }else{ led4.on(); } timeElapsed = 0; } }

I have found that by feeding Arduino, just connected to the server, for a brief moment Led1 goes ON and then back to off. Because?
In the app I placed 4 buttons with switch function and the log is this

37345] Ready (ping: 33ms).

Why this?

where is the rest of your code?

No idea about it ?
Someone can help me?

Sorry, but it is really hard to know exactly what you are asking about?
Can you please be more specific?

Instead of making up your own timer, try the SimpleTimer library. It’s better to use with Blynk. The PushData example from the Blynk library has an excellent example of how to use it.
