[Solved] Help with LED in BLYNK App

Solved
1

Hello, how do I Blink LED Widget show the status of a pin on the Arduino Uno? High level or Low level?

2

Have you bothered to try any of the Blynk examples and if so what results did you get?

3

I tried, but I could not, the Widget LED LED 3 (V 3); can directly read the value of the pin? Or should first assign the value of the pin to a variable?

Paste in your formatted sketch and ensure it has plenty of comments so we can understand it.
The pins are virtual so Iā€™m not really sure what you mean about directly read the value of the pin.

Friend, as I did, I was trying here and put the value of the pin state in a Boolean variable and it worked!

define BLYNK_PRINT Serial
include SPI.h
include Ethernet.h
include BlynkSimpleEthernet.h

char auth[] = ā€œā€¦ā€;
WidgetLED led3(V3);
boolean estadoBotao;

void setup()
{
Blynk.begin(auth);
pinMode(7, INPUT_PULLUP);
}

void loop()
{

Blynk.run();
delay(500);
estadoBotao = digitalRead(7);

if (estadoBotao == HIGH){led3.on();}
else{led3.off();}

}

Glad you got it sorted but ensure sketches are formatted with the </> button as the one you posted leaves us guessing which libraries you are using.
