Delay when turning off pins

Need Help With My Project
1

Hello, guys! My project is to control two relays, V10 and V11. I dont know why, but when I turn off the pins, either they are virtual ou digital on the app, there’s a delay of 5 seconds, which is the timer for one function. To turn on, it is instantly.
And it happens randomly too. Yesterday I had delay in both pins, now only one of them take time to turn off.

I dont know if its power related, because when the plate is connected to the USB, it works normally. I use a MB102 breadboard power supply. 5V to the relays and 3.3V to the NodeMCU and the sensors.

Here’s the code

    /* PORTAS EM USO

This is the part I use to turn them on or off:

     BLYNK_WRITE(V10) {
          digitalWrite(D0, param.asInt());
        }
        BLYNK_WRITE(V11) {
          digitalWrite(D1, param.asInt());

I have tried using them directly as digital pins on the app, but the problem still happens.
Just for you to know, today it’s working normally, but probably it wont anytime

Thanks

another thing:
I’m having conflict with the 2 function timers. For this code 10000 and 1200000, the clock display works fine, but the sensor is never read

I changed it to 5000 and 5000 and it’s kind of bugged.

The only way it works fine is 1000 on clock and 5000 on sensor (DHT11 sensor btw).

3

When you use 5000 for both function it may not be able to do both at the same time, therefore buggy, I’d use slightly different times.

And regarding the first issue I’m not sure if I understood what is happening.

4

it’s kind of simple: my relay pins, either if i use them virtual as usual or if I change to digital, sometimes in the day, have a delay to turn off.
I press the button on app, the relay light turns off, but only in like 5secs (which is the timer for one function), the relay makes the noies and the led I use to check them turn off.
It’s completely random. Sometimes restarting the NodeMCU solves the problem, sometimes not, or sometimes, like now, it’s working perctly.

As the second issue, I have tried using very different numbers to the timer, but it only works good (checking by serial monitor) when sensor is like 5000 and clock 1000

No more help? :frowning:

It looks like you did not call “sensorPalma” function in this code. In timer attach side, its commented. My suggest, translate your code to English. I am doing like that to get help for my issues.

I have really good internet connection. Sometimes i have about 3 seconds latency problems. I think it is normal.

Try to call your relay control function with timers. May be function depends some if else statement now.

(I felt lazy to read all code without comments :smile: try translated code )

7

The sensorPalma is for a ClapSensor function, to turn the lights. I dont even use it in this project at all.

8

This problem still happens :frowning:

Is this project on a breadboard? if so then you cant really expect to get reliable long term results as the resistance between the breadboard sockets and the devices and wires you have plugged into them will cause erratic behaviour.
It also seems that you have doubts about your power supply. Have you tried a beefed-up power supply?

It’s very difficult for people to help you when your code is cluttered-up with unused functions and your comments and variable names aren’t in English. It’s also very difficult to diagnose random problems, especially if you don’t supply serial print data that relates to the point in time when the random event occurred.

I’d put money on the fact that this behaviour isn’t being caused by Blynk so it really fits into the category of something that only you can sort-out by simplifying your code then monitoring these random disconnections and looking for a pattern.

had to delete because i forgot to delete the auth part

Hey pete!

So the problem that still persists is the incompatibility between the RTC function and the DHT 11 sensor reading function.
When I have the RTC running, the sensor only works with some values of the timer, like when the RTC is 5000 and the sensor function is 12000

void loop() {
    Blynk.run(); 
    timer.run();                 
}

The timer part:

timer.setInterval(12000L, sendSensor);    // dht sensor 
timer.setInterval(10000L, clockDisplay);  // rtc 
timer.setInterval(300L, somefunction);   // relay function

The sensor part:

void sendSensor()
{
  float h = dht.readHumidity();
  float t = dht.readTemperature(); // (true) para Fahrenheit

  if (isnan(h) || isnan(t)) {
    Serial.println("Falha ao ler sensor DHT11!"); // "failed to read dht11 sensor
    return;
  }
  Blynk.virtualWrite(V5, h);
  Blynk.virtualWrite(V6, t);

  Serial.println("\n");
  Serial.print("Temperatura: ");
  Serial.print(t);
  Serial.println("C");

  Serial.print("Umidade: ");
  Serial.print(h);
  Serial.println("%");

So when I put random values on the timer, this happens:
The dht sensor is not read

So is that your only problem.

Yes. I have an IR problem but it is discussed in another topic.
