Turn on/off 4 lights using 4 physical buttons and blynk

dilldar · May 4, 2018, 6:37pm

hello dear friends
i copy blynk example for sync physical button and modify according to my project.now i am having a problem that 2 physical buttons works well and also sync with blynk app but other 2 physical buttons dose’not work …but app switch works well…
please help me. here is code which i use.
suggestions will appreciated in advance.

You only need

timer.setInterval(100L, checkPhysicalButton);

once in your setup()

Also remove the brackets around all of these, they are not needed

{ pinMode(ledPin1, OUTPUT);
  pinMode(btnPin1, INPUT_PULLUP);
  digitalWrite(ledPin1, led1State);
  timer.setInterval(100L, checkPhysicalButton);}

 { pinMode(ledPin2, OUTPUT);
  pinMode(btnPin2, INPUT_PULLUP);
  digitalWrite(ledPin2, led2State);
  timer.setInterval(100L, checkPhysicalButton);}
{
  pinMode(ledPin3, OUTPUT);
  pinMode(btnPin3, INPUT_PULLUP);
  digitalWrite(ledPin3, led3State);
  timer.setInterval(100L, checkPhysicalButton);}

 { pinMode(ledPin4, OUTPUT);
  pinMode(btnPin4, INPUT_PULLUP);
  digitalWrite(ledPin4, led4State);

  // Setup a function to be called every 100 ms
  timer.setInterval(100L, checkPhysicalButton);}
}

Toro_Blanco · May 4, 2018, 6:50pm

You setup() should look like this

void setup()
{
  // Debug console
  Serial.begin(9600);

  Blynk.begin(auth, ssid, pass);
  // 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);

  pinMode(ledPin1, OUTPUT);
  pinMode(btnPin1, INPUT_PULLUP);
  digitalWrite(ledPin1, led1State);
 

   pinMode(ledPin2, OUTPUT);
  pinMode(btnPin2, INPUT_PULLUP);
  digitalWrite(ledPin2, led2State);
  
  pinMode(ledPin3, OUTPUT);
  pinMode(btnPin3, INPUT_PULLUP);
  digitalWrite(ledPin3, led3State);
 
  pinMode(ledPin4, OUTPUT);
  pinMode(btnPin4, INPUT_PULLUP);
  digitalWrite(ledPin4, led4State);

  // Setup a function to be called every 100 ms
  timer.setInterval(100L, checkPhysicalButton);
}

i change the code as you said dear but problem remains.
led1,led2 and btn1,btn2 works fine both physical and blynk.

I guess you’re using an ESP8266-12. I suggest to use these pins: 10, 4, 16, 12, 15, 5, 13, 14. Pin 2 is the onboard LED.

dilldar · May 4, 2018, 7:40pm

dosent work dear

/ Set your LED and physical button pins here
const int ledPin1 = 12;
const int ledPin2 = 13;
const int ledPin3 = 14;
const int ledPin4 = 15;
const int btnPin1 = 5;
const int btnPin2 = 4;
const int btnPin3 = 10;
const int btnPin4 = 16;

Toro_Blanco · May 4, 2018, 7:44pm

Hmmm, the code looks good. Unless there is something I am overlooking.

Maybe try increasing the timer interval, perhaps the timer is restarting the routine before it has time to reach those parts of the code. I am not certain this is the issue as I have done almost this exact same thing (expanding example to 4 buttons and relay) before and did not have any issues.

I will have to dig and see if I can find my old code to compare.

dilldar · May 4, 2018, 7:47pm

thanks for helping me…
can’t understand 2 buttons works fine and other 2 are not working.

Emilio · May 4, 2018, 8:20pm

switch 'em around and see if the problem moves

Check this…
and this fyi

Toro_Blanco · May 4, 2018, 8:42pm

Just to be clear in case other users read this post.

Was the solution to increase the timer interval? or was it something else?

dilldar · May 4, 2018, 8:59pm

No its not timer interval.
by changing the pins it works fine
i replace pin 0(D3) to 1(TX) and pin 2(D4) to 9(S3) and it start working.

const int ledPin1 = 12;
const int ledPin2 = 13;
const int ledPin3 = 14;
const int ledPin4 = 15;
const int btnPin1 = 5;
const int btnPin2 = 4;
const int btnPin3 = 9;
const int btnPin4 = 1;

Toro_Blanco · May 4, 2018, 9:12pm

But the code you posted last also has the timer interval increased from .1 Seconds to .5 Seconds. Just to confirm it works with the timer interval at 100L as well?

dilldar · May 4, 2018, 9:20pm

yes it works with time interval 100L and woks brtter than 500L .by using 500L it lag little.

dilldar · May 5, 2018, 3:58am

dear @Emilio i think that is pretty simple for only wifi ssid and pass. not for blynk token.
your code is pretty good also for token+wifi ssid and pass.

here is code for 4 channel with physical button and blynk.
thanks a lot for helping.your idea of changing pins works for me.
