Trying to add a physical push button for ON/OFF

Madhukesh · January 2, 2019, 10:50am

Hello !

I am trying to give a light tweak to this project by adding a physical push button for ON/OFF which is
V2 virtual pin in the code below. I am using the blynk sync state push button code and trying to integrate with this. But am not able to get it work. I clearly understand this is not Blynk problem or no one is here to help anyone. But i wanted to know whether my idea will even work or am going on the right path. Please guide me or please give a piece of code which i can inject and get it working…


BLYNK_WRITE(V2)  // ON-OFF Manual 
{
    if (param.asInt()==1) {  // boton encendido  
    terminal.println();
    terminal.println();
    terminal.println();
    terminal.println("Manual MODE is ON");
    terminal.println("Press ON/OFF button if required");
    terminal.println("Device is ON");
    terminal.println();
    terminal.println();
    terminal.flush();
    
        if (manual==0){  //está en modo automático     
         checklastbuttonpressed ();
         manual=1;
         mondayfriday=0;
         saturdaysunday=0;
         alldays=0;

         digitalWrite(TestLED, HIGH); // set LED ON 
         Blynk.virtualWrite(V2, 1);   //Turn ON Button Widget

That doesn’t make much sense!
If you’re using a physical button as opposed to a widget in the app then that physical button needs to be connected to one of the GPIO pins on your MCU.
The other side of the physical button will be connected to either Ground or 3.3/5v (Vcc) depending on your device, and your preference as to whether you want to pull the pin LOW or HIGH when the button is pressed.

You’ll need to declare that GPIO as an input with a pinmode statement and either monitor it for a change of state or attach an interrupt to it.
I’d also suggest using some denounce code on the physical button, as most switches don’t give a clean transition from off to on, you frequently get ‘noise’ that needs to be cleaned-up to get a consistent switch operation.

Also, posting snippets of code, and no details of the hardware that you’re using makes it difficult to help point you in the right direction.

Make yourself a timed function to detect a physical button state 0/1
http://docs.blynk.cc/#blynk-firmware-blynktimer
https://www.arduino.cc/reference/en/language/functions/digital-io/digitalread/

Following the debouncing suggestion as mentioned by @PeteKnight
https://www.google.com/search?q=arduino+button+debounce

Either use a switch or add in some latching code to toggle between 0 & 1 each press - I will leave that for you to Google. Then use it to send a matching 1/0 state to V2
http://docs.blynk.cc/#blynk-firmware-virtual-pins-control-blynkvirtualwritevpin-value

And follow that with a sync command to act as if the App button was pressed instead

PS, I changed your title to something a bit more meaningful

sorry for the incomplete info.
Yes i have attached a Push Button to Pin D1 and the relay out to pin D2 , And am using node mcu and also defined them in the code

const int TacSwitch1 = D1;
const int TestLED11 = D2;
void checkPhysicalButton();
int ledState = LOW;
int btnState = HIGH;
void setup()
{
  pinMode(TestLED1, OUTPUT);          // Pin D2 P5 on board
  pinMode(TacSwitch1, INPUT_PULLUP);  // Pin D1 P1 on board
  
  digitalWrite(TestLED1, LOW); // set LED OFF
  digitalWrite(TacSwitch1, ledState);

this is just a few lines of the code so state that push button is defined.
later what i have done is in the setup part,

void checkPhysicalButton()
{
  if (digitalRead(TestLED1) == LOW) {
    // btnState is used to avoid sequential toggles
    if (btnState != LOW) {

      // Toggle LED state
      ledState = !ledState;
      digitalWrite(TacSwitch1, ledState);

      // Update Button Widget
      Blynk.virtualWrite(V2, ledState);
    }
    btnState = LOW;
  } else {
    btnState = HIGH;
  }
}

BLYNK_WRITE(V2)  // ON-OFF Manual 
{
    if (ledState = param.asInt()) {              //// here am missing out 
       
    //(param.asInt()==1)   // boton encendido   //////// this was how it was previously done
    terminal.println();
    terminal.println();
    terminal.println();
    terminal.println("Manual MODE is ON");
    terminal.println("Press ON/OFF button if required");
    terminal.println("Device is ON");
    terminal.println();
    terminal.println();
    terminal.flush();
    digitalWrite(TacSwitch1, ledState);
    
        if (manual==0){  //está en modo automático     
         checklastbuttonpressed ();
         manual=1;

         Blynk.virtualWrite(V2, 0);   //Turn OFF Button Widget
         }  
         }
}

hardware part is completely working fine. The only problem is the code part.

and posting the complete edited code is not a problem. but it goes way too long. above i have mentioned the bits of code that i have injected to the @psoro code.
And below i will post the whole code .

triggering the V2 that is the on/off button widget will bring the program into manual mode and work untill we choose auto in the Blynk app. Thats the end game. Because physical button comes in handy.

PeteKnight · January 2, 2019, 2:01pm

You’re declaring the checkPhysicalButton function here, in your declaration section, and later as a proper function.

Pete.

Madhukesh · January 2, 2019, 2:19pm

Actually i got this working in the following way
Lets assume the program is running in manual mode
Then when ever we press the physical button it will work without a problem.
But when the program is running in say mon to fri or sat to sun or anyother auto mode
And then when when i turn on the with the physical button then it will turn back off after 10 sec .

Can you please give me some clue how to get this right. I know we cannot ask any help here. But after googling and some research am asking for help here. And btw am not having any background from software part. Am a tool and die maker.

Costas · January 2, 2019, 4:50pm

@Madhukesh I don’t remember now how much was written by @psoro , by you and by me but here goes.

The sketch has an integer flag called manual (0 off and 1 on) .
If you incorporate this into the checkPhysicalButton() function you could then just change the first line of the activetoday() function from:

if(year() != 1970){

to:

if((year() != 1970) && (manual == 0)){ // i.e. NOT in manual mode

Costas · January 2, 2019, 5:27pm

Keep the questions to the forum.
manual 0 or 1 goes in physical button section and the existing if(year… line in the sketch is changed to the new version.

Madhukesh · January 4, 2019, 12:54pm

@Costas Am not saying that he owns the code or he alone has done with the code. I know that you have also contributed to the code. My intention was to say that which code i am about to edit and add some extra feature or something new. Thats it…

coming to the new version of

this will keep the terminal in the app blank. will not give any sought of update about the mode selected.
I will try something else. If i get that working i will update here.
Thank you for the idea.

Costas · January 4, 2019, 1:00pm

Neither was I. I was simply saying I can’t remember too much about the code and I’m not going to spend hours looking through it, that’s your job.

Not sure what the terminal is. I did think afterwards that using the “manual” variable is perhaps not a good idea as it might interfere with other parts of the sketch. Perhaps use a variable of “manualButton” in checkPhysicalButton() function and the if(year....)

Madhukesh · January 4, 2019, 6:02pm

yeah i know…

i will try out. Thank you.

Toro_Blanco · January 4, 2019, 8:27pm

without looking through all of the code/links, here are a few things I spotted wrong with your posted code snipets.

In void checkPhysicalButton()

  if (digitalRead(TestLED1) == LOW)

should probably be

 if (digitalRead(TacSwitch1) == LOW)

as this is the actual button/Input.

Also,

digitalWrite(TacSwitch1, ledState);

should probably be

digitalWrite(TestLED1, ledState);

as this is the output/led/relay

Toro_Blanco · January 4, 2019, 8:58pm

Additionally, void checkPhysicalButton() will not make the BLYNK_WRITE(V2) function run. You would need to add Blynk.syncVirtual(V2);

I would also change the if statement BLYNK_WRITE(V2) function back to how it was (as mentioned in your comments in the code).

void checkPhysicalButton()
{
  if (digitalRead(TacSwitch1) == LOW) {
    // btnState is used to avoid sequential toggles
    if (btnState != LOW) {

      // Toggle LED state
      ledState = !ledState;
      digitalWrite(TestLED1, ledState);

      // Update Button Widget
      Blynk.virtualWrite(V2, ledState);
      Blynk.syncVirtual(V2);
    }
    btnState = LOW;
  } else {
    btnState = HIGH;
  }
}

BLYNK_WRITE(V2)  // ON-OFF Manual 
{
    if (param.asInt()==1) {

Yeah i tried that out earlier. But it doesnt come in sync with the push button.
Lets say in app we turn on and later when we try to switch it off with push button, it takes 2 clicks to turn it off. But there is no sync issue on the app. Which ever the earlier state was in the push button ,the app works fine.

And is there any way or widget , that lets us control a gadget at a particular time in a day, and twice or more in the same day ? Ex. Mon - 10.00 Am to 11.00 Am and again 4.00 Pm to 5.00 Pm ?
