change onPressAsToggle() state in button.h with code

Projects Programming
1

I'm using onPressAsToggle() with the button.h library. I have some momentary pushbutton switches I'm using and it's working pretty well. But under certain conditions I want to change the state of onPressAsToggle() with code. Essentially it would be as if I pressed the actual pushbutton. Anyone know how to do this?

I can't find that function in the button.h file available from the Playground. Where did you get button.h from ?
It would be helpful to see your full code and to know why you want/need to do what you describe.

I got the library from here: GitHub - carlynorama/Arduino-Library-Button: This is a library for adding buttons to Arduino projects. It supports events like OnPress and OnRelease.

I have 3 momentary pushbuttons controlling 3 things in a hot tub: On/Off for the hot tub, Air bubble pump, jets pump. There is a a small array, InputButtonsCurrentState[], that determines if any of these are on or off. For example, if InputButtonsCurrentState[BTN_HOT_TUB_ON_OFF] is HIGH, the hot tub is on. But if I want to turn the hot tub off with code (like if I get an error condition or something), I can't just go make InputButtonsCurrentState[BTN_HOT_TUB_ON_OFF] = LOW because the btnHotTub.onPressAsToggle() will just make it HIGH again. I need to toggle btnHotTub.onPressAsToggle(), but I don't know how.

My program is pretty large, but here's the parts that use the buttons

#include <Button.h>

//=== Push button Inputs ===
#define HOT_TUB_BUTTON_INPUT_PIN       53
#define JETS_BUTTON_INPUT_PIN          47
#define BUBBLER_BUTTON_INPUT_PIN       49

// Array for Input buttons, current state of hot tub, jets and bubbler
bool InputButtonsCurrentState[3];    
#define BTN_HOT_TUB_ON_OFF   0  // Hot tub On/Off Button
#define BTN_JETS_ON_OFF      1  // Jests On/Off Button
#define BTN_BUBBLER_ON_OFF   2  // Bubbler On/Off button


// Setup buttons.  Momentary push buttons are low when pressed
Button btnHotTub =  Button(HOT_TUB_BUTTON_INPUT_PIN, LOW);   
Button btnJets =    Button(JETS_BUTTON_INPUT_PIN,    LOW);
Button btnBubbler = Button(BUBBLER_BUTTON_INPUT_PIN, LOW);

void ReadInputButtons(){

  // Read button inputs 
  btnHotTub.listen();
  btnJets.listen();
  btnBubbler.listen();
    
  if (btnHotTub.onPressAsToggle()) 
  { InputButtonsCurrentState[BTN_HOT_TUB_ON_OFF] = HIGH; }  
  else 
  { InputButtonsCurrentState[BTN_HOT_TUB_ON_OFF] = LOW; }
  
  if (btnJets.onPressAsToggle()) 
  { InputButtonsCurrentState[BTN_JETS_ON_OFF] = HIGH; }
  else 
  { InputButtonsCurrentState[BTN_JETS_ON_OFF] = LOW; }

  if (btnBubbler.onPressAsToggle()) 
  { InputButtonsCurrentState[BTN_BUBBLER_ON_OFF] = HIGH; }  
  else  
  { InputButtonsCurrentState[BTN_BUBBLER_ON_OFF] = LOW; }
}

void setup(){
  pinMode(HOT_TUB_BUTTON_INPUT_PIN,     INPUT);
  pinMode(JETS_BUTTON_INPUT_PIN,        INPUT);
  pinMode(BUBBLER_BUTTON_INPUT_PIN,     INPUT);
}

void loop() {
  ReadInputButtons();
}

Hello,

I am trying to do a similar thing. I have a 2x2 sparkfun rubber buttons. Everything is fine when I use onPressAsToggle() to give it a colour to an RGB LED when I press the button (not the ones in the buttons) and when I press it again to turn of that LED.

The problem is that when I press a different button and any of the others are giving a colour, the colours mix together. I want to switch off any colour when I press a different button.

Is it possible with this library?

Thanks in advance and keep on the good work in this great community that is so helpful
