Hi.. Is it possible to connect 2 tactile switch on a 1 output in mobiflight?

#

short answer is NO. There is no support for mixed mode arduino pin usage. You either define a pin as input or output... it can't be both.

#

even if technically it would be possible.

#

maybe I don't understand your diagram

#

how do you know which of the four buttons was pressed?

#

all four buttons appear to trigger the same button pin.

#

so to the arduino firmware, you are only pressing one button.

#

there is no button connected to any output pin in this diagram.

#

You said to connect 2 tactile switch on a 1 output in mobiflight

#

that is not the case in this diagram

#

I have 2 led tactile switch ina dualkorry and i decide to connect like this also one of button legs will daisy chain ground...also i want to activate other switch with same output...?

@tulip hatch what is the problem you are trying to solve?

#

I want it to function same when either or both are pressed...

#

that is a solution, what is the problem to solve?

Problem is that my button has 2 tactile switch and when i use it It doesnt activate the function because sometimes the other one that not connected pushing

#

ok, hmm, which button is it?

#

oh wait is that the Korry by Karl?

#

so it is two pushbutons and depending on which edge you push either one or both activate?

#

so you can wire both buttons to the same pin

#

each button has two contacts that connect when pushed, so just wire one to GND and the other to the arduino button input pin

#

grounds together, and button1 pin to arduino button pin, and button 2 pin to the same pin?

#

so either or both connecting makes the button signal

#

or you can just connect them together at the button end

#

so GND-GND--> arduino GND
BTN1-BTN2--> arduino button input pin

Is it true that i add a connection plan for korry?

#

if this is not your design, you really should ask better instructions from the person who made this?

#

but that might work - do you have a multimeter?

#

because I am not sure which one of those 4 legs per button do connect and which direction

#

so with a multimeter you need to identify which pairs of pins connect

#

so find two pins on each switch that connect together when pressed

#

and take two of them to GND

#

and the other two to the arduino pin

#

and that should work

#

#

you just need to make sure the two pins you use per switch actually connect

#

and the switch has 4 pins

#

like this usually

#

so you need to use 1 or 2 and 3 or 4

#

1 and 2 does not work, and 3 + 4 does not work since they are always connected

#

and I think it might be like this, but check with a multimeter beeper
