    Hello Power Users,

    i also have a problem with MMM-Buttons, that Buttonpress is only sometimes recognized if i press twice or triple.

    Intension:
    I want to change MMM-Pages with to buttons, to move left/right through my pages.
    MMM-Remote-Control is set up and works.
    Moving through pages work bei MMM-Remote-Control Links and sendnotification.

    My setup:
    Raspberry 1 B+
    2 Buttons (circuit closed when pressed)
    connected between 1: GND an BCM26; 2: GND and BMC20
    I tested the buttons with a python script an they are recognized

    I searched this forum and still have some questions.

    1. Do Buttons on GND work or do i have to put them on +3,3V with a resistor instead?
    2. how do i use activeLow in MMM-Buttons Configuration? … activeLow: true ?

    Looking forward getting some tips.

    Regards AxLed

      Maybe play around with the min and max Presstime.

      Wondering that this works with the module… when u press the Button the gpio would be set to low which is equal to 0.

      2. how do i use activeLow in MMM-Buttons Configuration? … activeLow: true ?

      Afaik this isn’t possible through the module. Maybe u find a solution in the web, fo how changing the input state detection.

      And yes, u should use resistors for giving the GPIO a defined state when not pressing. When u don’t want to connect them physically (but i recommend) u could use the internal resistors (check below on this site http://wiringpi.com/the-gpio-utility/)

      So normal way (or the way i used) is to connect the button like this:

        Thanks for the tips, you made my day, it works now.
        What i did: Changed the wiring from negativ (GND) to 3.3V (with resistor) as shown on picture of cruunnerr wiring diagram.

        No i try to get a rotary switch and got it working, as i need some WAF (Woman acceptance faktor) for my mirror.

        Regards

            Your wiring diagram is fantastic. Is that a program?
