Analog to digital how ?



  • Hi there,

    I would like to know what and where i have to look for.

    I reading with my nano 328 port A0, A1, A2 voltage from "3" motion senors
    and get a specific value >700
    if one of those ports gets above this 700
    I would like to send this true mysensors as an normal motion sensor normal true trigger
    but im not using any interrupt
    How do i send this ?

    if (analogRead(A0) >=700)
    {
    send(msgmotion0.set(tripped0?"1":"0"));

    and for the others.
    send(msgmotion0.set(tripped0?"1":"0"));
    send(msgmotion1.set(tripped1?"1":"0"));
    send(msgmotion3.set(tripped3?"1":"0"));

    @Rene046 how about something like this?

    void Pirlezen() {
      bool pir = analogRead(A0)>=700;
      send(msgmotion0.set(pir));
    }}

  • All working fine sometimes the pir reaction could be a bid faster, and sometimes i get a false reading think i'll have to put the pir signal lines to the ground with an resistor.

    Any advice is welcome, to make thing faster, and less complex.
    else use this with fun......
