délai de pression sur bouton poussoir

-

bonjour ,

je suis en plein confection d'une bombe factice airsoft et je cherche comment dire mon arduino : si le

bp est activer pendant 20 sec alors tu lance le compte rebours sinon tu fait rien . je sais c'est

surement très simple pour vous genie de l'électronique mais pour tout les débutant et dont moi c'est une

leçon de

plus apprendre .

je vous en remercie d'avance

 il faut 2 variables

code: [select]
unsigned long tempsdebut;
boolean boutonappuye; // vrai si le bouton est appuyé


initialiser boutonappuye = false ; dans le setup()

dans la loop()

vous regardez l'état du bp

s' il est enfoncé (lire digitalread(bppin) == low ou == high // (suivant si vous utilisez un pull ou pas) et qu'il n'était pas enfoncé juste avant (boutonappuye == false) vous enregistrez millis()  tempsdebut = millis(); et mettez le booléen "bouton enfoncé" à vrai boutonappuye = true;

s'il est relâché alors boutonappuye = false ;

si boutonappuye et si (millis()-tempsdebut >= 20000ul) alors 20 secondes se sont écoulées, mettre l'état actif

hey everyone, i'm trying compile simple code on rpi3 using geany. code written using code::blocks on windows , working without problem. errors i'm getting are: untitled.c:33:5: error: ‘for’ loop initial declarations allowed in c99 or c11 mode , untitled.c:33:5: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 compile code understand code not problem way i'm compiling it. can give me advice? you need add 1 of suggested options compile command configured in geany, in menu.. build -> set build commands add "-std=c99" after "gcc" in compile , build boxes. (i'm looking on mint pc expect version on pi same). petero raspberrypi
