choix composants infrarouge

-

bonjour

je souhaite faire des essais de transmission/réception infrarouge et devant la quantité de composants disponibles je suis perdu.

le projet est un système de chronométrage de modèles réduits (donc en extérieur) piloté bien sur avec arduino. la distance de détection sera de 4m maxi.

pour l'émission, je pense opter pour une led 100ma et un angle le plus réduit possible sfh4554.

pour le capteur, tsop 34838 ou tsop 4838 (d'ailleurs, quelle est la différence entre les 2 ? j'ai parcouru les datasheet mais mon niveau ne m'a pas permis de faire une distinction.

pouvez-vous m'aider à faire le choix des composants ?

merci d'avance.

philippe

salut les gars

personne pour me donner un petit coup de main ?  :-[

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
