Ligne 2 :
Ligne 2 : − + − The Trinket has the capability to design an excellent alarm at a price point much lower than other alarm platforms. There are 5 general use pins, three of which may be digital or analog. At a minimum, you would need one sensor (or sensor branch) in, and one annunciation path out. That uses two of our five pins, thus you can have an annunciator that uses up to 4 pins or several sensor branches and more modest annunciator.+ − We will use a generic monitored area in the presented design. A single area alarmed and annunciated either locally or to a remote site. You can use the technique to wire multiple rooms (doors, windows, movement) but there are limitations to the number of sensors if you want to know the exact sensor number. If you only need to know "something" happened in a sensor chain, a nearly unlimited number of sensors may be used.+ + + + + + + + + Ligne 14 :

{{bloc-etroit|text=This tutorial will take sensors, add central monitoring code, and output alarm events to an annunciation system (another computer connected via Bluetooth). Several configurations will be shown to allow you to configure your own alarm system.
{{bloc-etroit|text=Ce tutoriel regroupe quelques senseurs, ajoute un code de surveillance centralise et génère un événement d'alarme vers un système annonciateur/annonceur (un autre ordinateur connecté via Bluetooth). Plusieurs configurations seront présentée afin de vous permettre de configurer votre propre système d'alarme.
Le Trinket peut être utilisé pour concevoir une excellente alarme à un prix nettement inférieur à d'autre plateformes. Il dispose de 5 broche d'utilisation générale, dont 3 peuvent être utilisée comme broche digitale ou analogique.
Au minimum, vous aurez besoin:
* d'une entrée pour le senseur (ou branche/ligne de senseurs),
* et d'une sortie pour l'annonceur/annonciateur.
Cela utilise donc 2 des 5 broches disponibles, il est donc possible d'avoir des annonceurs/annonciateurs pouvant utiliser 4 broches ou plusieurs branches/lignes de senseurs combinés avec un annonceur/annonciateur plus modeste.
Dans la concept ci-dessous, nous allons utiliser un système de surveillance générique. Une alarme pour une zone unique avec un annonceur/annonciateur vers un site local ou distant. Vous pouvez utiliser cette technique pour câbler l'alarme dans plusieurs pièces (portes, fenêtre, mouvement) cependant...
* SI vous voulez savoir quel senseur est activé ALORS il existe une limite maximale au nombre de senseur que vous pourrez mettre en oeuvre.
* SI vous voulez seulement savoir que "quelque-chose" est arrivé sur une ligne/branche de senseur ALORS vous pouvez utiliser une quantité quasi illimitée de senseurs.
A typical scenario is monitoring a place like a room or a garage. The garage has a main garage door, a side door and the space within the room (a regular room would substitute a window for the garage door). To cover the area well, a magnetic contact will be placed on each of the areas that can open/close plus a volumetric (area) sensor in case one of the other sensors fails or someone breaks in without tripping a magnetic contact. You can always go to extremes covering an area but it only costs resources (money and processor pins) without providing much more security. }}

This design will use one analog sensor branch per the design diagram. The Infrared sensor and the magnetic contacts will be wired together into an analog ladder per alarm basics. These will be transmitted via Bluetooth to a monitor room inside the house. A good design has the monitor away from the area to not allow the intruder to disable the alarm easily.

This leaves many pins for additional sensors or other annunciation.
