Again there are many ways to alert you if the alarm has tripped. Some of my favorite ways:

# '''Speaker''': the simplest method is to use a loud noise. The piezo speaker does this well - you can output several tones or just an ear piercing tone. You can use an audio amplifier to make a louder sound. You will need to match the wattage of your speaker to that of the amplifier. Between the Trinket and amplifier ensure you do not input too much power or voltage.

Between the Trinket and amplifier ensure you do not input too much power or voltage.

# '''Display''': if you leave Pins #0 and #2 (the I2C pins) free, a character display with backpack could display the status. You may also use an LED as a simple indicator. The Trinket Pin 1 built-in LED is perfect for this although Neopixels or other LEDs could also be used.

# '''Communication''': My favorite - leverage the power of your home network to get a signal out. Trinket does not have enough memory to use a Wifi shield directly. But a serial link like new {{pl|396|Bluefruit-EZ -Link}} or an {{pl|77|FTDI Friend}} can be sent to another computer to get the word out - leverage your cloud to spread the alarm message.

# '''Communication''': Mon préféré - profiter de la puissance du réseau de votre maison pour envoyer un signal d'alarme à l'extérieur. Le Trinket ne dispose pas d'assez de mémoire pour contrôler directement un shield WiFi. Mais un Trinket peut d'appuyer sur une liaison série vers un système plus puissant avec un {{pl|396|Bluefruit-EZ -Link}} ou un {{pl|77|FTDI Friend}} de quoi envoyer un signal vers un ordinateur (ou Raspberry Pi) - Avec un tel système, il est même possible d'envoyer des messages alertes directement sur le cloud (eg: sur Twitter).

ou une '''Combinaison''': If the infrared sensor and all the magnetic switches are on a combined branch on an analog input, then multiple annunciation methods could be available.
