Détécter la présence du shield Adafruit LCD (I2C)

Posted: 14 May 2013 03:16 AM PDT

Bonjour,

J'aimerai utiliser mon shield LCD comme un "programmateur" pour paramétrer certaines valeurs de mon programme, stockées dans l'EPROM.

Pour ce faire, l'Arduino devra détecter au BOOT si le shield est branché, et la deux possibilités :

Bonjour,

Merci pour ta réponse. Le choix du module ethernet est pour la suite du projet ( conversation entre plusieurs arduino, etc...)
J'ai tenté de coder comme suis

I am new to this kind of world so my excused if my question is very simple.

Try to "isolate" the issue. Do split the code into smaller chunks with certain functionality, and try to trigger the issue somehow, or just observe until the issue occurs..

Using MP3 Player Shield with custom pressure sensor

Posted: 14 May 2013 02:14 AM PDT

Hey all,

I'm using pressure sensors to trigger the MP3 Player shield to play certain .mp3 files. When it comes to the arduino code however I'm having trouble getting started on linking these pressure sensors (analog pins) to play mp3 files from the SD ...

Existential Emergency Phone

Existential Emergency Phone how-to by Randy Sarafan:

The Existential Emergency Phone is a multipurpose tool for handling all of life's uncertainties. It can be used for both dialing out and calling in. The way that it works is that when you pick up the handset, the telephone makes a call using a custom cellular module to a list of predefined phone numbers. Whether the phone calls a list of people you know, a list of people you don't know, or randomly dials strangers in your area code, is really up to you. Alternately, the number can be distributed to people with existential emergencies and they can dial in for others to answer. The many manners in which the phone can be used makes it well suited for processing existential emergencies both outgoing and incoming.
