The weekly – SHOW AND TELL is on the Adafruit Industries Google+ page! at 9:30pm ET We will be asking all the folks in the +Limor Fried (ladyada) show-and-tell circle to re-add themselves to the +Adafruit show-and-tell circle shortly. We're moving the show-and-tell to the +Adafruit page so more of our staff can run the show-and-tells. For example, we'll have a wearable electronics / FLORA themed one with Becky and a 3D printing themed one with Matt.
Please post a comment on the Adafruit page to be added! Make sure you add Adafruit to your circles first!

ASK AN ENGINEER 10PM ET – 12/8/12!
What is "Ask an engineer"? From the electronics enthusiast to the professional community – "Ask an Engineer" has a little bit of everything for everyone. If you're a beginner, or a seasoned engineer – stop in and see what we're up to! We have demos of projects and products we're working on, we answer your engineering and electronics questions and we have a trivia question + give away each week. Mosfet the cat stops by too. Previous chats can be viewed at http://www.adafruit.com/ask
Chat details!
And don't forget, 30 minutes before the show we're doing our weekly show-and-tell. If you are on Google+ and want to join, just add/follow +Adafruit's page and post a comment so you can be added to the show and tell circle. At 9:30pm ET you will see a link to the hang out. Just keep your mics muted until we call on you and have your project ready.
For those who just want to watch, you'll be able to watch it live on Ustream here and we usually have a recorded version posted later.

ok cool i think i made it work smiley

const uint8_t polySides = 4; // 4 sides in your polygon

//                          A,   B,   C,   D
float polyX[polySides] = { 3.0, 7.0, 7.0, 2.0 }; // X
float polyY[polySides] = { 4.0, 4.0, 2.0, 2.0 }; // Y

E' molto strano, non ti pongo la fatidica domanda, anche se prima o poi ci arriveremo smiley-sweat, a questo punto prova con un C molto grande, sull'ordine del µF

Are you using an actual Arduino, or a home-made system based on an Armel processor?

If it is a home-made system, you can probably get it working by changing the fuses that control the clock startup time and the brown-out detection.

If it is an Arduino ...

Certainly it has been done... in your mind... flesh it out and make it real, Then make it Great.. That's what a good design engineer does.

I made this simple, working example:

In this example, the polygon looks like:

bonjour merci pour la doc

alors déjà sur la doc je vois qu'il y a le LM2917 et le LM2907 j'ai donc chercher est apparemment le 2917 a une diode zener incorporer alors que le 2907 n'en a pas lequel choisir ?

forse capisco male, se vuoi portarti i fili sulla breadboard NON puoi cortocircuitare quello attuale, altrimenti anche sulla bread avrai un corto. Il corto fallo per provare SENZA C, poi quello lo devi proprio dissaldare ed allora sì che puoi pr...

Wartest Du dann irgendwo auch die Antwort des Servers ab, der die Daten bekommt?
Wertest Du die Serverantwort aus?

Und was mir auffällt: client.stop(); wird nur im Fehlerfall ausgeführt, wenn kein connect zum Server zustande kommt. Brauchst Du ...

Hi, I am planning on making a display with a few 8x8 (or any other size, doesnt really matter) led matrixes. Are there any tricks to use less pins? Does anyone know of a good tutorial on how to work with these displays? I need to use the least amount o...

Sorry, here is some of the code I am currently using.

[code]
#include "DHT.h"

#define DHTTYPE DHT11

DHT dht(DHTPIN, DHTTYPE);

double dewPoint(double celsius, double humidity) {

But if I have continuing problems, I'll start another thread, rather than hijack this one.

Too late, that horse is dead.

It might work, it depends on how inductive the water pump is. If it doesn't, try connecting a 100W incandescent light bulb in parallel with the water pump and see if that improves things.

Con el módulo que tienes, puede mandar datos perfectamente al telefono para que este lo interprete.
La diferencia entre el modulo máster y el slave es que el master puede iniciar la conexión el solo y conectarse con otro módulo bluetooth una vez que es...
