I'm loving the new neon colors available for summer at Nervous System, especially the rings and bracelets made from generative algorithms.

Re: gps proximity library

Posted: 26 Jun 2013 02:38 AM PDT

yes for simple calculation distance on point,
but it do not undestand the error tollerance of gps,
I read that there are libraries that handle the error by a tracking points and averaging the error.
In my case I would like to implement a track gps wa...

Re: Mega Serial delay

Posted: 26 Jun 2013 02:38 AM PDT

I meant delay(100000) run in 2 secs and delay(2000) are like 1ms.

if(0 < Serial2.available())
{
tem = Serial2.read();
bufferWrite[buffW] = (char)tem;
Serial.print(bufferWrite[buffW]);

Re: How much current flows through a MOSFET when off?

Posted: 26 Jun 2013 02:34 AM PDT

10uA is far less than the self-discharge rate of most batteries - you can ignore FET leakage
at room temperature.

In the diagram the gate current limiting resistor is shown as 10 ohms - no use for the Arduino,
150 ohms would be a more suitable value (k...

And mySerial.available() is always returning non-zero i.e. it's always true.
Only the gps.encode() is always returning false.

Have you printed the data received from the GPS? Does it make sense? Care to share it?

If the GPS is not a 4800...

What am I doing wrong?

The only thing obvious is not posting in the forum dedicated to the DUE.

Re: connect heater ac 220v 1200W to arduino

Posted: 26 Jun 2013 02:03 AM PDT

If you intend to Regulate the mains grid 220v AC to a Lower voltage, it will require huge costs..

The best approach is a temperature control from ebay wich costs $11 w. free shipping

However, if you love the pleasure of creation , then you will ...

Re: ATTiny84 Falling edge interrupt

Posted: 26 Jun 2013 02:02 AM PDT

Thanks again.

I scanned through the .h file but not the .c file. Next time, will do :-)

I am still having problems with SPI, but I will be putting those on another thread.

Thanks.

Regards,
Abe

Merci @68tjs,

J'utilise Windows 7.
Je viens de faire le test sur les broches avec mon multimètre (positionné en ohmètre) et elles sont au même potentiel.
Il faut que je google un peu pour voir comment programmer en SPI à l'aide d'une autre carte ARDUINO.

Testing a Bluetooth Phone Glove #WearableWednesday

Posted: 26 Jun 2013 02:00 AM PDT

Hands-tied kit: Designer tests bluetooth glove phone on BBC:

Increasingly manufacturers and developers are experimenting with wearable technology.

Recent innovations include clothes that display twitter updates, mobile phone headsets, Google glasses, mobile phones that work in conjunction with wristwatches, and bracelets that track your fitness regime.

As an experiment in wearable tech, and to highlight the possibilities of recycling old mobile phones in an imaginative way, designer Sean Miles of Designworks was approached by O2 Recycling to experiment at will.

His latest prototype is customised, bluetooth-enabled gloves, that work in conjunction with a mobile phone – you speak into the pinkie, and listen through the thumb.

At his company's design studio in Windsor, he gave the BBC's Dougal Shaw an exclusive gloves-on demonstration.

Every Wednesday is Wearable Wednesday here at Adafruit! We're bringing you the blinkiest, most fashionable, innovative, and useful wearables from around the web and in our own original projects featuring our wearable Arduino-compatible platform, FLORA. Be sure to post up your wearables projects in the forums or send us a link and you might be featured here on Wearable Wednesday!

Re: Balise Émettrice / Réceptrice IR Pololu

Posted: 26 Jun 2013 01:34 AM PDT

La balise a quatre sorties numériques qui indiquent lequel des quatre côtés détecte plus fortement l'autre balise.

Avec ça tu as une direction de poursuite, il ne reste plus qu'à faire tourner une roue plus vite que l'autre du bon côté et s'orienter.

Thank you for the information and your time.

For sure when I supply with less voltage it stalls.
My initial intention was to read a NTC temperature and set a gradual increase in the pwm of the fan (from arduino) parallel to the temperature increase,(...
