Hi Nick,
No, it wont on its own. In my original post I said..

"I include the logging code here so perhaps someone may spot something I'm doing wrong. It is only a section of the complete code".

I was hoping that someone may spot an obvious error in the...

da das KFZ Bordnetz Störungen verursacht würde ich noch eine Schutzschaltung für den Analog eingang empfehlen

Mal abgesehen davon, dass Schutzschaltungen nie schaden,
verstehe ich das so, dass die Schaltung von den 5V des Arduino gespe...

Thanks a lot!! It was in a big help

Alimentare arduino con batteria 12 Volt

Posted: 25 Mar 2013 02:48 AM PDT

Ciao a tutti,
pensavo di alimentare arduino ( e relative periferiche, tipo sensori pir) con una batteria al piombo da 12 volt e relativo trasformatore come consigliato da uwefed.
La mia domanda era: in questo modo tutto il sistema è protetto da eventua...

Semplice domotica con Arduino Ethernet

Posted: 25 Mar 2013 02:48 AM PDT

Giorno a tutti, la mia domanda è del tutto teorica, qual'è il miglior metodo di comunicazione tra un server e l'arduino con shield ethernet.
Il mio dubbio è tra la classica richiesta http o una connessione socket (sono le uniche opzioni che mi vengono ...

Template per AVRStudio 6 e define ARDUINO=xxx

Mi sto facendo un template per AVR Studio 6 per poter programmare l'Arduino con la suite Atmel ma mi sogne un dubbio. Sono partiti da un template che ho trovato sul forum (non mi ricordo il link) ma fra le opzioni del compilatore c'è ARDUINO=100. Adess...

9600 baud is quite slow

I thought of the same case but even I then I don't think that I will get my Serial.reads read correctly as it will still keep on creating interrupts

Re: Generatore PWM verso regolatore Jeti

fatto un pò di prove.
il regolatore riscalda tantissimo anche se lo tengo attivo per 2 minuti al massimo.
con il jeti box ho impostato default setting per evitare impostazioni sbagliate.

avete qualche idea sul motivo per cui ...

This is the combined code that doesn't work.

Re: Quale memoria?

Posted: 25 Mar 2013 02:13 AM PDT

C'è la 23K256 disponibile, è sempre in formato DIP8 e seriale SPI (max 20 MHz), ha un taglio di soli 32 kB (256 Kbit) ma se devi registrare 12 kB di dati ti basta.

Potrebbe fare al caso tuo?

Re: UART operations with Interrupt0 on ATmega328

Posted: 25 Mar 2013 02:07 AM PDT

Code:

volatile int AC_LOAD = 3; // Output to Opto Triac pin

Why "volatile"? Why not "const"? (and, as a side-order, why not "byte"?)

Re: Modify code for laser harp

I am not a fortune teller but I foresee the use of arrays in your near future and the removal of delay() from your code to keep it responsive.

Re: digital clock with arduino

Posted: 25 Mar 2013 02:05 AM PDT

Code:

seconds();
minutes();
hours();

These function names do not imply, in any sense, what the functions actually do. They need to be renamed.

Code:

Re: IR range/proximity detector not working as expected

In which case why the mistery? If the torch ( that is what we say for flash light ) is just in the room the reflected light will not be enough to trigger the sensor, but when turned at the sensor it is intens enough to show something.

Qualcuno saprebbe dirmi dove trovare i 23LC1024?

Su RS non arrivano prima di metà a prile, su Farnell bisogna spendere almeno 50 euro+ iva. Ho provato a vedere se avevano l'Arduino DUE ma non l'hanno, per cui non saprei proprio come raggiungere quella ...

Are we already ready to transition from CFL to LED lightbulbs?

Posted: 25 Mar 2013 02:00 AM PDT

via nytimes:

LED bulbs last decades, save electricity, don't shatter, don't burn you, save hundreds of dollars, and now offer plummeting prices and blossoming features. What's not to like? You'd have to be a pretty dim bulb not to realize that LED light is the future…

LEDs last about 25 times as long as incandescents and three times as long as CFLs; we're talking maybe 25,000 hours of light. Install one today, and you may not own your house, or even live, long enough to see it burn out. (Actually, LED bulbs generally don't burn out at all; they just get dimmer.)

Well it is backwards. That is control 3 is normally the most significant bit not the least.

It makes a nice neat package, and is designed that you can put them together horizontally or vertically.

You are trying to use some variable which is of some class String, as an argument
to a function which is expecting an argument which is of type pointer to char.
