thanks for your explanation.
one more question:

[code]

void setup(void){Serial.begin(9600);}

char *p_string(void){
char string[20];
uint8_t cnt=0;
char inChar;

if(Serial.available()){
while(inChar!='\r'){
if(Serial.available()){
...

If you using those digikey converter then you no need those resistors, connect to ground directly.
those resistors needed when you used LM317.

Ciao,
Il PWM sulle ventole a mio avviso non ti serve, se le plafo sono troppo calde le accendi, fino a quando è necessario e amen, i sensori di temp, grazie al one wire, non sono un problema, ne metti in cascata quanti ne vuoi, mentre il conteggio dell...

grazie per la risposta:)
c'è una cosa che però non riesco a fare..cosa scrivere nello sketch per dire ad Arduino "a quest'ora fai questo.ecc." ..
con la libreria ho settato l'ora, ma non so come fare poi il riferimento ad un orario preciso nel loop!:/

Utilização de varios sensores de Monoxido Carbono no arduino

Bons dias

Tenho um projecto em mente que seria ligar cerca de 5 sensores de Monóxido de Carbono a um arduino de forma a criar um sistema de detecção de CO para um sistema de extracção.

Alguém sebe se é possível e se alguém já trabalhou com esse tipo de...

Balancing Robot using a Raspberry Pi

Balancing Robot using a Raspberry Pi:

When I saw my first two wheel balancing robot I was very fascinated. And after receiving my Raspberry Pi, I decided to build one myself.
PiBBOT (Pi Balancing roBOT) is my first successful balancing robot. And it has room for improvement and extra functionality.

When I need longer range, I use an ethernet board and feed it into one of the long range, weatherproof WiFi modules from Ubiquiti (http://www.ubnt.com/). They are well built and have great software but are not that expensive. (see http://www.wifi-stock...

1- Open X-CTU and go to the Modem Configuration tab.
2- In Modem: select XB24-DM or XBP24-DM depending of using XBee or XBee pro.
3- Configure parameters as you want.
4- Press Write to flash module

You can do the reserve process to go back to 802.15.4,...

Hi,

die Doku http://arduino.cc/en/Reference/ClientRead verrät dir was der client.read() Aufruf macht.
Kurz gesagt arbeitet dein "copy/paste" Programm so, dass ein TCP-Stream byte für byte ausgewertet wird.
