What is it that doesn't work?
Can you send messages from an Arduino with the Tx module to the Arduino with the RX module?

The codes are a function of how you have set the dip-switches in the contacts.
The easist way to work out which codes to use is to use the receiver program mentioned above.

One of the other readers of this page got it to work a couple of months ago. He sent me a class with
codes for the Harald Nyborg contact, but I cannot find his source code.

Thanks for your help. I'll get a couple, and give it a try.

3  Using Arduino / Networking, Protocols, and Devices / Jeelab Dimmer plug on: October 25, 2011, 02:02:18 pm

 On the Jeelab web page it says that their dimmer plug with the PCA9635 IC works at 3.3V.
 What confuse me a bit is the PCA9635 data sheets says the chip works in the range from 2.3V-5.5V.
 Based on the data sheet I would expect to be able to connect the dimmer plug directly to the 5V Arduino I2C.

 Does anyone have experience with connecting the Jeelab dimmer plug directly to the Arduino?

Per me Arduino non è per gli gente che non vuole imparare nulla.
Arduino è un micro computer facile, che fa possibile imparare programmazioni e elettronica.
Gli studenti o altri gente che vogliono provare fare un poco con un micro computer hanno bisogno un sistema facile e economica. E poi quando hanno fatto qualcosa, alcuni di loro si informano su programmazioni e elettronica.
So alcune professori nella un università in Danimarca chi usare Arduino per svegliare la curiosità nella studenti, e poi insegna come programmazioni un "vero" micro computer.

Per me Arduino è un sistema per svegliare la curiosità, e anche un sistema economica per fare progetti nella casa.


PS! Scusi per il mio italiano. Io sono un danese, ma voglio imparare italiano

 Jeg kikkede lige hurtigt på, men valgte hurtigt at gå videre da jeg ikke
kan finde adresse eller cvr nummber på firmaet på hjemmesiden.
 Jeg har ingen dårlige erfaringer med dem, men det undrer mig meget at man ikke kan se information om firmaet på dens hjemmeside.

6  Using Arduino / Networking, Protocols, and Devices / Re: using dallas 1 wire on which pin? on: June 13, 2011, 01:30:58 am

 You can use any digital pin. The pin number used for talking to the 1-wire devices are decided by line 4 in the tutorial (OneWire ds(10);  // on pin 10) .  To use another pin just type a different number than 10, i.e. OneWire ds(4);

 We have used 1-wire sensors for a floorheating system in my brothers house, and it works really well.

7  Using Arduino / Networking, Protocols, and Devices / Re: TCP DIALOG between ARDUINO and VB.NET program on: May 07, 2011, 03:20:26 pm
I have setup the arduino as a tcp server in my home heating setup.
My argument was that the PC wouldn't always be on, so there was no need for the
Arduino to try to connect to it.

Hope this helps - it seems like you have posted the same question in the Italian section

 I have thought about automating my window, so I would like to know which actuator you use to turn the window blinds?
9  International / Scandinavia / RemoteSwitch library virker fint med Sartano fra Harald Nyborg on: April 17, 2011, 02:59:58 am

 I et stykke tid har jeg overvejet om man mon kunne styre Sartano stikkontakter fra en Arduino. Igår købte jeg så 3 trådløse stikkontakter af mærket Sartano, og det er super nemt at få det til at virke med de 434MHz sender/modtagere man kan få til Arduino.

 Download RemoteSwitch library fra Arduino's playground. Start med at dekode fjernbetjeningen ved at bruge show_received_code programmet.  Programmet giver en code og en duration. Med den valgte indstilling af dip-switches fik jeg code 172712 og duration 320 for at tænde kontakt D.

 Herefter åbnes light_show sketchen. I stedet for de koder der er for at tænde slukke i eksemplet, bruger jeg
  unsigned long code;
  unsigned long period = 320L;
  code = 172712L; //D on
  code |= (unsigned long)period << 23;
  code |= 3L << 20;

 Nu skal jeg så bare have fundet ud af hvad jeg vil bruge min trådløse kontakter til.

Thanks for your replies. I hope to get to work on the 2408 this week.
Looking at the datasheet and the 1820 code, I have a feeling that it should be fairly straight forward.

 Do you know if there is Arduino code available to interface to the DS2408?

 It would be fairly easy to interface to it using the 1-wire library, but if the work has been done already it would make more sense to spend my time on interface that aren't already available.
