Does it make any difference, in terms of used amount of RAM, speed and stability, using the Websockets instead of HTTP?

Hi Rockwallaby,

It would be great if you could also post some parts of your PHP listener.

Thanks

Just a quick update:
Many thanks for your examples. I'm using them to debug more and trying new things.
My general impression for now is that the shields functions, but freezes often when reading data (a text file) from the server (client.read()).
I'll post more later.. bye!

Are you sure the webserver is always available when Arduino tries to read that file? Somebody here on the forum wrote that the method "connect" of the "EthernetClient" class contains a loop of 10 seconds to retry connecting. If the webserver doesn't respond, Arduino hangs. That guy solved the issue by making Arduino act like a server. It waits for a command from the webserver and only then it connects to the webserver (this way Arduino knows the webserver is online).

Ok grazie, a dire il vero avevo anche pensato di suddividere i compiti a due Arduino differenti, e collegarli tra loro via seriale, ma i costi sarebbero aumentati. Proverò questa strada. Grazie ancora

Ciao Simone,

Sei riuscito alla fine a risolvere il problema?

Would it be possible to have an example about how to manage some of the PIN's status (something like ON/OFF).

I have an 8-channel relay board and I have been planning to write an example how it could be used as a timer controlled by a web gui. I'll send you a pm once I get it done and uploaded to github.

Thanks a lot !!!

If I wanted to use this as a human detection sensor, what would be the maximum range that I could expect to detect a human?

From the photo posted on their website it seems to be 10 cm.

Hi llukkari!

It seems very interresting. As soon as I'll have some spare time I'd like to try your code. Would it be possible to have an example about how to manage some of the PIN's status (something like ON/OFF).

Also, I'd want to ask you what do you think about using a database in the middle and just querying the database to show the status of the Arduino PIN's (the values and the status of the PIN's would be pushed into the database using 2 services: one on the arduino and one listener on the webserver that registers all into the DB at a predefined time range).

The use of the database will avoid "overloading" with requests the Arduino board

devo ancora implementare la restituzione della pagina web da SDcard, per ora l'ho provata residente in locale, per provarla con lo smartphone ho abilitato IIS. Nel frattempo vi allego il file html e lo sketch.

Sono riuscito a caricare il codice su un'Arduino Uno e IDE v1.0. Ho notato che il cambio dello stato dei pin digitali non funziona sempre oppure è molto lento. A che cosa possa essere dovuto?

Would it be possible to make the 2 buttons show the status of the LED? (for example, if the LED is ON, the ON button should be dimmed)

Siccome sono alle prime armi, ti sarei grato se potessi postare le modifiche da aggiungere nel codice di Illuca.

Grazie mille

Ho da poco iniziato anch'io a smanettare con l'ethernet shield. Avete, per caso, risolto il problema dello slider?

Grazie

Let's imagine to have a board could be easily connected to pushbuttons and/or switches like the one provided by Living Series or similar. A board with ATMEGA328, power supply and the RS485 bus logic onboard, with LEDs (RGB?) placed in the proper position in order to be fitted in the Living pushbuttons hole for status indication... Something like a piggy back for three standard switches...

Great idea Marco. I'm following your thread since the beginning. Unfortunately I have no such experience in this field in order to be able to contribute.

Magari puoi utilizzare la libreria IR per controllare il condizionatore attraverso un LED IR e un sensore di temperatura che legga la temperatura dell'ambiente.

Io ho utilizzato con successo le informazioni trovate qui:

Sono riuscito a registrare i codici per 2 telecomandi e poi a controllare la TV (Sony) e il decoder DVB-T.

Hi,

I've built myself a copy of the ChronoDot RTC device (DS3231 based) and attached it to the Arduino.
My arduino is attached through the USB port to an OpenWRT embedded device that has no RTC.

I'd like the OpenWRT device to sync the time and date, when booting (using a script executed at the boot time, as a backup in case the internet connection is not available), from the RTC attached to the Arduino.

I'd apreciate any idea about how to do this
