1) Is there an Arduino design with one processor and a WIFI device on a single board?
2) Does someone have recent experience with a WIFI shield - one that they can recommend and why?
3) Comments on other WIFI shields - pros and cons in your experience; what definitely not to get?
2) Does someone have recent experience with a WIFI shield - one that they can recommend and why?No, but there are not that many choices any more. The market just isn't big enough.
Are you saying that many are the same product by different manufacturers?
So you would caution at least on the support side, and perhaps om the quality side?
And why is wifi not so popular?
Quote1) Is there an Arduino design with one processor and a WIFI device on a single board?Yes, there is one, although not in the common form factor:http://www.seeedstudio.com/wiki/Wifi_BeeIt's an ATmega328p with the Arduino bootloader and a wireless module like the one on the WiShield together on a small PCB compatible with the common XBee sockets. Depending on the planned usage this might be enough by itself or (as is my usage) share the work between the main Arduino (controlling the IO) and the Arduino on the Bee (handling all the network stuff). It's your choice if they communicate over the serial interface (UART) or the I2C bus.
I don't know less about the XBEE series than I do about the Arduinos
and I don't really want to start with a compatible device this early in the game.
QuoteI don't know less about the XBEE series than I do about the ArduinosSo, you know more about XBees than Arduinos?Quoteand I don't really want to start with a compatible device this early in the game.So, you'd rather work with an incompatible device? Just so I have the picture clear.
I am just starting on the Arduino, and would not like to mix in items that aren't really Arduino in design
QuoteI am just starting on the Arduino, and would not like to mix in items that aren't really Arduino in designThat's very unfortunate because from Arduino there is NO WiFi hardware at all, so you have to forget about WLAN and Arduino if you're stuck with the original Arduino only.The WiFi Bee is just another form factor, it's not a ZigBee as you might have thought from it's name. Arduinos (also the original ones) come in a lot of form factors, from the Mini and Nano over the UNO to the Mega2560 you have a lot of sizes and shapes. Regarding the size: a Lilypad is neither really bigger than the Bee nor better to connect.
I guess you are telling me that these are all NOT Arduino designs. Is that correct?
And, yes, I thought the XBee is for the Zigbee designs. But will it do WIFI so I can talk to it via my laptop or router. And, if so, can I run the IDE to communicate via WIFI - that's the bigger question?
The other real concern is in case of trouble when one manufacturuer points to the other's product as having the problem (although that may well happen anyway, I guess).
