Hi everyone,
I would like to a standalone wifi arduino but I have no idea how to do it with the wifi, anyone one has done this before?
WI-FI is something that I will also be looking at in the future as I learn more.
Just had a quick search and this YouTube Video looks really useful with a step by step guide on a small project.
Think I will now search on eBay for the WI-FI module myself now.
Good luck, post back your project as it will make some interesting reading.
Much depends on what you mean by "stand alone"? Do you mean a bare ATmega328P chip with minimal components? Do you mean something battery powered? Do you mean an Arduino not connected to a USB port?
Please be more specific.
I mean as less expensive as possible, so i thought an Atmega with minimal components as base for a usual standalone + wifi component for wifi connection.
Is it possible? I can't find anything in internet.
Just to let you know that I've just purchased a small board for just over £5 delivered.
I don't think that you can get much cheaper than that for a working unit.
Some of the full boards can cost over £100 which is out of my price range.
Search around.
If you just wan't wi-fi connection you shouldn't need to spend a lot.
- wifi component for wifi connection. Is it possible?
If you have to ask then no it is not possible. You will require a PCB which are expensive for one off and the knowledge to layout an RF circuit, which you have not got.
I'm simply using an ethernet-shield connected to a Wifi-repeater for my standalone arduino and have little experience with other options yet..
If you google "Arduino wifi" you'll find several boards/modules you can use.
Arduino Yun, Arduino wifishield, USR-WIFI232, CC3000, cc3100, cc3200, RN-XV module by Roving Networks to name a few.
There probably are more and it is a good idea to check what's on the market/ best for you.
You mention price as important, but I'd also look at things like support, power requirements,
size of board, Antenna-type and reviews by other users.
A new type module, the ESP8266 was introduced on the market very recently by the way and it may... be very interesting. It's available for ~$5 and... is equiped with (programmable) 32-bits microcontroller, which could eliminate the need for an arduino.
Since the module is very new, there unfortunately is no "easy" IDE to program them (yet) and there also is little support (yet). It costs close to nothing though, has a lot of potential and lots... of people are interested.
For a small WiFi device you should skip the Arduino and develop for the ESP8266. It is a WiFi System On Chip processor you can get mounted on a breakout board for $5. It is not as easy to use as the Arduino but it is small, cheap, and WiFi connected.
