A cheap WiFi interface for Arduino

Alessandro PaganelliDecember 27th, 2012

In this tutorial, Luca shows how to add WiFi connectivity to your Arduino boards without using a WiFi shield. Instead, he has combined a standard Ethernet shield with a commercial (and quite cheap) WiFi router:

I found the TL-WR702N nano router by TP-LINK that, with a cost of about 20€ on eBay, can work also as a wireless client: in this mode the router acts like a “bridge” between the device connected to its ethernet port and a Wi-fi network.

After a simple setup, where Luca configured the router as a WiFi client, the Arduino board has become accessible from the wireless network. Enjoy! :)

    Hello Luca,I’m interested in your Wifi Arduino board,May I know how far its signal can cover?

    Thank you

    Thanks for the tip. I purchased one of these and it works great – as well as Arduino it works on my RasPi. Excellent.

    This looks a bit like the Raspberry Pi.

    Love the idea about the WIFI part. I will buy one off amazon as they are cheap atm

    Thanks
