Todayβs tutorial is a bit different: Iβm going to show you how to make your ethernet shield wireless!
You can find many Wi-fi shields for Arduino: starting from the official one, Β up toΒ shieldsΒ based on Microchipβs ICs.]
Sometimes however it could be easier (and maybe cheaper!) to connect an Arduino to the Wi-fi network using your ethernet shield in conjunction with aΒ wireless router.
I found theΒ TL-WR702NΒ nano router by TP-LINK that, with a cost of about 20β¬ on eBay, can work also as a wireless client: in this mode the router acts like a βbridgeβ between the device connected to its ethernet port and a Wi-fi network.
The TL-WR702N router is also very small and you can power it through a micro USB connector:
