Arduino WiFi Dongle Connection I want to use a my existing WiFI USB Dongle with Arduino Uno. I know that there is no USB port in Arduino Uno as such so I opened the USB Dongle and Soldered it so that I can plug the wire to Arduino. Below is the picture of Dongle - 



Now the problem is, I am not able to find any way to use this with Arduino. I can see there are some standard WiFi modules like WiFi Shield and ESP Module available which are mostly used. But is it necessary to use those modules only ? Can we use this USB module and if yes then how ?

The details information about this WiFI dongle is available at below path -

No, you will not be able to use this dongle. This device needs to be plugged into a USB Host device, which an Uno is not capable of doing for several reasons, one of which is that this dongle would require some driver on the host device, and the only drivers made for it are likely made only for Windows/Mac/Linux type operating systems.

Most of the WiFi shields communicate with Arduino over a non-USB protocol like SPI or I2C, while it looks like this dongle is a purpose-built chip that communicates with a host over USB only, not I2C or SPI.

It's likely you can find an ESP8266 device for a lower cost than this dongle would cost, however. The ESP8266 device would communicate with an Arduino via UART (serial port).
