I am new to arduino..I have connected rfid reader(rfc522) and it functioning properly.Now I need to store the data received from the rfid to a online database. For that I need to connect arduino to internet and I am trying to do that with wifi module. But not able to find any good resource .Can you help me out here..
If you are looking for a way to transfer your RFID data to your online database, I suggest using an ESP8266 Module. This is a low budget wifi module which can be simple connected to an Arduinoboard.
You can also choose for the Arduino Wemos D1 R2, which is an Arduinoboard that is compatible with the Arduino Uno but contains a Wifimodule.
Hope this will solve your problem.
