Good evening,
I have an arduino with 4 or 5 sensors and a rfid module. When I approach the card to the reader this should be able to operate the sensors.
What I would like to do, however, and do not put the codes of RFID cards that can operate the sensors in the source code of arduino, but I want the Arduino communicate (possible via LAN) to a PC or a raspberry / beaglebone / udoo that is connected to internet and make the request and to a cloud server if the card is enabled or not
Is it possible to do such a thing?
I can have multiple arduino.
