Turn off buzzer via web

Hi guys, help me…

I have RFID RC522 project using web application with buzzer alarm on Arduino

The case if the RFID tag is detected unregistered 5 times on the RFID reader then buzzer alarm active 1 minute

Can I make a notification on the web if buzzer active? And then can I turn off buzzer directly via web, without switch or push button components?

Thank you very much :slight_smile: sorry if my english bad

Can I make a notification on the web if buzzer active?

You can make the Arduino, with ethernet shield, act as a server, and serve up a page that contains static content that tells whether, or not, the buzzer is squawking its fool head off.

You can make the server respond to GET requests. A GET request could cause the buzzer to be shut off.

But, the status of the buzzer can NOT be pushed to client(s). The client(s) MUST ask. You can include meta tags that define how often the client(s) re-request the status of the buzzer.
