Hi, may you please give a suggestion ???!

Hi i'm matmany, and i'm creating a project with arduino and a web page interation
in my web page i'll set any time (year,moth,day,hour,minute) to a blink a led in arduino
when the setted time matches with the present time it will send a signal to arduino
it will work like a alarm.
and i'm not sure about which programing web language should i use (javascprit or php).

i know how to make the basics interation between arduino and a html web page (blink and print)
please any help or tip!!!

I would use a webpage coded in html and php to create an rss file based on the inputs from forms. Then, you need to create a sketch that will fetch the rss file every so often. You'll need to connect to the Internet. An esp8266 module is a cheap way to accomplish that.

thank you!!
