I’ve already searched through the internet but cannot find satisfactory answer. Is there an easy way to get value of variable passed through an URL? What I mean is I want to start a web server on my Arduino then call the URL like 10.0.0.1/?var1=x&var2=y from my browser and read var1 and var2 to my program. I could also use JSON format but how to send it to my Arduino and then read it? I use Arduino Ethernet Shield W5100. Any ideas?
