I have a generic question about which approach to pursue. My goal is to have a webpage (hosted on a local apache webserver, not on the arduino) that allows me to input a value in a box that in turn changes an Arduino variable to be utilized by a particular function. My question is: is this best done by having the Arduino ethernet client read this data directly or by having the webpage write the data to an SD card and have the Arduino parse that file?
I've searched the forum and found examples for both approaches but unsure which approach is fundamentally more sound for my use case. Think of this webpage as being used for initial setup values, as I don't expect them to be changed frequently. I do expect to be able to figure out the specifics of either approach but need assistance, from someone smarter than me, in determining which path to take and why.
Thanks in advance!
