  FACTS P1AM Example Series #2 - Web Server Analog Input

  This example uses the P1AM-ETH shield to create a webserver that displays the input values of a P1-04ADL02 to a webpage.
  You can visit this webpage by entering it's IP address in a browser. the default address is 192.168.1.177.
  This page will display the readings of all 4 channels in volts and in counts.

  You can find information on the P1-04ADL-2 and other modules here: https://facts-engineering.github.io/modules/P1-04ADL-2/P1-04ADL-2.html

  The analog input module we used is the P1-04ADL-2, though you can easily use any analog or discrete module as long as you tweak
  the conversions for your range and resolution.
  If you use another input module you may find our configuration tool handy for setting ranges: https://facts-engineering.github.io/config.html

  This example can easily be changed to display multiple modules and their data. This is great for any sort of remote monitoring you might want.
  If you're comfortable with basic web development you can spruce up the website and add plenty of features of your own design.
