Vacuum pump monitor amps and temperature

C/C++
/*
  Web Server
 A simple web server that shows the value of a0,a1,a2 as three phase power in amps and oil temp using a Dallas 18b20.
 using an Arduino Wiznet Ethernet shield.
 Circuit:
 * Ethernet shield attached to pins 10, 11, 12, 13
 * Analog inputs attached to pins A0 through A2 and digital pin2 for the dallas temp sensor
