/* MEM -- Modern Energy Meter
  The circuit:
   LCD RS pin to digital pin 12
   LCD Enable pin to digital pin 11
   LCD D4 pin to digital pin 5
   LCD D5 pin to digital pin 4
   LCD D6 pin to digital pin 3
   LCD D7 pin to digital pin 2
   LCD R/W pin to ground
   10K resistor:
   ends to +5V and ground
   wiper to LCD VO pin (pin 3)
