  • digitalRead(. . .)
    This returns HIGH or LOW not 1 or 0
  • Use #define macro to help document your code. Helps others understand too.
    Example
#define CLOSED   LOW
#define OPEN     HIGH
. . .
digitalWrite(fillvalve, LOW); //Initialize valve closed
//Change to:
digitalWrite(fillvalve, CLOSED);
