ed001987:

void turn (boolean dir)

{
 ...
 digitalWrite(TURNDIR, !dir); // correction
 Serial.print("!dir = ");           // for debugging purposes
 Serial.println(!dir);               // for debugging purposes
 delay (2000); // Straighten
 digitalWrite(TURNBRAKE, HIGH); // stop
}

This might be better for context sake?
