Building a water level gauge using MPX5010DP sensor and arduino.

Provide configuration options to enable/disable alarms and govern display behaviour.

The design as of release 1.0.0 implements EPICS style alarms with very low (lolo), low (lo), high (hi) and very high (hihi) limits and behaviours.

1. In deployment, neither high alarm is required, since the only mechanism that would trigger it is during filling, and this would only be beneficial if the display could be seen synchronously with the filling operation which for user1 is not a requirement.
2. Low alarms are useful, but it would be preferable to select whether an asserted alarm applies flashing behaviour or not. Configuration of the trigger level is required.

Release 1.2.0 is unstable due to lack of free SRAM

Compiler warning. Around 200 bytes free of SRAM - but may be insufficient.

Easter eggs corrupt display and leave trailing characters.

The application runs a cycle count, and on special cycles, easter eggs update the display with non-standard information. However, the LCD 16x2 character operations involved overwrite the bottom line, but do not erase themselves afterwards, instead relying on the next information update to fully rewrite the line. This is not working. The side effect can be to leave a trailing 0 to the right of the latest reading, thus erroneously appearing that a spike of an order of magnitude has been seen,

Release 1.3.0 reboots spontaneously.

Observed several times by Nick. Note that the display of the loop counter indicates unexpected behaviour.

Display text modifications to improve clarity.

Requested by Nick Balshaw (user 1).

1. Replace the text label for the average reading. Currently Avg (appears to similar to Aug). Replace by "Av" or "Av."
2. Replace the text label for the fluid type measured. Currently "H20". Would prefer "Water". To gain additional character space would suggest sacrificing parentheses around the units label. i.e. "cm" for "(cm)".
