Hi,
I'm looking to build something to monitor the following things on my Impreza,
Water temp
Oil Temp
Oil Pressure
Ideally i would like to be able to display the actual values on a backlit lcd display and if possible include high and low level alarms on each parameter, ie if the oil temperature goes too high or the oil pressure goes too low.
or
This might be a bit easier, a series of led's that could be pre-set to come on at a given value, after all i only really want to know if something is wrong i dont want to be looking at a load of gauges all the time.
If i was going to go with this idea i'd be looking for something like this, could possibly use tri-colour led's?
Water Temp; An led that stays on until the water is up to a pre-determined temperature possibly yellow? Then goes green between two levels and then Red if it goes above an upper limit.
Oil Temp: Same idea as the water but with different settings
Oil Pressure: Again the same idea but would be in reverse this time as it would start out Red then turn green once the engine was started, and oil pressure was up, doubt i'd need to worry about and upper level for this one.
Only problem now is where to start
Any help much appreciated
Many thanks
Kenny
