Building eletronic air suspension manometer. Need help & info

Projects General Guidance
1

Hello, my name is Vilius, i'm 21, I am from small country in Eastern Europe called Lithuania.
I am building an air suspension for my car, and I want to change analog manometers to the digital ones. One that I like, is Dakota Digital air gauge, but it is expensive (~300$), so I am thinking about some alternatives :slight_smile:

So this is the Car:

Here are similar to ones I'm using now:

What I think of building myself of:

The problem is, I know nearly nothing about electronics. My knowledge ends at connecting wires, finding + and -, and i've connected a few relays in my short life. I also know how to read basic wire schemes, that's it.

So what I need is just a simple funcion - i want 16x2 lcd to show me pressure of air bags in all 4 corners in real-time. That's it. I dont need to control valves, adjusting right height, or any of those fancy things that every kid wants from air suspension.

So as much as i understand, I need Arduino (would Uno be enough for task like this?), some kind of 16x2 LCD, 4 pressure transducers (system pressure is 10 bar, which is ~150psi, so i assume i need 150-200psi transducer?) http://www.ebay.com/itm/Pressure-transducer-or-sender-200-psi-stainless-steel-for-oil-fuel-air-water-/251409770867
And that's where my knowledge ends.

So what i need is to know, if that's possible to do for me, would it be very hard, what other pieces do i need to buy, and if someone could help me with the coding after I buy all of the stuff? I can pay if needed, but I warn you, that I am student, so i don't have a ton of money :slight_smile:

Thank you for attention,
Vilius

You might want to consider getting your feet wet in basic electronics/programming before you do your first real project :slight_smile: . As far as the software goes, it seems like a completely reasonable project.

This is a good first real project.

But CWashburn is right, take the time to go through some tutorials.
You'll see that reading a analog sensor( your transducer) and using a 16x2 LCD are both included
In most tutorial series so after you complete some you will be able to do this easily and a also get ideas
To do a lot more.
Oh and that transducer will be good to use.

Have fun and nice ride!( I like wagons)

Did you ever get your programing figured out?
