If you are looking for ideas how to make your project catchy, consider using different way of presenting data. Instead of using LCD, LED displays go with analog gauge. You can use analog meters for that, which use may be a bit complicated as it needs analog voltage. In digital electronics we want it to be digital controllable.
TheRengineer suggests using stepper motor driven gauge. It is based on X27.168 stepper motor which has a needle attached to its shaft. It can be easily driven with Arduino or other micro. It is mounted on convenient breakout board with 6 pin connection header. Of course the library is here for instant use. He’s done really good job making it move smooth and fast.
