This was an old project done a couple of years ago, but still worth demonstrating it to show how hardware and software can work in a nice fashion, cars these days use a lot of technologies, a controller is the heart of it. The Arduino UNO board is about 11 bucks now, and the LCD is about $14. They can build some nice project around the house, like a water leak detector. Back in the old days, we would be thrilled to make an AM/FM Radio, that might well pave the path for today. Hope kids these days would have the same heart and soul.
