I am new here and just started to play with Arduino about 3 weeks ago. Since I have lots of expertise in software programming and some knowledge about micro-controllers, it's really quick for me to start developing useful things on the Arduino platform. I think Arduino is so wonderful invention for us software guys. I spent 2 weeks to make an Arduino board connect with my car through OBD-II port, reading out the data and displaying them on a 84x48 LCD shield. It's great fun! I wrote an article
