Thank you for reading my question, I'm newbie here, and I've already downloaded the Arduino IDE and been reading the tutorials, and I would like to explore some ideas in creating gadgets with LCD Touch Screens. Is it necessary to have a breadboard to test out your ideas, or can I used shields to apply to the LCD Touch Screen to test out my program. I'm interested in creating touch screens applications that users can use. I've been reading some post regarding arduino simulators, but most of them are for Windows, and I have a Mac-Mini. Thank again and God Bless....
