As I mentioned on my previous post, I got an Arduino kit to start experimenting with the platform and eventually interconnect it with the Snap Circuits so that my grandkids and I can have fun building some cool projects. The kit includes an Arduino Mega2560 board and a bunch of components that can be used to build a variety of projects.
It is pretty easy to get started with the Arduino platform. You install the Arduino IDE, plug in the board to your computer using the USB cable, and boom! you are up and running in minutes. I am using the new version 2 of the IDE, and so far it has been very stable.
