I use technology like this is develop the construction and learning skills with Jason and seniors.
The technology is called LittleBits Electronics and it like playing with Lego. On the above photo are colour coded LittleBits blocks. The central one is an Arduino Computer with inputs on the left and outputs on the right. It is a very simple demo where the dimmer on the left is sensed by the Arduino computer and delivers to the bar LED array on the right a pattern corresponding to the value on the dimmer. This modules just clip together using magnets and it is very easy to use. See my projects under ozBerry or projects with Jason for more.
