I bet almost everyone here at the forum has heard about the Arduino and how much fun and how useful it can be to model railroaders and to other hobbyists.
The price is no issue at about 3,- £$€. But not every hobbyist has affinity with electronics or with software. To some the initial hurdle can be just too steep, even while there may be an interest to get started with Arduno and to try things out.
That is where the plan arose to do a series of articles and videos titled 'Fun with Arduino', aimed at anyone who is not an electronics or IT specialist (yet ).
The first two articles, both with video, are out:
Fun with Arduino 01 Getting Started in 6 Easy Steps.
Fun with Arduino 02 Digital Input and -Output
(Language is English)
