New tutorial based on "Arduino Uno"

Hello together,
I allmost made it. A few lessons are still missing.
But I think it´s just the right time to publish my new tutorial, based on an “Arduino” - set.
I have transformed the set, especially I have transformed the chassis.
For that you need a 3-D-Printer, but I think that by now everyone is coming to one somehow.
I hope you have some fun by looking the videos.

Have a nice day

P.S.: My “old” tutorial.
