After two days of developing we get first Results. Step by step each group built the outer hull and the inner electronic circuits.
We learned that it is important to test every small part of the electronic circuits, because you never now, if any transistor is broken, or the circuit doesn’t work as expected.
See a small video of a circuit with two multiplexer controlled by an Arduino, that can switch on and off all rgb channels of 3 light stripes.
