I accidentally burnt the Neopixel while soldering them. but the white LEDs are fine so here are some pictures.
As it gets very messy with the wires once a prototype work and I have no talent for soldering everything together with the certainty that it will still work after that. I decided to keep everything on the solderless breadboard. I did some quick visuals of how the board could be assembled with the Arduino and LEDs strip.
First some pictures of the mess:
The quick visuals (Diego cleaned them with illustrators for the presentation):
putting the whole board together was tricky as someone has to hold it up while I was reconnecting the LEDs etc.
And it worked!!!!!!!!!!!
