Hi
At this time I'm preparing the LED-stripes and the wires for this.
I have cables with 4 wires, colours red, black, brown and orange with a lenght about 90cm. I will solder the red (for Anode) and black (for Cathode) to the LEDs, and the brown and orange are for the push-button. Also I will mark the cables with the country codes (IE, FI and so on). Is this OK for you, for the control group? This cables are free, we have enough of them.
kind regards
Fritz
