The result had to be :
- Modular (plug)
- Easy to use
- Not too big.
1/ making the plug:
Due to recycling, i don't have many colours in small wires so, Red == Red, Yellow == Green, Blue == Blue, and White == Vcc. (this will get much more complicated soon ;-))
2/ Soldering to Pins:
On the Plug i want RGB in order so it is Red-Green-Blue-Vcc
But on the LED pins, the order is Vcc-Blue-Red-Green
3/ Drilling holes for the plug and writing RGB+:
"- What the hole!
- Hey, no one is perfect. >_<"
4/ Insulating and testing the plug:
"- Wait, what? you plugged White to Brown, and Red to Yellow ??
- Yes, i did, remember that's recycling, so... i'm using what i can!"
5/ Only and Arduino is needed to complete that project now :)
part 4 pending ....
