So I've been following this tutorial for a ambilight project using Arduino. I don't know much about wiring so I have a few questions about that. Everything seems pretty straight forward with wiring with the exception of two things. Another thing to note is that I'm not confident in my soldering abilities so I want to try and achieve this without soldering if that is possible.1) 10:18 in the tutorial says to "have ground from the power supply go to the Arduino. What would be the best way to accomplish this? Could I just take one of these and cut off one of the ends? Attach the pin to the Arduino and strip the wire on the other side to attach to the power supply. Would this work out?2) 18:51 in the tutorial says to "Plug the Arduino Pin 10 into the LED strip data line." Could I use those male-male breadboard cables that I linked earlier for that? The Data wire on the LED strip is connected to a 3 Pin. I looks like this Would it work if I took 1 end of the cable and plug it into LED 3 pin on the data/middle pin only and then plug the other end into pin 10 of the Arduino?3) The next question I have is about common ground. The tutorial says (10:38) to make sure the Arduino and LED strip have the "same ground potential" or else I would have data errors. Would I achieve this common ground by having both of them be attached to -V on my power supply? Is that all I need to do to have common ground between them?4) My last question is about the power supply itself. Here's my power supply. On my power supply I have two -V's rather than the one -V the tutorial has. Which one would I attach the wires into?Thanks for having the patience to read all of this. I'm very new to this and I want to surprise my brother for Christmas. via /r/DIY http://ift.tt/2AZXfJZ
