Sorry for such a noobie question, but I've only had my Aurduino for a month or so and don't want to fry it already! I'm working on a tutorial to program an RGB LED strip. The strip is 5m long and I want to use the Uno to write a program and use all 5m. I have the board setup identical to the tutorial with the transistors. In one of the captions it says I can use an external 12v source. I have a 12v 2a wall plug that I'd like to power this with. It says to connect the +12v of the wall plug to the Vin on the LED strip and ground to the arduino/mofset.
Does that mean any of the ground pins on the board? It's the /mofset that got me, I don't know if that means a specific ground pin or not.
Here's the tutorial I'm working on:
