Tell us about yourself!
I used an Arduino Nano powering the led strip using usb power and it seems to be working fine. Is that all right?
I am using the following strip: http://www.amazon.com/ALITOVE-WS2812B-Individuall...Isn't 12v too high? Some projects only use 5v. Also, can you explain how exactly I connect an external power supply to the arduino? I have only worked with usb powered arduinos in the past. Doesn't the dc power adapter look like this? http://www.amazon.com/Etekcity-GD-001-12V-Power-A...Do I need some type of adapter/convertor to be able to plug a wire into it and connect to arduino pin 3?
What kind of 12v power adapter should you use and how do you connect it to the arduino nano? Please explain :)
Can you explain how one would do this please?
