a few days ago I found this as an instruction for an cheap DIY ambilight for pc and started with it as my very first small tech-project. I bought an Arduino Nano from a local hardware seller, and some LED stripes (WS2811) from ebay. Accidently I bought stripes that need 12V as power supply. Is it somehow possible to power these just with the Arduino and its 5V USB-input without any additional power supply, or do I have to buy something else?
A friend of me has suggested to use somethink like this (SIM1-0512 SIL4) - would it work?
Also, I would be happy for any other advice that could help me.
I hope anyone can help me.
