Hi, I'm after some advice. I'm new to electronics and the Arduino although I'm experienced programming so hopefully I'll have that side covered. I've spent the last week playing with the Arduino and I want to start my first project which would be of some use.
I've been doing plenty of research round the net but unfortunately I've got a little confused on one topic: Power. I want to build a Lamp using RGB LEDs so I can display different colours (bit like Philips Hue - I plan to code a small web app just for myself to control it if I get far enough into the project). The two best sources I've found are:
Based on these videos: http://www.jerome-bernard.com/blog/2013/01/12/rgb-led-strip-controlled-by-an-arduino/
In the video the guy uses a 12v battery powered supply, I was wondering if it was possible to replace this with a mains power supply like one below (I'm based in the UK)?
I'd just cut the wire open and have a working power supply (I know I'd need to be careful working with mains power)
The other question is relating to the Arduino needing a separate power supply, is there a way to power both from the same source?
If you have any advise at all I'd appreciate it, maybe a good article or part I should look into. I'm really keen to learn.
