Hi , i have a couple of questions , firstly im a newbie so please be gentle.

1. I purchase the a 60 LED 1m SMD 5050 light strip thing and controller which is great but i want to take and cut down the strip into sections of 3 lights and control/change each.
Im realistically looking to have several of these maybe changing colours over the day i dont even really need to connect them to the arduino mega i have , just want to light several small areas.


If you don't connect them to a microcontroller (like an arduino) you can't have them change colors over the day, unless you did some nifty wiring with traditional ICs. I'd suggest getting a cheaper arduino if you want to do a permanent mount (or a bare atmega328). Good luck though.

So say i just want to power it from the PC , i can use a spare molex power cable and grab the 12v and ground and wire it to a power connector to attach to the colour changing box without doing anything else?
Is it really that simple?

I was worried that the power from the computers psu or should i say current would be too much.

Thanks for your help.

I also wondered if anyone has played with these before , even taking one of the leds and connected it to the arduino single led at a time?

Yes  :)
It is the voltage that is important, the current capability of a power supply is just that, a capability, what it can supply if called to do so not what it will supply.

Do you or anyone know the best places to find teaching electronics stuff , i want to learn more but cant seem to find any decent basic's guides etc explaining this sort of stuff.
