Question: Like the title says i want to control around 30volts of current (multiple LEDs that will be running all at once, added up to about 30volts.) i want to use a micro-controller to control it so i can add some effect to it, the controller will control 4 LED strips which take about 4.5V ea. and a 12V light strip. any help or ideas to control this project would be great

Answer: 
Most micro-controller boards will give you a 0 (LOW) or 5V (HIGH). 5V will turn on the gate of an N channel MOSFET. Even low cost MOSFETS should allow 50-60 Volts from the drain to the source.

IRF520PBF at a common US distributor is 96 cents.
My favourite way of doing things like this is with the good old [ULN2803](http://www.ti.com/lit/ds/symlink/uln2803a.pdf). It's such a simple chip to use, and you can use it to switch high voltage and current, and even inductive loads.

It's available in DIL and SOIC packages.
