I'm new to circuit building and I thought I should ask about this before I go and destroy my components
Basically I have a 9v, 2 amp supply for my project which is being used to power a servor (operates between 5-7v) and some distance sensors (5v). The circuit I have built uses the input 9v and the uses a 6v voltage regulator to step it down; this also happens on the other line, taking the 9v down with a 5v voltage regulator. Is this the way to do it or should I be using reistors to do this?
If I should be using resistors, could someone be kind enough to tell me how I should implement them? I love doing these projects but unfortunately have most of my time consumed by my degree so any help would be awesome

Yes for regulators, No for resistors.
The voltage drop using resistors will vary with load current, therefore no regulation.
Thank for the speedy replies! The main reason I was concerned as the regulator lose the excess voltage via the heatsink, won't this be a problem? Also bearing in mind that I'm taking another supply of the same 9v one and making it 5v. I have the feeling it will lower the amperage of the circuit as it dumping loads out as heat If not, awesome!
It depends on what current the arduino is drawing. Just by itself it draws about 40mA plus any current it is sourcing to drive LEDs. With 9V input your arduino board should be good for at least 400mA so it should not be a problem.

No you are getting confused. Amps flow volts push, the heat dissipated has nothing to do with it.
If not, awesome!
