Should I be using capacitors?
Finally, will the RF interference generated be a significant problem with my Bluetooth module? LM is a switching regulator.
See the datasheet, p. If you only need to step down from 9V to 5V, and don’t need high efficiency.
You may choose linear regulator. With it you don’t need to worry the switching noise with switching regulators. You should use bypass capacitors to make your power rail more quiet. Generally, the regulator’s datasheet will give you the typical application circuits, like this LMp. If you don’t have so many capacitors with different values, you can parallel small capacitors to get a bigger one, such as if you have many nF capacitors, you can parallel ten to get 1uF.
However, I’m not sure how to wire this into my breadboard: Where does the feedback pin go? Mateen Ulhaq I don’t own a lm2557 inductor, diode, or a uF capacitor, though. I think I’ll just use a linear regulator instead. If I wanted to use the LM, would I need to buy capacitors?

I currently have 3x pF, nF, uF. For LM, the datasheet recommends 0. Generally, the bigger the better. Bigger capacitor has better filterring capability.
