Hey all,
I just started planning for the LED VU Meter project I've been wanting to do for a while now. However, I have many questions as I'm stuck in the design of the circuit while trying to understand how the IC works. I don't want to blindly go in and copy circuits without understanding the theory of the chip.
Last question (for now): I've also seen a lot of people throwing in a capacitor in their circuit. What are they for (other than getting rid of oscillations from the power supply)? Can they be used to make the LEDs "dance" smoother?
Thanks in advance for any advice/help!
P.S. I have attached a picture of the LEDs' specifications which I have bought a while ago (which I plan on using for this project).

- If I have LED which consists of various forward voltage values (e.g. yellow = 1.8-2.2V & pink = 3.0-3.2V), do I need to throw in resistors and have the LED voltage at 5V? This way it'll drop the voltage to the required value instead of burning the LED.
- Can anyone explain me how the voltage reference implemented in the IC work? I read the information in the datasheet in vain.
