How to power an LED stripe and the Arduino Nano with the same power source

Using Arduino Project Guidance

Hi @Grumpy_Mike,

thanks for your reply.

Here's the diagram: https://github.com/Scaronthesky/smart-kids-kitchen/blob/master/docs/SmartKidsKitchenBreadboard.fzz

Some follow-up questions:

  1. So it's basically possible to power the Arduino and the LED stripe with the same power source?

  2. Why do I need the capacitor and the resistor? EDIT: What type of capacitor (polarized / not polarized) would I need?

  3. The LED strip has 60 LEDs/Meter and is just one meter long. I'm planning to cut the strip into several parts to install them in the oven, the microwave and as a kitchen light. The separate parts will be connected by normal wires.

Thx!
