Power options for nano

[km1noidea]

Hi, any help is appreciated. I am running a little project but it’s my first one.

I am not sure how to power the Arduino board, 2 (5mm) LEDs (constant glow), and a SG90 servo (sweep with stops, already programmed).

I know that some people recommend to run the servo power and the Arduino board power separately, but I’m not sure how to wire this or what power sources to use.

Below are specs for each, the LEDs are very close to what I have and I only need to run 2 of them at constant no flicker glow.

If anyone has a diagram for what to wire and how (preferably the really beginner version), and or suggestions on battery power source options that would be wonderful! Thanks in advance.

Use a wall wart or battery pack and connect the + to the servo VCC. The LEDS can be pin powered. Use either a wall wart to power the Arduino via USB or battery pack to the Arduino VIN pin. Connect all grounds in common.

5 to 6v servo power supply.

• Power the Arduino with the power jack, 7 to 9v or via the USB (5v) connector.
