I'm working on a project and I'm wondering if I'm powering it correctly. I've never powered anything with a supply other than the Arduino regulated 5V.
My project is a wifi enabled LED light setup. I'm using an Arduino Micro, Adafruit CC3000 breakout board and 25 Adafruit Neopixels. The pixels require 5V and each one draws 20mA average and 60mA peak at full white.
If I want to use one power supply, does it make the most sense to use a 9V supply for the Micro and then use a voltage regulator like an LM317 (or LM350 if I decide to add more pixels) to get 5V for the LEDs? Is there a simpler solution?
Here is my current plan. Please let me know if I have anything hooked up incorrectly! Thanks for reading!!
