This is a great guide! I do have one questions though, I plan to use this power supply (5VDC, 5A variant) for a project containing 176 NeoPixels (WS2812B). In the NeoPixel Überguide supplied by Adafruit(https://learn.adafruit.com/adafruit-neopixel-uberguide/powering-neopixels), the use of a 1,000uF/6V capacitor is recommended when powering the NeoPixels from a wall power supply. Would I still use the capacitor with this power supply or is there one/something similar already built in?
If this is not the correct place to post this question, please let me know.
Thanks! Donna
Luckily, I saw your post when looking for something. ;P For technical support questions, you would want to head to the technical assistance page. However, I can quickly answer this question. =)
Yes, I recommend adding a capacitor to smooth out the power supply output. It's subtle but I briefly linked the WS2812 Breakout Hookup Guide in the suggested reading. In the tutorial, there is some information about adding a decoupling capacitor and resistor to the setup before the addressable leds.
Would the Arduino source code happen to be available?
Thanks, Carl
It depends on the type of addressable LED strip that you are using but yes, I do have the Arduino example code that was used to stress test the WS2812-based LEDs used in this tutorial. You can find it in my gists here:
It uses the FastLED library so make sure that you install it before compiling. =)
