Raspberry Pi Pico W LESSON 52: Controlling Neopixels in MicroPython

You guys can help me out over at Patreon, and that will help me keep my gear updated, and help me keep this quality content coming:

In this class we will be using the Sunfounder Raspberry Pi Pico W Keppler Kit. It will make things a lot easier if we are working on identical hardware. the link below is to amazon, and is for the identical hardware I will be using in this entire class.

In this video, I will show you how to control a NeoPixel strip using microPython on the Raspberry Pi Pico W. We use the 8 pixel strip from the Sunfounder kit. The concepts we show will be the same for much larger strips, just for larger strips you need a seperate 5V DC power supply.

I am a 15 year old hıghschool student and ı just started doing arduıino, and when ı discovered your channel ın 2 days ı was able to make a traffıc lıght out of leds. Thank you!

I modified my Neopixel desklight controlled with an RPI Pico setup. I now feed a buck converter with a 12V, 1.5A power source. I power the pico and Neopixels separately with 5V from the buck converter. The Neopixel strip is now brighter than it was when the entire strip was powered by the pico.. I have the 180 strip in two sections that are side by side. They have an adhesive back that are stuck to the bottom of a bookcase above my computer desk. The code is very simple. After the setup, I turn on the strip with the code:
delay = 0.004
warm = (255, 100, 40)
strip.brightness(90)
Turn on LEDs
for x in range(180):
strip.set_pixel(x, warm)
strip.show()
utime.sleep(delay)

Thanks for another great lesson Paul. Appreciate all your work in putting these lessons together. I've been playing with a neopixel ring the last few weeks. Amazing, what you can do with these things!

It is a long video. The home work is in the first 6 minutes. Thanks Paul for all you do.
I also discus an alternative to the HSV to RGB conversion for rainbow effects.
At the end I show how to keep your code from freezing on glitchy USB connections.

Hi Paul I am getting AttributeError object has no attribute NeoPixel .
Pix= neopixel.NeoPixel(Pin(pixPin), pixSize)
Can you help because I don't understand why ?

I am really enjoying this series and your other great lessons. I'm wondering what you are using for a sketch pad. I watched your tutorial on OBS from 3 years ago where you link in the descriptions to the HUION HS610. Are you still using that or something else? I am in need of one.

God bless!
