Trouble with uploading neopixel

Post by jerhieb »

Hello. I am middle school teacher that is trying to figure out how to use a APA106 RGB LEDs. (I thought I ordered normal RGB LEDs and they were broke. Oops.) It looks like I can control them by downloading neopixel and using that module. I went through the instructions online that had me type in about 8 commands into my command line, but I can't run a demo because it raises an error when importing neopixel. If I type 'import neopixel' into the shell, it says that that module doesn't exist.

I am using a Raspberry Pi 3 with the goal of programming with Python. I tried the commands on 2 different computers with the same result. I'm sure I am missing somethign. I would love any help.

Thanks.

I just noticed that it was saved for python 2.7 instead of python 3. Does neopixel work in python 3?

Can you link your software setup (what library are you using) so I can assist you better?

My operating system is Raspbian GNU/Linux 9(stretch)

To get this to run, I typed into my command line:

sudo apt-get update
sudo apt-get install build-essential python-dev git scons swig
git clone https://github.com/jgarff/rpi_ws281x.git
cd rpi_ws281x
scons
cd python
sudo python setup.py install

Then, I set up my APA 106. I ran strandtest.py.
First, it said that it can't run because it doesn't have the module neopixel
I was able to find that the module was downloaded in the python 2.7 file rather than python 3.5.
