Programmable Christmas Tree Star

banner

Bring some Raspberry Pi based festive cheer to your Christmas this year with the ModMyPi Christmas Star and bring your tree to life!

What's in this repository

This repository should be used by cloning the repo first using

git clone https://github.com/modmypi/Programmable-Christmas-Star

Which will give you a copy locally.

Inside there is a script called star.py which contains a GPIO Zero compatible code allowing you to simply create and use the Star with only a couple of lines of Python.

To switch on the Star you can use:

from star import Star

star = Star()

star.on()

There are several example files to shouw you what can be done with the star:

Example files

  • all_on.py - turns on all of the LEDs.
  • in_out.py - blinks the inner and outer ring of LEDs alternately.
  • random_leds.py - turns on and off all the LEDs
  • slow_walk.py - slowly walks around the LEDs increasing pace until they can't go any faster.
  • twinkle.py - a pulsing walking pattern around the LEDs.

These files can all be run using: sudo python3 name_of_example.py

Star Commander

You can follow the tutorial on our website and learn how to use the Star Commander script.

This script allows you to command how the start glows from the command line over SSH. There are 4 built in modes (plus an off switch) to control the star with ease without having to climb the tree and attach a monitor each time.

Let us know how you get on with the Star and we hope you have a Merry Christmas.

programmable-christmas-star's Issues

LED always off

Hello,

Does someone know the reference of LEDs used to make the star ? One on my Star is dead, I'd like to replace it if possible.

Here is the all_on.py example :
PXL_20231219_171317185

Thanks

Scripts fail with Python 3.7 and gpiozero 1.5.1

Hi,

I was just giving the christmas star a spin and am running into several issues.

Only all_on.py works but throws alot of errors.
The other scripts in_out.py, random_leds.py, slow_walk.py, starcommander.py and twinkle.py exit out fast and have no effect on the LEDs.

I have Python 3.7 installed.
The gpiozero package installed via pip3.

pip3 show gpiozero
Name: gpiozero
Version: 1.5.1

Taking twinkle.py for example.

Is there some compatibility issue with the scripts and later versions of python3 + the gpiozero package?
