Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Struggling to make a file run from boot
I'm very new to all things pi, or really electronics in general, but I'm enjoying the learning process so far. I'm trying to add a power button to my Pi4, using the GPIO zero library, but can't quite get the last step to work. I've set up my button on the GPIO3 pin and the ground next to it. For now I'm just trying to get the simple_shutdown working, so after changing that script from GPIO21 to 3 I've saved it, changed it's permissions using 'chmod a+x', then added the following into /etc/rc.local: ````echo '~pi/shutdown-press-simple.py &' >> /etc/rc.local

Startup/shutdown problem
You need a power switch and a reset switch. See here for instructions https://github.com/TonyLHansen/raspberry-pi-safe-off-switch/

Raspberry Pi, InfluxDB, Grafana, Docker
It was a bit tricky to get CPU temperature of a host machine (Raspberry Pi) from within the running docker container. This Issue on GitHub has helped me :

What can we do with python, exactly?
No. The pi 4 is not a microcontroller. However, I would recommend gpiozero for a regular pi4

mqtt-gpio: A service which connects MQTT topics to Raspberry Pi GPIO pins
I run it in K3s on Raspberry Pi OS. The service is built on gpiozero so should work on other devices. It is a very helpful building block in my DIY home automation system. It's a general purpose connector so it can be configured for many different uses. At present I use it to:

GPIO Programming on the Raspberry Pi: Python Libraries
Gpiozero is already installed in the current Raspberry Pi OS - if not, just run python3 -m pip gpiozero. The source code files can be accessed on Github. The official documentation on readthedocs.io provides rich information and plenty example code.

Build your SO their own "attention button" this Valentine's Day
The code we will write will be in Python. Let's start with just getting the button to register. We will be using the gpiozero library to do this:
What are some alternatives?
OctoPrint-Enclosure - OctoPrint Enclosure Plugin
pigpio - pigpio is a C library for the Raspberry which allows control of the General Purpose Input Outputs (GPIO).
shutty-a-shutdown-timer - Shutty is a shutdown timer for your Windows PC, feel free to use it!
WiringPi - Gordon's Arduino wiring-like WiringPi Library for the Raspberry Pi (Unofficial Mirror for WiringPi bindings)

tkgpio - A Python library to simulate electronic devices connected to the GPIO on a Raspberry Pi, using TkInter.
Adafruit_PowerBoost_SaveShutdown - This project is a save shutdown for the Adafruit Power Boost 1000c. You can use this circuit to delay the power-off, after the user switched the device off. Usefull for e.g. Rasperry Pi.
pi-mqtt-gpio - Expose GPIO modules (Raspberry Pi, Beaglebone, PCF8754, PiFace2 etc.) and digital sensors (LM75 etc.) to an MQTT server for remote control and monitoring.
Raspberry-Led-Power-Button - Raspberry Led Power Button
WiringPi-Python - Unofficial Python-wrapped version of Gordon Henderson's WiringPi version 2.
w1thermsensor - A Python package and CLI tool to work with w1 temperature sensors like DS1822, DS18S20 & DS18B20 on the Raspberry Pi, Beagle Bone and other devices.
systemd-gpio - A systemd unit template that does things when gpio events happen.
