Pygame Blink prop

Educational example of pure Python props using pygame.

An educational example which makes a LED blinking and making a sound.

This props uses Pygame and extends ThreadingProp (so it uses multi-threading).

Installation

See INSTALLATION.md and as a good habit is the PyProps folder is /home/pi/Room/Props/PyProps

Dependencies

If you don't install the whole PyProps library, you will have to fulfill the PygameBlinkProp requirements:

PyProps/core/ThreadingProp.py
PyProps/core/PropApp.py
PyProps/core/MqttApp.py
PyProps/core/PropData.py
PyProps/core/Singleton.py

And you will have to install following Python packages:

$ pip3 install paho-mqtt
$ pip3 install PyYAML

Usage

Start main.py script in /home/pi/Room/Props/PyProps/PygameProp/PygameBlinkProp:

pi@raspberrypi:~ $ python3 ~/Room/Props/PyProps/PygameProp/PygameBlinkProp/main.py -s 192.168.1.42 -d

SSH relaunch command

The command to relaunch the prop is :

$ ps aux | grep python | grep -v "grep python" | grep PygameBlinkProp/main.py | awk '{print $2}' | xargs kill -9 && screen -d -m python3 /home/pi/Room/Props/PyProps/PygameProp/PygameBlinkProp/main.py -s %BROKER%
