Using DSLR as a webcam on Arch/Manjaro Linux

Many thanks to Ben Chapman and his blog post How to Use Your DSLR Camera as a Webcam in Linux.

v4l2loopback is a linux kernel module that allows you to create "virtual video devices". Kernel modules are pieces of code that can be loaded and unloaded into the kernel upon demand. They extend the functionality of the kernel without the need to reboot the system.

Supported Cameras

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

	#include <MIDI.h>
	#include <SoftwareSerial.h>
	#include <DFPlayer_Mini_Mp3.h>
	#include <math.h>

	SoftwareSerial mySerial(11, 10); // RX, TX

	MIDI_CREATE_DEFAULT_INSTANCE();

	bool isMp3Mode = false;
