 The first command stops all currently running `pigpio` daemon processes. The second command disables the daemon, so that it will not start again if you reboot.
 
 2. You will need to create a new `udev` rule. This creates a symlink for a given camera, plugged into a specific USB port, and allows the Java code to consistently communicate with the camera. An example `udev` rule is given in this repo (`83-webcam.rules`), but will need to be modified to your specific device.
