Start/Stop streaming

	=== Start/Stop streaming ===		=== Start/Stop streaming ===
	~~// TODO fill out how~~ this ~~works~~
			The streaming PC uses OBS to stream, and there is a python websockets library which can control it. This library and a serial command interface known as CmdMEssenger is used to communicate with an Arduino Mega so the Mega can indicate signals to control OBS through a small python script. CmdMEssenger implements a messaging protocol to trigger functions via commands sent over Serial.

			The Arduino Mega is effectively a slave to a python server on the streaming PC. The Arduino will set and clear bits in an array which is communicated to the streaming server via the server polling the Mega. The server is continuously polling the Mega and performs actions based on it's state and the information in the status array.

			A user pushed a green button on the cabinet front panel to start (or stop) streaming. The Mega debounces and latches the button press and sets status bit 11. The stream server reads this bit which determines is a button press occurred. If the machine is streaming, the steam will be stopped (and the scene in OBS changed to "Not Live"). If the machine is not streaming, the stream will be started and the scene in OBS switched to "Live".

	=== Activity ~~Sensed~~ ===		=== Player Activity ===
	~~// TODO fill out how this works~~
			A PIR sensor is attached to the cabinet under the player controls. The sensor feeds data back to the Arduino Mega which monitors the signal for movement. As movement occurs, a timer is reset and status bit 12 is set to 1. If the timer is not reset within 15ms, the Mega sets status bit 12 to 0, which tells the stream server to stop the stream
