API calls

Unit Name	Route	Data	Return	Description
all	/	{ip:String, port:String}	Code:200, {UNIT_NAME:String, ID:String}	Units will listen on UNIT_PORT until they receive server IP and port for sending values
LEDUnit	/set	{index:String, r:String, g:String, b:String}	Code:200, String	set LED at index to color {r,g,b}
LEDUnit	/set	{r:String, g:String, b:String}	Code:200, String	set all LEDS to color {r,g,b}
LEDUnit	/handleConfigure	n/a	Code:200, String	not implemented, does nothing
buttonUnit, distanceUnit, encoderUnit, lightSensUnit, scaleUnit	/handleConfigure	{end}	Code:200, String	shut down server, no more routes accessible (does not stop unit from sending sensor readings)
distanceUnit, encoderUnit, lightSensUnit, scaleUnit	/handleConfigure	{threshold:String, sensitivity:String, mode:String}	Code:200, String	set threshold, sensitivity and mode

Modes

Modenumber	Modename	Description
0	BOOLEAN	send updates when sensor reading crosses threshold (rising and falling flank)
1	CONTINOUS	send updates when sensor reading changes by more than sensitivity
2	IDLE	do not send updates
