*Each bullroarer node has a base address ''/br/num'' where ''num'' is in 1-21. *They can send 4 messages:**''/br/1/range'', integer, 0-1024. Analog sensor reading from ultrasonic rangefinder from 0-1024. Sent every 200 ms (so 5 Hz refresh rate).**''/br/1/limit'', integer, 0 or 1. State of limit switch, sent . Sent when button is pressed or released. Switches are active low, so the value is 0 (LOW) when the button is pressed, 1 (HIGH) when the button is released.
**''/br/1/relay'', integer, 0 or 1. State of motor control relay. Sent when relay state changes. Relays are active low, so a value of 0 (LOW) means the relay is on, 1 (HIGH) means the relay is off.
**''/br/1/config'', integer, integer, integer. Sent when requested.
***First value is auto mode, 0 for "off", 1 for "on".
***Second value is max range, 0 - 1024. This is a threshold value for the lower limit of bullroarer travel. When in auto mode, a sensor reading larger than this value will trigger the relay to turn the motor back on and raise the bullroarer.
***Third value is cycle timeout, 0 - max long int. In Sets the amount of time the bullroarer waits at bottom before starting motor, the "rest time". Only works when in auto mode. They can receive 6 messages:**''/br/1/relay'', integer (0 or 1). Turns relay on or off. Relays are active low, this so a value of 0 (LOW) means the relay is on, 1 (HIGH) means the amount relay is off.Configuration messages. The following three messages change run-time behavior of time a node in automatic mode:**''/br/1/auto'', integer (0 or 1). Sets automatic mode. 0 for "off", 1 for "on". **''/br/1/max'', integer, 0 - 1024. Sets the threshold value for the system lower limit of bullroarer travel. When in auto mode, a sensor reading larger than this value will wait after threshold is reached before turning trigger the relay to turn the motor back onand raise the bullroarer. **''/br/1/timeout'', long integer, 0- max long int. This adjusts Sets the amount of time the bullroarer waits at bottom before starting motor, the "rest time" at . Only works when in auto mode.**''/br/1/write'', integer, 0 or 1. Writes the current runtime configuration (auto, max, and timeout) to the bullroarer's EEPROM. This will save the current settings for next startup. Otherwise they are lost. **''/br/1/config'', integer, 0 or 1. Sends the current runtime configuration for the bottom fo bullroarer to the cyclehost computer.
