Interactive Intro

The ability to send data from MakerPlot-J to a connected controller or read MakerPlot-J from the controller allows interactive control such as turning devices on or off, setting setpoint, setting drive values, etc.

From MakerPlot-J, Event Code can send data such as when a slider is adjusted:

!send [sldDrive]
drive=Serial.parseInt();

Or have the controller request data and accept the returning data:

Serial.println("!read [sldDrive]");
drive=Serial.parseInt();

Please see Controller Interactive Use for more information.
