I am curious about the use of these [] brackets. My understanding is they are for arrays in processing. I see them now quite often in arduino programs but with no mention of "including" any processing modules. Is there a reference to these brackets in arduino? I would like to understand them fully. Thanks very much.
Square brackets are used for arrays in Arduino (C/C++) and Processing (Java).
Any C or C++ tutorial will provide information on how to use them in declaring arrays and accessing array data in arduino.
Got it. Thanks very much.
