| Description | Called when data is available. Use one of the read() methods to capture this data. The serialEvent() can be set with buffer() to only trigger after a certain number of data elements are read and can be set with bufferUntil() to only trigger after a specific character is read. The which parameter contains the name of the port where new data is available, but is only useful when there is more than one serial connection open and it's necessary to distinguish between the two. | ||||
