Transmit a structure or array with just one "write" if you need to transmit more data. I read about,read() Description. Reads a byte that was transmitted from a slave device to a master after a call to requestFrom() or was transmitted from a master to a slave. read() inherits from the Stream utility class. Syntax. Wire.read() Parameters. none. Returns.
