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. Wire.read() None The next byte receive

void setup() {
  Wire.begin();              // join i2c bus (address optional for master)
  Serial.begin();            // start serial for output

void loop()
  Wire.requestFrom(2, 6);    // request 6 bytes from slave device #2

  while(Wire.available()) {  // slave may send less than requested
    char c = Wire.read();    // receive a byte as character
    Serial.print(c);         // print the character
