If data is available, we can use " Wire.read()" to get one byte at a time from the buffer and store it in a variable for later use. We can use " Wire.available()" to check to data. When the slave starts sending the requested data, the Arduino will store them temporarily in a buffer. The first parameter ("8") is the slave device address, and the second ("6") is the quantity of data (in bytes) that we want from the slave. In the loop(), we use " Wire.requestFrom(8, 6) " to ask a slave device to return data. With this, the Arduino will join the bus as a slave, listening to address "8". ![]()
