Serial.write() writes binary data to the serial port. This data is sent as a byte or series of bytes for example: Serial.write(buf, len) where: buf: an array to send as a series of bytes len: the length of the buffer The problem is, how do you calculate the length (len) of the buffer (buf)?

You don't calculate it - you already know it.
