 * Example configuration of a DS18B20 device on an Arduino serial bus.
 * Open drain configuration allows communication by simply connecting the bus
 * line to:
 * a) the UART RX pin as well as the TX pin.
 * b) the UART TX pin only, while the single wire half-duplex mode is enabled.
 * An external pull-up should be added anyways.
