Arduino as 1-wire slave

The project is to write a sketch for an arduino that makes the arduino act as 1-wire slave. Specifically it shall act exactly the same as a DS18b20 device. The project is finished when we have: 1) an instruction how to connect 2 arduinos with each other 2) one arduino has to act as a 1-wire master 3) the other arduino has to act as 1-wire slave 4) sketch/libraries for the Slave-Arduino that enables us to set a temperature and a ID for the emulated DS18b20 5) sketch for the Master-Arduino that enables us to read out the temperature value of the slave arduino in the serial monitor
