## Article

Project describes basics of thermostat and its implementation with Arduino and Ethernet shield Wiznet W5100. The program implementation for the project can be found at:?**<https://github.com/martinius96/termostat-ethernet/>**The implementation contains programs for the static / dynamic IPv4 address assigned to the Ethernet shield. The thermostat is only intended for indoor temperatures! (above 0 ° C), to which the system logic is adapted. It is possible to replace an existing room thermostat with a thermostat, it is possible to temporarily replace a thermostat in a refrigerator, maintain a constant temperature in a terrarium and the like.
