C

C is a programming language designed by Dennis Ritchie at Bell Labs. C is very widely used, straightforward, and can be compiled to a number of platforms and operating systems. C is an imperative language, with a small number of keywords and a large number of mathematical operators. C is also a very low level programming language, which means it can communicate directly with hardware.

Termostat postavený na platforme Arduino s Ethernet shieldom Wiznet W5100 / modulom Wiznet W5500. Využíva teplotný senzor DS18B20 na OneWire zbernici. Arduino riadi výstup - relé na základe rozdielu cieľovej a nameranej teploty so zohľadnením hysterézy. Thermostat built on the Arduino platform with Ethernet shield Wiznet W5100 / module Wiznet W5500. It uses the DS18B20 temperature sensor on the OneWire bus. The Arduino controls the output-relay based on the difference between the target and measured temperature, taking into account the hysteresis.
