Arduino ohmmeter or how to connect thermistor to Arduino

Video on how to make a resistance meter, ohmmeter out of Arduino. In this video, I also talk about how to correctly calculate the voltage divider for a thermistor (thermistor). The material is also suitable for other microcontrollers such as WeMos, ESP8266, ESP32.

Очень круто, продолжай!

а вот как измерить сопротивление Rx, не для резистора неизвестного, а для проволоки? просто проволоку ставить?
