Q: How execution time of code instructions influences signal between Arduino and DHT11?

Artur KrushI am exemining code for DHT11 from CircuitGeeks, variant without using lib. The problem is a mismatch between DHT11/DHT22 protocol and signals, which are read from sensor in scetch. Despite this, sketch is working and I would like to find out how. #define DHT11_PIN 12 unsigned long TON_TIME = ...
