Hey, I'm trying to build a Dehydrator with Arduino as my first self-sufficient Arduino project (go easy on me :'D) and I wanted to use a KY-040 to set a temperature value which is also printed onto an LCD. Everything works except for the recognition of turns from the rotary encoder and accordingly …

So I figured it out. The worst flaw was the solltemperatur = 0; part at the beginning of my loop. It basically resettet the set temperature value to 0 immediately so no wonder that it wouldn't rise. I redirected this part to the setup. To get it to work i had to set the Millis in the non blocki…

So have you tried printing to the serial monitor when the code is also suppose to write to the LCD?
