greeting kind heated person. I have a trouble with my source code it couldn't process the fuzzy and then the code won't loop anymore every time I use the LCD library and output it on LCD. note I'm using LCD 16x2 with i2c, I've been using a simple program to output it on LCD without any sensor and fuzzy and it can. please help me kind-hearted person
