Why is my sketch unresponsive?

Tutorial. New people often ask Why is my sketch unresponsive ? The code example below creates a 63ns pulse on pin D12 every time the loop( ) function starts. The sketch also toggles the state of pin D13 every 500 milliseconds. The accompanying oscilloscope trace depicts what is happening. #include <Wire.h> #include <hd44780.h> //main hd44780 header #include <hd44780ioClass/hd44780_I2Cexp.h> //I2C expander i/o class header hd44780_I2Cexp lcd(0x27); //macro to generat…

This is another approach to explain what blocking/non-blocking coding is.
Maybe this can be integrated into the tutorial of user @ec2021

Millis() instead of delay and loop() instead of for-loop

One of the most frequently asked questions by beginners is how to handle delays and for-loops in loop() without blocking other functions. In this thread I like to publish some small sketches do demonstrate the use of millis() instead of delay() and how to implement the functionality of a for-loop in loop() without blocking. The examples are ment just to improve understanding of the methods not to solve specific problems. They may not even be "best practice" in all aspects ... Improvements and…
