[Arduino Super Introduction #33] Changing Brightness with PWM | Let's Adjust LED Brightness with High-Speed On and Off

In the previous chapter, we stored the current state in a variable and switched the LED operation mode every time the button was pressed.The signals sent to the LED so far have been of two types: HIGH ...
