[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 ...

[Arduino Super Introduction #24] Mini Project: Automatic Lighting | Let's Automatically Turn on an LED When It Gets Dark

In the previous chapter, we used a light sensor to read the ambient brightness as a value from 0 to 1023.This time, we will ...
