Pulse Width Modulation

Welcome to another Arduino Tutorial.

Using Button and LED we will learn what is PWM (Pulse Width Modulation) and make examples for controlling the LED brightness using PWM.

PWM is a principle/method of reducing the average voltage delivered by an electrical signal. This principle has many applications in our everyday life such as: motors, computer fans and even sewing machine. To sum it up, we will meet this elementry but important principle where the user needs to control the amount of voltage/current/power into the machine.

For this tutorial I have made a short and informative YouTube video:

This particular video was made in Hebrew, therefore I will be happy to answer any question in the comments below - Do not hesitate.

I hope you will find this tutorial useful and meaningful.
