<h3 ><span >Welcome to another Arduino Tutorial.</span></h3><p >Using Button and LED we will learn what is PWM (Pulse Width Modulation) and make examples for controlling the LED brightness using PWM.</p><p > 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.</p><p >For this tutorial I have made a short and informative YouTube video:</p><p ></p><div class="se-component se-video-container __se__float-none" contenteditable="false" style="width: 100%;"><figure style="width: 100%; height: 56.25%; padding-bottom: 56.25%; margin: 0px;"><iframe frameborder="0" allowfullscreen="" src="https://www.youtube.com/embed/YE5kaMhx3hY" data-proportion="true" data-percentage="100%,56.25%" data-size="100%,56.25%" data-align="none" style="width: 100%; height: 100%;" data-index="0" data-file-size="0" data-origin="100%,56.25%"></iframe><figcaption contenteditable="true"><div>Watch me ^</div></figcaption></figure></div><p ><span >This particular video was made in Hebrew, therefore I will be happy to answer any question in the comments below - </span><strong >Do not hesitate</strong><span >. </span></p><p >I hope you will find this tutorial useful and meaningful.</p><p >Roy.</p><p > </p><p > </p><p ></p>

Pulse Width Modulation

PWM using Arduino mega board, LED and a button. Elementary project but important to understand more advanced IC.
