I was looking for a project like normal door bells where after pushing the push button, the melody will start and automatically stop and LEDs rhythmic light up. However, none of the available projects on whole internet was complete. Some had only the push button the automatically melody off, some had LED without circuit design. I ended up to this:<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/3pBeUy6pXwQ" 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>Arduino Door Bell With Push Button and LED</div></figcaption></figure></div>I guess there will be people searching similar projects.

You need to copy paste the &#34;main code&#34; in one tab. Then open a new tab, name it as pitches.h and copy paste the content from our pitches.h file (otherwise you'll receive error related to pitches.h). Then normally proceed. Here is a screenshot (if you can not see the screenshot, then look at <a href="https://github.com/AbhishekGhosh/Arduino-Door-Bell-With-Push-Button-LED">my Github project</a>'s <a href="https://github.com/AbhishekGhosh/Arduino-Door-Bell-With-Push-Button-LED/blob/master/how%20to%20compile%20sketch.png">how to compile sketch.png</a> illustration).

Arduino Door Bell With Push Button LED

Arduino Door Bell With 3 LEDs

Arduino Door Bell with 3 LEDs

Like normal door bells, after pushing the push button, the sound automatically stops after a time and three LEDs rhythmically glow.
