<p >Hello everyone,</p><p >Don't you want to have nice and cool earrings when you go out at night or for parties? I would, that's why I made Arduino LilyPad-controlled NeoPixel Earrings. :) These earrings don't just light up. They have several different animations and colors.</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/7B3Uz_2O9Rw" 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 Lilypad Controlled NeoPixel Earrings</div></figcaption></figure></div><p ></p><div id="gallery"><img id="gallery" src=https://projects.arduinocontent.cc/54827ff9-41de-4369-b13f-9497ddd28e36.jpg /><figcaption> </figcaption><img id="gallery" src=https://projects.arduinocontent.cc/71168c9c-76b1-4b2f-98df-fe1584d77506.jpg /><figcaption> </figcaption></div><h3 >Step 1: Circuit Diagram</h3><div id="gallery"><img id="gallery" src=https://projects.arduinocontent.cc/56dbc3a7-0410-48f6-b2dd-d2669beaca7e.jpg /><figcaption> </figcaption><img id="gallery" src=https://projects.arduinocontent.cc/e9c35fb9-c441-4a42-be49-177814bd5b8e.jpg /><figcaption> </figcaption></div><p >We will start the project by loading code into LilyPad first.

Arduino LilyPad Controlled NeoPixel Earrings

Hello everyone, I made Arduino LilyPad controlled NeoPixel earrings. :) They have several different animations and colors.
