A few years ago I got a small jukebox with a radio, CD player and some lamps. After only a short time I converted the jukebox to a multimedia PC. But even this one was just standing around most of the time.In January 2020 I discovered the Volumio program for the Raspberry Pi. I installed it on my RPi and was thrilled! Soon I had the idea totake out my jukebox and rebuild it again. Since I have also gained experiencewith the Arduino and NeoPixel, the lighting of my jukebox had to be modernized.I removed the existing lighting and installed 31 NeoPixels. I wrote some lines of code for the Arduino and the LEDs lit up.<figure><img src=https://projects.arduinocontent.cc/9b487a77-1cff-47f0-8a96-99c41befb32b.jpg /><figcaption>Jukebox - All lights on</figcaption></figure>Step by step new effects were added and there will certainly be more.<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/El3Prb491OA" 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></figure></div>Then there was the Raspberry Pi with the Volumio software. Since the sound was very weak via the internal sound chip, I added a HiFiBerry Amp2. Now I could connect my old external speakers and enjoy the music.Then I started to rewire the six buttons and two knobs of the jukebox and use the buttons for control tasks:<ul ><li >controlled shutdown of the Raspberry Pi</li><li >switching the lighting on/off</li><li >selecting the lighting effect</li><li >... more to come</li></ul>So that the back of the jukebox looks nice too, I redesigned the plate of the back and cut it out with a laser cutter.The next step was to install two new speakers in the jukebox housing, so that you can use the jukebox &#34;standalone.&#34; With a switch you can choose between the intern or extern speakers.The last step was to add a mode, where the LEDs react to the music. So I added a <a href="https://www.dfrobot.com/search-dfr0126.html">https://www.dfrobot.com/search-dfr0126.html</a> module from DFRobot. This module can analyze the sound and sends the information to an Arduino.
