Stranger Sounds work with an ardiuno and a DfPlayer Mini Mp3 and a PIR Sensior to display a light show when a person walks up close to it. The PIR Sensior detects the person moving near the device. When motion is detect the ardiuno tells the DfPlayer module to start playing the Strang Things music while playing a light show synced to the tune. When not playing the light show the DfPlayer will play music in the folder denoted /MP3/.
Make sure to have music that will loop while the device is in a stand by in the folder /MP3/ in the SD card. The device will play the song that is in the /1/ folder starting with 001 when motion is detected. The light show is synced with the theme song to Stranger Things.
It is suggested to have a seperate power source for the LED lights than the Arduino; although, if a source has enough current both can be controlled by the single source.
Update the LED Service to allow for providing different pins for data to the LED strip.
