This one’s for you! If you want to see another take on a Bluetooth speaker with a Neopixel display, check project here. All the chaos is hidden away, underneath a well-built wooden case. That may be why the wiring looks a bit scary. didn’t realize how many wires would be flying around inside the speaker. Reddit isn’t exactly a great code repository, so please, setup a GitHub account, and/or drop your project on Hackaday.io! If you’re curious about the code for this project, posted it on his Reddit thread. When the stereo is off, a DS3231 real-time clock module allows the Arduino to display the time on the two rings. When music is playing, MSGEQ7 allows the Arduino to play a light show in time to the beat. While hasn’t run any longevity tests on his setup, we’re guesstimating it would be rated in days.Įvery Bluetooth speaker needs a sweet light show, right? wrapped his 2″ full range speakers in Neopixel rings from Adafriut. himself said that is absolute overkill for this project. Power comes from a portable laptop battery rated at 185 Wh. The amp is a 15 watt, 12 volt model based on the popular TDA7297 chip.
Instead, he’s created a sound-reactive Bluetooth speaker that may not earn him an A grade but will at least keep the team entertained. Should be working on his senior design project.
