The MSGEQ7 breaks the audio signal coming in into 7 different frequency bands for low, mid and high frequencies. There are two main visualizations I added that I’ll briefly explain the code. This approach should work for other smart home platforms that support RGB lights over MQTT.įollowing up from the previous article, I’ve added a few more visualizations specifically for syncing up the LEDs to the music. Or you can manually control the lights through your smartphone using the Home Assistant user interface. The LED strip can be completely controlled via Home Assistant over MQTT so you can set up automations for changing the light strip automatically.

Thanks to the great MSGEQ7 library on GitHub the software is pretty easy! You can find all my code on GitHub for this project as well. Power Jack to connect power supply to protoboard

Here’s the full hardware I used for reading the audio signal and controlling the LEDs. I’ve talked more about the LED strip hardware setup in last weeks post when creating the WiFi Connected RGB LEDs. The right side of the schematic converts the analog audio signal into the digital signal the microcontroller can understand. The NodeMCU is connected to a logic level converter to communicate with the LED strips at 5V. The left side of the schematic takes care of getting the correct voltages we need (12V and 5V). Check the full schematic below, while it may seem daunting at first it will make more sense the more time you look at it. If you look at the circuit diagram below, the headphone jack is routed into the MSGEQ7 audio analyzer chip that is then connected to the ESP8266 which ultimately controls the WS2811 LEDs. Once you have an analog audio input you can connect it to the headphone jack in the circuit.

Splitter to split the optical audio output on my TV to my speakers and LED stripĬonvert optical audio into analog signal for processing Here’s the hardware I used for splitting the audio and getting it to the NodeMCU: Item One other piece of hardware you’ll need is a headphone jack you can mount to a protoboard for the design. If you’re wanting to use a computer or phone as the music source, you can probably just use a stereo splitter to accomplish the same thing. Therefore, I needed to get an optical out splitter and then convert that signal to an analog signal using a DAC that our circuit can understand. My TV just has a digital optical out for audio which I’m already routing to my soundbar. Audio Splittingįor my implementation, I mounted the LEDs to the back of my TV. One visualization I developed looks at the bass of the song and changes the brightness of the LEDs to match the bass levels, effectively following the beat of the song. Our software reads the levels for each band and creates visualizations. This chip will be responsible for reading an audio signal from a headphone jack and breaking it into seven frequency bands (63Hz, 160Hz, 400Hz, 1kHz, 2.5kHz, 6.25kHz, and 16kHz). To get started, check out last weeks blog post on creating the WiFi Connected RGB LED Strip. From that, we’ll be adding a little sound processing to our circuit. Everything should be hidden well for a high spouse approval factor.The LEDs add a subtle visualization to the music, don’t want my living room becoming a rave.Controllable over WiFi and using Home Assistant.LED strip should still be able to support a solid color and other visualizations.The audio comes in from a headphone jack.Continuing off of my post from last week creating a WiFi Connected RGB LED Strip, I’m adding a new effect: music visualization.
