Hi! Here I present my autonomous music LEDs controller.
Number of LEDs - from 30 to 240
Maximum consumption will be determined by the type and number of LEDs in the tape.
LED strip is not included in the package and is purchased separately based on personal requirements for the number of LEDs and the distance between the LEDs. It is possible to increase the number of LEDs using parallel switching on tapes.
Preparing to connect the LED strip.
Purchase a 5V power supply with enough power to power your LED strip.
If you have only 30 LEDs in the tape, then you can use the USB connection to power the circuit.
If you do not have a connector for connecting the LED strip, you can dismantle it from the end of the strip intended for cascading extensions.
Connect the wires as shown below.
Connect the connector to the corresponding connector on the LED strip.
Connect the LED strip power wires to a 5V power supply.
Use red (+ 5V) and white (GND) LED strip power wires to a 5V power supply or a USB connection if you have only 30 LEDs. When using a USB connection, do not forget to insulate the white and red conductors designed to connect the power source, in order to avoid short circuiting with each other or shorting any of them to the circuit.
Observe the polarity of the power supply.
In the presented figure, the number of LEDs in the tape is 30 and the power is supplied from the USB port of the laptop. White and red LED strip power wires are free. Be careful when turning this on, do not short circuit the power wires between each other or on the circuit conductors in order to avoid short circuit and damage to electronic components.
Download the program to your PC or smartphone and select your favorite program. A quick start guide is provided below.
The color music controller can be controlled from a Windows PC program via a USB connection or via Bluetooth from a smartphone with Android OS. The program for Windows is available for download as an executable file or as source code. For users who, for whatever reason, lack the capabilities of these programs and want to more accurately configure the controller in accordance with their requirements, a utility for Windows is available. The utility is also available as an executable program or as source code.
For the program to work under Windows, you must install the STM32 Virtual COM Port Driver from the site of the microcontroller manufacturer. If you have more than 30 LEDs in the tape, then connect to the USB PC after applying power to the LED strip in order to avoid excessive load on the USB port. After connecting the controller, select the COM port to which the connection is made. You can see it in the Ports (COM and LPT) section by calling the device manager. The figure below in the device manager shows that the controller is connected to the COM5 port.
In the program you can set the number of LEDs in the tape, the number of bands (colors), the source of the audio signal, set the dynamic or music program, the brightness of the tape and the speed of the program. When choosing the number of LEDs in the tape, the number of bands (colors) and the source of the audio signal, save the selected configuration with the corresponding button in the program window. To actually change the source of the audio signal, a reboot of the controller will be required. To do this, remove power from the controller for a while and apply again. The service program has more features. Its description is presented in the documentation section.
Software MUSIC LEDs is available for Android on Google Play.
Wait for connection.
Dynamic program control Music program control
You can set the motion direction or performance mode for programs without directed LED light motion (not present in all programs so far) both for musical and dynamic programs using the third scrolling bar in the Dynamic part of the screen. 3. Creating your own dynamic programs playlist You can create a list of dynamical programs that will be played in rotation. To do this, consistently select dynamic programs, subprograms, directions (modes), and motion speed, adding programs you like to playlist by hitting the ADD button. After you are done, save programs by hitting SAVE. Max. number of programs in the list is 80. Further, you can add programs to playlist at any time by hitting ADD. Do not forget to save your new playlist by hitting SAVE. To start playing your playlist check the box LIST. To clear playlist hold the ADD button for more than 5 sec. 4. Changing color design For simple dynamic programs (from 3 to 29) that change color depending on subprogram (second scroll bar) you can set your own colors. You have probably noticed that the zero subprogram uses red V and yellow V as the first two colors in all programs. You can view all colors used in subprograms from terminal using AT+PC (print color) command.
Have a nice time! The following chapters are not needed for ordinary use, but if you want to customize the controller to your liking, the firmware allows you to do this.
Scheme and files for production are attached. You can assemble this circuit yourself by ordering boards and electronic components. You can also assemble the circuit using cheap ready-made modules, here is the instruction.
