If you also want to make only gorgeous music led lights how to make music led lighting : main need for the following steps.
1.selection of LED and controller
need to buy RGB LED strip lights or beads, and LED controller with audio input. The controller generally has a built-in audio decoder chip, you can convert the audio signal into LED color control signal.
Audio decoding LED controller: this is the key control element. It is built to analyze the audio signal decoding chip, by analyzing the low frequency rhythm part of the audio, to generate control LED red, green and blue PWM signal, to achieve the LED color to follow the music change.
Common LED controller optional models such as.
– WS2812B controller: an open source controller, you need to write your own code to analyze the audio and control the LED. more complex, suitable for people with a certain programming base.
– UCS1903 controller: a simple and easy to use controller, built-in audio decoding program, through the microphone to get audio input can directly drive the LED changes. Simple operation, suitable for ordinary users without programming foundation.
– K1000C Sound Activated Controller: a dedicated music LED controller, built-in advanced audio decoding chip, through the microphone to obtain audio can produce complex LED change effect. The price is medium, the use is also relatively simple, the performance is better.
In addition, there are some App or voice control of the LED controller, through the cell phone App or voice commands to select the LED change mode and color. The use of more simple and intelligent, but the price will be more expensive.
For different users and needs, different types of LED controllers can be selected to achieve musical LED lights. RGB LEDs as the basic material, the selection of the controller determines the complexity and intelligence of its function.
2. Select the audio input interface
the controller supports audio input common microphone, 3.5mm audio jack and RCA interface. According to the audio source to choose the corresponding interface, for example, computers can choose 3.5mm jack, DJ equipment can RCA interface.
3 welding LED and controller:
according to the LED light bar connector instructions, welding LED power, ground and data lines to the corresponding interface of the controller. Usually red power, black ground, other colors for the data line. Welding according to the polarity of the corresponding, otherwise the LED can not be lit.
4. Connect the audio source:
the selected audio interface is connected to the output terminal of the audio source device. Turn on or turn up the volume of the audio output device, so that the controller can receive a strong audio signal.
5. debugging and testing:
LED will first light up after power on, and then when the music is played through the selected audio source, the LED will follow the rhythm of the music to change color. If the LED does not change, you need to check the connection and welding lines, or turn up the volume.
Wire connection: Check whether the audio input interface (microphone or audio jack) is correctly connected to the input of the controller. And check whether the LED’s power red wire, ground wire and RGB tri-color data wire are correctly connected to the corresponding output interface of the controller. If there is a problem with the connection, the LED is not working.
Welding quality: If it is connected by welding, check whether there is an obvious short circuit or open circuit in the welding joints. Microphones and LEDs are usually low current, poor welding quality can easily affect its normal work. If necessary, re-welding.
volume size: if the line connections are correct, you need to check whether the audio signal input to the controller volume is large enough. If the volume is too small, the controller can not resolve the obvious low-frequency rhythm, the LED will not have the effect of dynamic changes. At this point, you need to adjust the volume of the music playback device.
Controller settings: Some LED controllers require some basic settings to enable the music mode, such as selecting the microphone as an input or enabling the controller’s audio decoding function. Check the controller’s documentation to confirm that there are no such settings options are not completed.
Code errors: If you are using a hardware platform such as Arduino to parse audio and control LEDs, you need to check the logic of the code written for errors. Code errors can also lead to LEDs can not change correctly.
6 assembly into products:
the LED, controller and line assembly in a suitable housing, and in the housing assembly audio input interface, you can make a complete music LED decorative lights.
It should be noted that such products require a certain degree of electronic knowledge, if not at all, you may need to find the help of other enthusiasts. In addition, choose a programmable LED controller will be more flexible, you can design their own LED change mode. However, it is also more complex and requires some programming skills.
In short, by purchasing RGB LEDs and audio decoding controller, soldering the two together and connecting the audio source, you can easily achieve a simple music LED decorative light!
The following points need to be noted about led music programming
1. Purchase LEDs and controllers:
You need to purchase RGB LED strips or bulbs and LED controllers with audio input. The controllers typically have built-in audio decoding chips to convert audio signals into LED color control signals.
2. Debugging and testing:
After powering on, the LED will light up first. When playing music through the selected audio source, the LED will change color with the beat. If the LED does not change, check the connections and soldered circuits or increase the volume.
3. Connect the audio source:
Connect the selected audio interface to the output terminal of the audio source device. Turn on or increase the volume of the audio output device to allow the controller to receive a stronger audio signal.
4. Code error:
If a hardware platform like Arduino is used to parse audio and control LEDs, check if there are any logic errors in the written code. Code errors can also cause the LED to not change properly.
In the debugging process, the stable and clear audio input signal is the premise for the music LED light to function properly. This is very critical.
If Arduino code is written to implement music LED control, code errors can also be a possible reason why the LED does not work properly or the effect is not ideal.
Solving code errors can be:
1. Review all code according to programming logic to confirm obvious errors.
2. Debug each line of code in the Arduino IDE to check if the values and signal waveforms are correct.
3. Check the debug information received by the Arduino serial monitor to determine if the program has errors or exceptions.
4. Compare with the code of other successful cases to find deficiencies in your own code.
5. If you still can’t solve it, you can ask questions in the developer community. Experts should be able to help find the problem.
