Music reactive led circuit diagram

I personally hear a lot of music. This is my secret for my energy. Even I am listening to music while writing posts for you guys. Low-frequency audio signals came from Audible devices. This signal is too low to hear with a Speaker. Here one transistor is used so it means it can only give the mono output. Suppose we are talking about the left signal. But the channel wire is different for different channels.

Now the Transistor Switches On and off for the consequent frequencies. For this, the small signals will be amplified. And the bandwidth will also be high. Now We can hear the loud sound from the speaker. Here are Some Pictures for making the Circuit.

You can also make the circuit in the Breadboard. So, there will not be any loose connection. This is a simple Circuit. So there are some disadvantages to the circuit. There is no noise cancellation in the circuit. So, you will find extra humming noise in the amplifier. There is too much loss in the circuit. This is not power efficient.

Anyway keep up the nice quality writing, it is rare to peer a nice blog like this one today. Can I just say what a comfort to uncover a person that truly understands what they are discussing on the internet.I'd been thinking about having a go at making lights that would change colour in time with some music, to add to a jukebox, for a while and when I saw the LED Strip speed challenge, and since we're in lockdown at the moment, I thought this would be the ideal time to try it out.

First I'd like to point out that this can be used with any music source, it is not connected to the jukebox in any way as I would not want to make any modifications to it which would take away it's originality. This project uses an ordinary RGB LED strip along with an arduino I used a nano but you can use an uno or mega if you like and an arduino sound detection module. I have taken information, pieces of code and circuit layout from other peoples previous instructables and added to these and combined them together to create this project, which lights a different colour of led depending on the pitch of the sound being picked up.

My first attempt at this was a bit simpler and displayed a different colour depending on the volume of the sound being picked up but the effect was not really what I wanted so this version that detects the frequency of the sound gives a much better result. I used some code from the Arduino Frequency Detection instructable and some code and circuit layout from user C. Arduino nano or uno or mega 12V LED RGB Strip Sound detection module for arduino the one I had came along with a starter kit I bought a few years ago and is slightly different to the one in the link but it should work just the same 3 x 2N transistors 3 x rectifiying diodes 1 x ohm resistor.

You will also need 2 power sources, I powered the arduino from a usb charger for a phone and I used a 7. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. Build the circuit as shown in the fritzing diagram.

The diagram shouldn't be too hard to follow. I've used pins D9, D10 and D11for the outputs to each transistor, and the A0 pin for the analogue input from the microphone module. I made this on a breadboard to begin with and once I was happy with the result, soldered all the components onto a double sided strip board as seen in the second image.

Upload this sketch to your arduino. You can play around with the frequency values in lines 96, and and adjust the delay values on lines 98,and to have the lights respond to different sound frequencies and to stay on for longer if you want but I'm quite happy with the results from this with these values. Connect the two power supplies to the set up 9v for LEDs and a USB supply for the arduino and you should now have a music reactive led strip.

You may need to adjust the potentiometer on the sound module so that the leds don't stay on all the time or off all the time. You can set these near any music source something with a strong beat will give a better effect and they pulse and change colour with the music.

I sat mine inside a jukebox and fed the power supply wires out through the back door to hide them from viewwhile the self adhesive led strip is stuck onto the diffuser that normally let out a plain white light from a fluorescent light.

Add Teacher Note. Attachments sound-led-frequency. Did you make this project? Share it with us! I Made It!It's pretty cool to have at parties and also works well for action movies, if using the low pass RC filter. I built this circuit to react to the low frequency tones of the music vs. As you can see in my diagram, this portion is just a simple RC circuit. You can adjust the resistor and capacitor values as you see fit.

The RC circuit filter allows for only the passing of low frequencies. If you want to pass high frequencies only, I would suggest using an RL circuit. I use a simple 1-stage filter, as it gives me the desired results. Here I use two uF capacitors in series to give an equivalent capacitance of uF with a ohm resistor.

The cutoff frequency here would be 10 Hz. I connected the input using one of the 3. You may be able to just tie it directly to the 12V source, but I like to use the good ole' 5V for IC chips. This also isolates from the erratic current spikes from the LED strip turning on. The formula is as follows:.

Here if you want to include a gain adjuster for different sources, I would change R2 for the kohm potentiometer. Note: Since the audio source will probably have an audio adjuster that can be considered a pre-amp, it can also be used as a primitive gain adjuster, negating the need for the potentiometer, hence why it's listed as optional.

The 12V power source amperage should be sized so that its amperage can sufficiently turn on all LEDs connected.

See picture. Also worth mentioning is that the volume of the sound system playing the music will not affect the sensitivity of the LEDs, but the volume of the sound source will.

This is a project that i follow based on the youtuber's "Natural Nerd" that they done. This is my version of the project. All credit goes to them and a big shout out to them for provide me the detail on how to do the project. Youtube link. First things first: what kind of supplies do we need and what do they cost?

Well, they are largely optional, and can be made with much improvisation. Even so, some key items are needed if you want to follow this guide:. Depending on the look you want, you might want to arrange the strips differently or diffuse the light in another way. This is where you can be creative. If you like my approach, I used the following items:. All things considered I spent around RM The powering the component will be a straight forward method.

If you using the external power supply such as AC to DC power source, you will be needed a step down module to help you reduce the amount of the current flow to your circuit. Otherwise, if you not using it and you might have a very high chance to burn the Arduino including the components that connected.

The star of the show is the sound detector module. This will provide an analog signal to the Arduino, which we can use to hopefully cleverly light the RGB lights. To be able to do this, we need to power both devices.

Luckily they both require a 5 volt input.

I am using a step down module to step down from 12 volts to 5 volts, but it would be easier to use a 5 volt power source directly. Wire the VIN on the Arduino and on the sound detector board to the positive input. Then wire the GND on the Arduino and the detector to the negative.

Look at the black and the red wires on the attached schematic.
