![]() Since this was part of my weekend electronic project I didn’t feel to add any closed frames to this circuitĪlso we are not dealing with any harmful electronic components which poses any sort of electrical risk to user. If u have a 3D printer amazing frames can be printed for smooth finish. Watch the Led strip reacting to every single beat of your music! You can use this in your house party as well and surprise your friendsĪny plans to make this for your school project you may need to add closed frame made using cardboard/plastic Play your favorite music I recommend to use rock and pop music, Bass in those songs will be pretty highī ring the sound sensor close to the speaker of your mobile or computer or music box Note: If you are using larger number of LED in the Strip don’t use board to power those LED strip as the LED draws too much power/current and cause serious damage to board all this happens on long term usage I’m using power bank to power this project if you are using external power supply u can connect to NANO board pins ![]() Once the program gets uploaded project is ready for use Upload the code by clicking on upload button( image number 8) If you need any changes in color to be displayed you can alter color and timings in the code ![]() Open ARDUINO IDE Software on your computer(image 7)īefore uploading code check for COM port number Using USB a type USB cable connect Nano board to your computer (image 5 and 6) steps to upload code Uploading Arduino Code If we use separate source for sound sensor we need three different power sources one for Arduino, one for STRIP other for sensor so it becomes quite complex to manage such circuits, so I recommend not to use 3 separate sources. In this project you can connect LED strip to separate power source while connecting only signal pin to Nano board, but sound sensor should be connected to Nano board only If you are using larger number of LED in Strip u may need capacitor and resistor of specific ratings and separate power source for LED strip(as it consumes too much power) which harms Nano. Note: If you are making project like this(I did with 60 LED’s) you don’t need extra circuits for safety Red and white are for positive and negative power supply, whereas green is signal input terminal for ARGB led strip Sensitivity can be adjusted by turning screw on sound board Now let’s make circuit connections to WS2812B LED stripĪRGB led strip has 3 wires in my case wire colors are red, white and green Let’s begin with sound sensor circuit first Means each led in strip can be control individually producing any light color using RGB combination, Also called as WS2812B LED StripĬoming to circuitary part, I included circuit diagram so that everything is clear and easy to understand if you are planning to make this.ĬODE for Music Reactive LED Light using ArduinoĬircuit Diagram for Music reactive lights Steps to make circuit, Normal LED strip light won’t work for music reactive led light as there is no option for signal input, here I have used ARGB led light strip which stands for addressable red green blue. There are lots of other sound sensors available outside which responds to even very low sound(sparkfun sound sensor) but the price of those sensors are quite high that is around 12 dollars.
