In my previous blog post, I talked about building the pre-amplifier circuit to measure the sound level changes in the environment. However, the real excitement begins with the LED display, which is the next component of my audio visualiser. I have used a NeoPixel ring which consists of 12 colourful LEDs. 

Using an if statement, I was able to control the NeoPixel. For example, if the sound level rises above 600, the code triggers 10 of the NeoPixel LEDs to light up in response. The greater the sound level, the more LEDs light up, providing a dynamic visual display that reacts to the environment in real-time.

With the addition of this new component, my Audio visualiser is complete. From my perspective, an audio visualiser is a must-have component for any music enthusiast. Besides from being a fun build, the visualiser introduced a new dimension to music by creating a personalised visual experience. 

Until next time, I hope you have a great day and stay tuned for more exciting updates on this project!
