In this Instructable I am going to show how to make a program in Processing that analyzes sound on your computer and sends data to an Arduino that controls an LED matrix to show the spectrum analysis. I will be explaining where to get materials, explaining the coding and wiring needed and providing example programs …
This project involved creating a red, blue, green (RGB) light emitting diode (LED) matrix that displayed the colors of the rainbow. The colors of the rainbow were chosen to show the full color spectrum that the LEDs are capable of, while still giving distinct variation within the LED matrix. Read more: RGB LED Grid
Continuing with ATtiny85, today I’d like to share how to build a music spectrum analyzer on 16×20 RGB led matrix. The music signal FFT transformation and LED Bit Angle Modulation are all carried out by one DigiSpark ATtiny85. Please watch my video below: Step 1: Things We Need Main components are as follows: 1 x DigiSpark ATtiny85. …

In this project we’ll create a small add-on PCB containing the a MSGEQ7 spectrum analyzer circuit and show how it can drive the RGB LED cube kit from Freetronics. This allows the cube to display the seven bands over four horizontal planes. There is a small amount of assumed knowledge for this project – To save repeating …
