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. …

Image: Today I am make an Arduino OLED Spectrum Analyzer its work with 0 to 3.3v Analog input. This is very smooth and clear Visualization of audio frequencies. This is very important to make an audio spectrum analyser for DVD Music player, IPod, MP3 player and other Music player not only its look good it …
A group of researchers led by Nick Vamivakas from the University of Rochester has successfully produced particles which have negative mass in an atomically thin semiconductor material. According to the researchers, they have created a device that can generate LASER light using a significantly small amount of energy. All made possible with the help of this so-called negative mass particles. Quantum physicist Nick …
In 1982, the UK’s best selling computer, ZX Spectrum, was released by Sinclair as 8-bit personal home computer highlighting the machine’s color display. And today, a group of makers are introducing the Spectrum Next, an updated and enhanced version of ZX Spectrum. The Spectrum Next is fully compatible with the original one. It enhanced to provide a wealth of …

In addition, with Arduino MAX7219 for code… Electronics Projects, Spectrum Analyzer Circuit Arduino Uno “arduino projects, microcontroller projects, “ the Arduino Uno module held with MAX7219 8×8 LED matrix display module graphic equalizer spectrum …
This article describes a simple spectrum analyser for the 2.4 to 2.5 GHz Wi-Fi band. It’s based on the Cypress CYWM6935 Wireless Radio Module. Although the manufacturer doesn’t recommend it for new commercial projects, it is still widely available from eBay suppliers and Farnell here in the UK. The module has 1 MHz channel spacing …

I’ve been reading a lot about receivers, and it sounds like one important thing is filtering. It makes sense too – simple receivers can suffer from front end overload due to a strong signal. And when on the ham bands, you never know where that strong signal may be – it could be someone driving …
This is an audio spectrum VU meter using the LoL Shield for Arduino . The LoL Shield is a 14 x 9 LED matrix which fits onto the Arduino as a shield and is controlled through an efficient method known as Charlieplexing . It was designed by Jimmie P. Rodgers . This project uses a …

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 …
