Do you need a way to quickly and easily set a timer for short intervals? This audio and visual timer has you covered! All you need to do to set your timer is turn the potentiometer knob and push the button. One LED = 5 seconds Two LEDs = 10 seconds Three LEDs = 20

People love listening to music. It is as they say, music reflects our mood. And it is a spectacle to see music become ‘alive’ right before our eyes. Well, that’s what music visualization does. According to Wikipedia, music visualization “generates animated imagery based on a piece of music. The imagery is generated and rendered in

This is add-on of the audio amplifier project result which is introduced in other instructable. (https://www.instructables.com/PC-Speaker-Amplifier/) Usually many types of sound level meters are directly connected with input (or rarely output) signal lines of amplifier. But personally I’m thinking any electrical connections with amplifier circuit may surely degrade music playback quality by inserting some noises

Reaction time is a measure of time a person takes to identify a stimulus and produce a response. For example an athlete’s audio reaction time is time elapsed between firing of gun shot (that starts the race) and him or her starting the race. Reaction time plays an important role in situations of immediate response

Welcome to my Instructables on how to build a RGB LED backlight for e.g. the back of your TV or desk. The Schematic itself is very simple since the WS2812 LED Strips are very easy to interface with e.g an Arduino Nano. Note: that you do not have to use the additional MSGEQ7 Audio Analyzer circuit if you only want the

This instrument was build by Lieven Menschaert and Danny Leen using an Arduino Uno and some hardware components ( rotary encoder, potentiometer and simple iron bolts). The software running the actual audio and video is a Pure Data / GEM patch. Additionaly Echonest API was used to do the sample cutup. You can send any
In most cases first project in electronics for beginners is building simple audio amplifier. That is because it requires small number of elements and not a lot of knowledge to build one. For low power amplifiers we could use integrated circuits like TDA family. But I will show how to make amplifier using operational amplifier.

Displayed is an audio meter based on Arduino that utilizes a liquid crystal display (LCD). A VU meter, also known as a standard volume indicator (SVI), is a tool that shows the signal level in audio equipment. This project involves displaying the intensity of left and right audio signals as bars on a 16×2 LCD

Hi guys, during the last few weeks, I’ve been working on reconnecting with my love for the guitar. Playing the box guitar was how I relax few years back before the saxophone took over. Going back to the guitar, after 3 years of rarely strumming a chord, I discovered amongst other things that I

The Sound Module-II or the SOMO-II is a small and efficient audio module from 4D Systems that is able to play .mp3 or .wma audio files in the convenience of accessing it within a microSD card or a USB Flash drive (by using external components). The aim of this project is to showcase the basic
