Using Mozzi Library with 5 potentiometers using arduino

Getting Started The goal of this project was to create filters and controls to that can manipulate sound that is being generated through an Arduino. Normally Arduino can only generate simple tones that are not useful if you are trying to achieve complex sounds and do sound manipulation. In order to do this project Mozzi […]

Arduino Seismic Activity Monitor

Arduino Seismic Activity Monitor – Ethernet Shield

Have you ever wanted to impress your friends by saying something crazy like, “I think there’s going to be an earthquake soon” moments before an earthquake hits? Or do you just want some warning, a few seconds that could save your life. This project will allow you to hook up a seismic sensor to a

Read ASCII String using Arduino

Read ASCII String using Arduino

This sketch uses the Serial.parseInt() function to locate values separated by a non-alphanumeric character. Often people use a comma to indicate different pieces of information (this format is commonly referred to as comma-separated-values), but other characters like a space or a period will work too. The values are parsed into ints and used to determine the color

Power Quality Meter using Arduino

Power Quality Meter ( PQ Monitor) using Arduino

Arduino UNO project, Power Quality Meter, someone would call it’s PQ Monitor or PQ Analyzer. I had already published one  blog  devoted RMS voltage measurements on full band  20 – 20 000 Hz  audio signals. ( Following my own style, I’d refer to already published materials whenever it’s possible ).  This time measurements performed on

Audio VU meter with Extra wide Dynamic Range 69 dB using Arduino schematic

Audio VU meter with Extra wide Dynamic Range 69 dB using Arduino

O’K, after having some fun with stereo version of the VU meter I described in my previous blog-post, now it’s time to do a serious stuff. Studio grade VU meter !!! 24 steps, equally spaced every 3 dB, covering Extra wide Dynamic Range from -63  up to  +6 dB.  Single (mono) channel this time, no messing around,

Arduino gliding altimeter variometer

GoFly – paragliding/hangliding/gliding altimeter-variometer from Your car navigation using Arduino

GoFly is a project based on PNA (car navigation devices with Windows CE), LK8000 tactical fligh computer software and variometer (altimeter) external input based on Arduino board and pressure sensor. Why? -You can build this for about 150$, -Your ordinary PNA (Personal Navigation Assistant) changes to really nice, high end flying computer, with lot of
