In this project, we will go over how to build a vibration detector circuit.This is a circuit which can detect and measure flex, touch, vibration, and shock.The sensor we will use to detect these movements is a piezo vibration sensor from Measuremenet Specialists (MEAS). The sensors are a thin strip of piezoelectric material with a […]

Motivation I was building some Lo-Fi CMOS synthies, just like the ones you see here: http://hackaday.com/2015/02/04/logic-noise-sweet-sweet-oscillator-sounds/ or here: http://www.nicolascollins.com/hackingtutorial11.htm Soon after I played around with some simple sequencers and multiplexers to generate more complex sound patterns. I thought it would be cool to have a device to gate oscillators or switch multiplexers with a random […]

This tutorial will describe a way of controlling an iPod remote, and thus, an easy way of getting some music and sound out of your Arduino project. The remote we used was an unofficial remote I found on the worldwide auction site for around 10 USD, an opto-isolator can be found in your local electronics […]

This is a project based on Arduino board which can measure the unknown resistance values and perform diode test and continuity testing. When we connect the unknown resistor on the breadboard circuit, the 16×2 LCD displays the resistor value and when we connect a diode the LCD displays the type of diode if it is […]

Build an Arduino-powered version of the “Four Letter Word Generator” (FLW). This version generates “words” on the fly – it does not use a list. The “original” version from the 1970’s used B7971 nixie alphanumeric tubes. These tubes are getting hard to find and they’re certainly expensive. They also require interfacing with high voltage and […]

Hey everyone, back with another project. The antiAFK is something I originally started working on almost a year ago, but its only been since 2014 started that I’ve been making real progress on all my projects. Plus, I just finished my MSc the other day so now I’ve got all the time to work on […]

The HSM-20G is an analog humidity and temperature sensor that outputs analog voltage respects to relative humidity and temperature. However from this sensor relative humidity is found along with temperature. Relative humidity is the percentage of moistures of airs for a particular temperature [1]. Feature: 1. Storage range: -20°C to 70°C 2. Operating range: 0°C […]

Transistors operating in their avalanche regions are often used to generate fast rise pulses (seeavalanche pulse generator using 2N3904). Many transistors can also avalanche when the connections to collector and emitter are reversed. When operating in reverse avalanche region, these transistors are sometimes referred to as negistors. Because the asymmetry and doping differences between the base-emitter […]

A new method of processing signals via fiber optic cables could vastly increase the distance at which error-free data is transmitted via submarine cables without additional signal amplification. As the technique is capable of correcting corrupted or distorted data being transmitted, it may also assist in increasing the capacity of all optical fiber communications. With […]

This is how to push high resolution real-time data from Arduino-based temperature sensor to your web page without any server-side coding. Arduino is a great device for collecting, storing and transferring data from various sensors but there are times you need to make your data accessible from any place over the internet, like I did […]
