Linear Bench Power Supply

DETAILED DESCRIPTION This project is a simple linear bench power supply with adjustable voltage and current. It is meant to be a learning experience, putting ideas of circuit design, feedback, stability into practice building a complete practical power supply. I have intentionally avoided using a 3 terminal regulator or purpose built chip and instead implemented the feedback for voltage and current using a ...

Capacitance Meter using Arduino

When we come across circuit boards which are previously designed or we take out one from old TV or computer, in attempt to repair it. And sometimes we need to know the capacitance of particular capacitor in the board to eliminate the fault. Then we face a problem in getting the exact value of capacitor from the board especially if it is a Surface Mount Device. We can buy equipment for measuring the capacita ...

Controlling RGB LED using Arduino and Wi-Fi

In last tutorial, we explained controlling a Robot using Wi-Fi and Arduino, and in this article we are with our next IOT Based Project- RGB LED Flasher using Wi-Fi. Here we have used Arduino and ESP8266 Wi-Fi Module to control the colors of RGB LED, through a Android Phone, over the Wi-Fi. In this RGB Flasher LED, we have used an Android Mobile App named “Blynk”. Blynk is a very compatible app with Arduino, ...

0-24v 3A Variable Power Supply using LM338

Batteries are generally used to power up the Electronic Circuit and Projects, as they are easily available and can be connected easily. But they drained off quickly and then we need new batteries, also these batteries cannot provide high current to drive a powerful motor. So to solve these problems, today we are designing our own Variable Power Supply which will provide Regulated DC voltage ranging from 0 t ...

DIY Speedometer using Arduino and Processing Android App

In this project we make a Cool Speedometer for bikes or any automotives by using Arduino which broadcast the speed using Bluetooth to an Android application that we created using Processing. The complete project is powered by an 18650 Lithium cell and hence highly portable along with your vehicle. To spice it up a bit more I have added the option of charging your mobile phone as it displays your speed. Yes, ...

Arduino Data Logger (Log Temperature, Humidity, Time on SD Card and Computer)

As Engineers/Developers we always rely upon the data collected to design or improve a system. Recording data and analyzing them is a common practice in most of the industries, here we are building Arduino Data Logger Project where we will learn how we can log data at a specific interval of time. We will use an Arduino board to read some data (here temperature, humidity, date and time) and save them on a SD ...

Simple Arduino Digital Voltmeter

With a simple knowledge of Arduino and Voltage Divider Circuit, we can turn the Arduino into Digital Voltmeter and can measure the input voltage using Arduino and a 16x2 LCD display. Arduino has several analog input pins that connect to an Analog-to-Digital converter (ADC) inside the Arduino. The Arduino ADC is a ten-bit converter, means that the output value will range from 0 to 1023. We will obtain this v ...

Geiger–Müller counter that works with Arduino

The Geiger–Müller counter is a relatively simple tool to measure ionizing radiation. To increase sensitivity, construction presented here contains three (instead of one as usually) soviet STS-5 lamps. This is important for measurements of natural sources of (low) radiation like soil, rocks (an article about my trip with Geiger–Müller counter on Śnieżka mountain). Principle of operation of a Geiger–Müller co ...

Interfacing Hall Effect Sensor with Arduino

Sensors have always been a vital component in any Project. These are the ones which convert the real real-time environmental data into digital/variable data so that it can be processed by electronics. There are many different types of sensors available in the market and you can select one based on your requirements. In this project we will learn how to use a Hall sensor a.k.a Hall effect sensor with Arduino ...

Blinky on Arduino Zero

Run a powerful open source Operating System on Arduino Zero to blink an LED on the board and open up a whole world of control capabilities! Story Version: Version: 0.9.0 (latest) We decided to write an open-source, hardware-agnostic OS for commercial IoT devices that provided low level configuration options to deal with power, memory, and performance constraints across various types of micro-controllers and ...

Measuring Seismic Activity Using ProtoCentral OpenPressure

Seismic activity or "Vibrations of the earth" is measured using ProtoCentral's OpenPressure 24-bit DAQ System. Introduction A geophone is a magnetic device used to measure the Earth's normal vibrations (some abnormal during events such as earthquakes). These movements are also present when there is a small explosion (commonly used for mining and exploration purposes). The principle of a geophone is similar ...

A Simple Arduino LED Example in Proteus

Hello friends, I hope all are fine and having fun with your projects. Today, I am going to share a very Simple Arduino LED Example in Proteus ISIS. I have designed a very basic example in Proteus in which I am going to blink single LED first using Arduino and then I am going to blink multiple LEDs in Proteus. When you start working on Arduino then Arduino LED example is the first example which you must try ...
