Volt-Amp meter using AVR microcontroller

Voltage and current are two most important parameters of electricity. This project teaches you to build a simple volt-amp meter using avr microcontroller. This project may not enable you to build a high end measurement tool but will be a good diy project which gives a better understanding on A/D converter in microcontrollers. This meter is capable of measuring voltage ranging from 0 to 30V and current rangi ...

Irradiance/Illuminance Meter using TLR235R sensor with AVR Atmega

The TSL235 is a light-to-frequency converter. This library reads TSL235 output frequency and convert it to irradiance, and then to illuminance. Irradiance is the power of electromagnetic radiation per unit area (radiative flux) incident on a surface. It's expressed in watt per square metre, the symbol is Ee. In photometry, illuminance is the total luminous flux incident on a surface, per unit area. It is a ...

0-25V Digital Voltmeter using AVR Microcontroller

In this project we are going to design a 25V range digital voltmeter by using ATMEGA32A microcontroller. In ATMEGA, we are going to use 10bit ADC (Analog to Digital Converter) to build a digital voltmeter. Now the ADC in ATMEGA can not take a input more than +5V, so for getting a higher range we are going to use a voltage divider circuit. [caption id="attachment_34889" align="aligncenter" width="600"] Digit ...

Atmega Alarmclock & Thermohumidity meter

First, let me introduce you my project. I made an Alarm clock with extended functionality & thermometer and humiditymeter. Everything started when my friend (who used to bring me some old electronic rubbish and I used to check if there's not something useful) brought me some cashing register display similar like that. When I first see them I knew that I will made from it alarm clock. I'm programmer and ...

DIY: Retro Style Analog Volt Meter using Servo Motor

Digital equipments have rapidly replaced Analog equipments in the long run. Well that is because the former has lot of advantages over the latter. But do you miss those retro style analog measuring instruments? Those pointy indicators and graduated scales? Well I do and so have decided to build one with the “modern” parts. This article will show you how to make a Retro Style D.C. Voltmeter which can measure ...

Light Tracker Demonstration

Electricity is the most required and important element of human life. We cannot imagine our day to day life without electricity. Electricity is generated using conventional (coal, diesel) and non conventional (water, wind, sunlight) energy sources. The recent and latest trend is to generate electricity from solar energy. The solar panel (made up of solar-photovoltaic cells) converts solar energy in to elect ...
