The objective of this tutorial is to learn how to use the DHT22 sensor with Arduino uno. The room temperature and humidity will be printed to serial monitor and also will be displayed to the LCD 4×20 in Proteus ISIS. DHT22 is simple basic, cheap digital temperature and humidity sensor. It uses a capacitive humidity […]

Here we have a good example of how a requirement for a simple tool spirals out of control and spawns a project that takes months to complete and ends up dwarfing the project that it was originally expected to facilitate. You see, some time ago I was fiddling around with a project, something to do

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

Step 1: Introduction In this Instructable I am going to attempt to show you how to put together a little project to use the Blynk app (optainable at http://www.blynk.cc/) to display the temperature remotely on a iOS or Android device. I came across an posting on my Google+ where somebody required some help with this.

An AC (Air Conditioner) which was once considered to be a luxury item and was only to be found in big hotels, movie halls, restaurants etc… But, now almost everyone has a AC in our home to beat out the summer/winter and those who have it, worry about one common thing. That is their high

Quantifying cooling A few months ago +Neil Darlow mentioned that he had replaced his Mendel90 fan with a quiet version and it seemed to give better cooling results. This made me curious because quieter fans of the same dimensions generally spin slower and produce less airflow. So I purchased one to compare but then realised

Dresden, Germany – 8 February 2016 – Heliatek R&D teams reached a record conversion efficiency of 13.2% for an OPV multi-junction cell, setting a new world record for the direct conversion of sunlight into electricity using organic photovoltaic cells. The measurement was independently confirmed by Fraunhofer CSP. Thanks to the excellent low light and high

Today I am going to show you how to make An OpenSource Arduino UNO OLED Clock That Also Measures Temperature. This project is an OpenSource and it’s open to everyone. It doesn’t require any special engineer skills, and will take you less than couple of hours once you have all the parts you need. This
OpenSource Arduino OLED Clock with temperature measurement Continue Reading
A friend has approached me regarding his solar project. He wants to install a solar panel together with a battery and an inverter in order to have power at his allotment garden. He had looked at a hobbyist project where an arduino was used to build a MPPT (maximum point of power tracking) charge controller.
