Preface There’s nothing nefarious here, nor is the information contained herein particularly helpful to thieves or the dishonest. A thief would just cut the dang thing open and be done with it. The story So I bought a fire safe to protect some documents that I wanted protected in the unlikely event of a house […]

Reading Hack a Day I found an interesting challenge: drawing their logo somewhere. And the fact that was even more interesting: “preference will be given to the largest and smallest submissions“. I started figuring out how to do something like that with the things I had around, and settled for using a laser and two servos. Even though

This product allows you to set separate turn-on and turn-off times and those repeat every day. The disadvantage of this product is that, as the seasons change, you need to constantly adjust the turn-on and turn-off times. As illustrated in Figure 1, the variation over the year (in sunset time in this example) is very

About this project This is a very simple and easy-to-build project that provides a sensor on the pedal crank of any exercise bike and generates keyboard output triggering Google Maps Street View to advance via the up arrow key. In my design, you pedal the crank five times, and then the Street View receives an up-arrow command

While LPG is an essential need of every household, its leakage could lead to a disaster. To alert on LPG leakage and prevent any mishappening there are various products to detect the leakage. Here we have developed an Arduino based LPG gas detector alarm. If gas leakage occurs, this system detects it and makes an alert

Humidity and Temperature are very common parameters for measuring at many places like farm, green house, medical, industries home and offices. We have already covered Humidity and Temperature Measurement using Arduino and displayed the data on LCD. In this IoT project we are going to Monitor Humidity and Temperature over the internet using ThingSpeak where we will show
Live Temperature and Humidity Monitoring over Internet using Arduino and ThingSpeak Continue Reading
Thermometers are useful apparatus being used since long time for temperature measurement. In this project we have made an Arduino based digital thermometer to display the current ambient temperature and temperature changes on a LCD unit in real time . It can be deployed in houses, offices, industries etc. to measure the temperature. This project is based on Arduino

Raspberry Pi and Arduino are the two most popular open source boards in Electronics Community. They are not only popular among Electronics Engineers but also among school students and hobbyists, because of their Easiness and Simplicity. Even some people just started liking Electronics because of Raspberry Pi and Arduino. These boards have great powers, and one

Today, we are going to Interface 2.4 inch TFT LCD Shield with Arduino. By using this color TFT LCD shield we can show characters, strings, blocks, images etc on the color TFT LCD. And we can use this TFT Shield in many applications like: Security System, Home Automation, Games etc. Interfacing TFT LCD with Arduino

Wireless communication between Electronic devices and modules is very important, to make them ‘Fit’ in the World of Internet of Things. HTTP protocol and HTML language have made it possible to transfer the Data anywhere in the world, over the web. We have already covered some projects which use Wi-Fi with Arduino, have a look
