In the era of Internet of Things, we wanted most of our home appliances to become smart. But currently, smart devices may cost much more than their offline counterparts and they often do not communicate with each other. Trying to overcome these limitations, A Ph.D student invented a way to turn entire rooms into smart

It is a common situation in electronics to have a control loop, that is some sort of feedback that drives the input to a system such as a motor or a heater based upon a sensor to measure something like position or temperature. You’ll have a set point — whatever you want the sensor to

Introduction Sometimes, it is necessary to add a temperature indicator into your projects. Therefore, in this tutorial you will learn how to hack your analog Voltmeter and convert into an analog Thermometer using Arduino and a DS18B20 temperature sensor. DS18B20 Module In the first place, the Maxim DS18B20 digital thermometer provides 9-bit to 12-bit Celsius

The drone industry is booming, and the technology is just… cool, to put it plainly. Flying robots, many of which are completely autonomous delivering our goods and also spying on us. Makers and hobbyist are getting on the bandwagon, making their customized drones with available parts. With the boom of UAV (Unmanned Autonomous Vehicle) and
I worked on creating a Internet connected worked on creating a Internet connected last week using my open source WiFi relay project as platform. We observe quite dry air at our house, I suspect this is due to the fact that we use fan coils for heating/cooling. Humidity levels at home are usually below the 30% mark, which poses a health

If poetry is your thing, this hack might convince you that your brain is more advanced than the rest of us poor sots. [Roni Brandini] designed a system that prints lines of poetry when you concentrate. The Mind Poetry project uses an EEG headset from Mattel’s Mindflex toy and pipes your brain’s signals to an Arduino

In my previous article, I have made the Bridge Monitoring System using Wireless Sensor Network project, which allows me to display all the related measurements from Arduino on my PC. Therefore, in this article, I am going to explain in details on how to display the Arduino measurements using Laboratory Virtual Instrument Engineering Workbench (LabVIEW). Two analog

Now that digital imaging sensors are starting to become more freely available to the masses, all kinds of open source projects have been popping up that use them. Most of them are typically fairly limited to things like the Raspberry Pi or development boards like the Arduino and ESP32. But now, there is a new and pretty serious looking open
