Water softeners work using a process called ion exchange in which calcium and magnesium ions from hard water are exchanged with sodium chloride (salt) via a special resin. The water goes into a pressure vessel where it moves through the resin beads, and the calcium and magnesium are replaced by sodium. The resin beads will…
I wanted to please a friend, an environmentally conscious friend who is concerned about mould spores in the air (from damp), additionally he is an occasional smoker and lives on a fairly popular city road, so he’s keen to see what’s present in the air as far as concentration and air quality go. To…
Hello everyone, This is a simple yet great and super easy project. In this project, we are using one ultrasonic sensor to track one object in one dimension, and finding it’s distance. Through this project, we can tell whether the object is going further, or coming closer, or it is at same point- it is…
This project consists of an interface window where we can control up to 8 dimmable lamps and create any effect with them without having to reprogram the Arduino. This can be useful, for example, to create the lighting of a mini disco. It is possible to have a lamp flashing while another is fading…
Phone app to monitor and control vitals of fish in a home aquarium via ESP32. As you saw in the YouTube video, a mobile app connected to the internet has access to monitor and control the aquarium. It can : Feed the fish either manually by specifying the amount of food and click on the…
The idea of this project has been on my mind for a while. The question of what if we can use our environment as a technology canvas motivates me to start experiment with this project. Luckily today we have an amazing device such as Raspberry Pi to use as a brain of the system….
Hello, all! This time, I will teach you how to write programs in the Arduino Web Editor. More info
We develop and test applications with the Pro midi 1284P board. Recently we have introduced and described a new prototyping board called PRO midi 1284, based on an ATmega 1284P microcontroller; after this presentation, made in a previous post, we start to work with it and we explain how to interface it in…
It is halfway between an Arduino Mini (in size) and an Arduino Mega in terms of computational capacity, available memory and integrated peripherals. Since the creation of the Arduino project and the subsequent spread of the original boards, the electronics industry and especially the nascent electronics industry for Makers, has moved in two directions:…
Equipped with an SD card and RTC, it detects and stores temperature, humidity and barometric pressure using a combined sensor, showing the data graphically on a touch display. Nowadays, also and above all in environmental monitoring, we are moving towards connected solutions and more and more integrated into the IoT concept, but not…
Lots of components to make applications that can be programmed with Arduino and assembled like LEGO bricks. How many times did you dream of building something with LEGO bricks when you were a child and see it moving, animated, perhaps integrating a certain amount of programmable electronics to keep up with the times?…
For all electronic designers, having new ideas and sources of inspiration is essential. At the base of the open-source movement there is the sharing of one’s own projects so that other technicians can take inspiration. There are many repositories where you can find complete projects, but now we want to introduce you to our sponsor…
Open-Electronics.org is the brainchild of a world leader in hobby electronics Futura Group srl. Open-Electronics.org is devoted to support development, hacking and playing with electronics: we share exciting open projects and create amazing products!
Open-Electronics.org is not just a container of ideas: it is also a web site lead by a team of engineers and geeks who will take part in the discussions and give support.
Our mission is to become a reference Open Source hacking site with ideas and feedback aimed to enrich the community.
