It monitors the electricity consumption and sends the detected data to the cloud through the GSM cellular network; it is based on an Arduino Mega equipped with GSM Shield and a board on which the measurement board is mounted. Second and final instalment. In the previous post on Open Electronics, we have proposed…
It monitors electricity consumption and sends the detected data to the cloud through the GSM cellular network; it is based on an Arduino Mega equipped with GSM Shield and an absorption detector board. First instalment. Monitoring the electricity consumption of your home or business is an increasingly topical issue. The electrical measurements made,…
With Arduino Mega, we create, a keyboard with RFID module, a configurable access control system, to manage electric locks. In the market there are different types of controls for electric locks: from the simple insertion of codes to biometric readers, passing through transponder readers (RFID) or magnetic strips. The project that we present…
The project was born with the purpose of helping the deaf community to communicate and interact easily with the surrounding environment. The goal is to convert the basic symbols representing the 26 letters of English alphabet and display them on a smartphone screen. For this system we were inspired by the idea of controlling a…
Can we “listen” a difference between pouring hot and cold water? As you see in the video you can do it, but why? It is mentioned that the change is due to complex fluid dynamics reasons. Beyond the scientific investigation, the question we asked ourselves was: is this ability to “listen to temperatures” something that…
Based on Neopixel and a special ultra-thin Arduino, it simulates the light produced by chimney flames As every year, the approach of the winter season stimulates our imagination and reminds us that electronics can do a lot, not only concretely (creating automatisms for indoor air conditioning) but also for pleasure and leisure; so here are…
The seismometer is a device for detecting earthquakes and measuring their strength. Generally these are very accurate tools and are relatively difficult to build at home. Commercially available sensors are often expensive, and inexpensive shock-sensitive electronic modules are not accurate enough for this purpose. In this project we will see how to create a cheap…
A Solar tracker was created in order to focus solar panels perpendicular to incoming sunlight. This position of the solar panel is optimal for photovoltaic energy generation. The efficiency of the Solar Tracking system vs normal use of solar panels was compared using data collected by my Arduino Power Logger (See details of Power…
This is a simple, autonomous robot with some artificial intelligence. It is designed to explore a maze and when placed back at the entrance, to drive thru to the exit and avoid the dead ends. It is much more complicated than my previous project, which simply drove thru the maze. Here, the robot must…
In this project we see how to make a Bluetooth speaker with a clock. It displays date, time, temperature and humidity and it is updated from Internet at 15 minute intervals. It also has a 32-band audio spectrum analyzer that displays different musical patterns. The clock or spectrum analyzer can be displayed while playing music….
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 this…
In this project we see how to create an I2C system to control motors using a DigiSpark Attiny85 plus an Arduino shield. To test its operation we made a small RC car that uses an M5StickC and connects to the Blynk app to communicate via the I2C protocol. We used two communications in this project…
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.
