Have you ever wanted to know the temperature of your home anywhere in the world? Do you want to add a function to your weather station or monitor the air in your workshop? Let’s take a look at this project! The system consists of a sensor module that measures various environmental variables, which sends its…
In this project we will see how to create an Arduino-based smart lock that can be unlocked from your mobile phone; we will therefore see how to generate a specific QR code, how to create an access page from ESP8266 and finally you will be able to open the door using your phone. We…
Michael Pick created this huge Nintendo Switch as, due to the compactness, the original is easy to lose. He created a fully functional console starting from a TV and a Nintendo switch by combining them with wooden and 3D printed parts. Inside there is an Arduino Uno that reads the pressure of the giant 3D…
If you often happen to make solenoids, tesla coils, inductors, electromagnets or coils in general, you may want to consider building this project or just take inspiration to make bigger ones. The system is composed of several PVC pipes that form the structure, an Arduino Uno, two NEMA17 stepper motors controlled by the special shield…
As we know, Arduino Uno includes a 10-bit ADC (analog-to-digital converter) inside its ATmega328p, which takes a signal between 0 and 5V and produces a digital value that varies from 0 to 1023. However, attempting to measure any voltage above 5V will cause some less than desirable results, such as creating magic smoke and destroying…
This project was inspired by the vision of a real boat equipped with various sensors capable of measuring the depth of the seabed; we therefore thought of building an autonomous small-scale boat to perform the same tasks. This could be equipped with the necessary sensors and programmed to guide you along a desired path and…
Arduino-powered quadrupedal robots are fairly common designs for hobbyists to build once they’ve gotten a little more comfortable with embedded systems. A problem with many of the pre-designed quad platforms is that they take a long time to assemble due to their large size. This is what inspired Technovation to create their own quadrupedal micro…
With 10 million Arduino UNO sold worldwide, this board becomes the most widespread prototyping board ever. The first Arduino UNO board was introduced in 2005 and in those days integrating a communication system such as WiFi was extremely expensive. So why not think of something that would allow all owners of this board to make an…
In this project we will see how to make an anemometer (instrument for measuring wind speed and direction) using an Arduino Uno R3, two VL6180X laser distance modules and a section of tube made of plastic or similar materials. We will also use Processing3 to display wind speed and direction, the latter being independent of…
Relationships and mathematical patterns are all around us, in our daily life as well as in nature. These patterns can range from simple to complex, from harmonious to chaotic. Regardless of the type of pattern, these geometric figures intrigued us so much that we decided to investigate the underlying mathematics. In the following project we…
There are several ways to solder PCBs with SMD components. We have seen the oven, but there are also plates in which to place our board on top and wait for the solder paste to melt in order to solder the components on the PCB. In this project we will see how to build one…
Control any MIDI parameter value of your DAW through hand movements. The first controller was made using the knobs of a potentiometer, however the functionality of the knob is only to send values from 0-127 and this can be done by any means, so we thought of using the ultrasonic sensor. This design has been…
