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...

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...

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...

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...

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...

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...

The idea of this project is to show the high and low tide times predicted for the day and a graph with the trend in the last 24 hours. In addition to this we also find basic...

The project attempts to recognize different bird calls by continuously listening to audio through the Nano 33 BLE Sense’s built-in microphone. The call of the bird heard will be analyzed and classified; if it is not heard,...

The Maslow is a large format CNC router capable of cutting wood and other materials with precision and repeatability, based on a digital file. A CNC (computer numerical control) machine allows manufacturers to automate the cutting process...

The aim of this project is to create a device that uses Artificial Intelligence to detect the faces of those who want to have breakfast and pour the cereals they have previously chosen. On a practical level,...

The recognition of vehicle number plates is a process as complex as it is necessary, used for example at motorway toll booths or to identify who violate traffic rules. Here we propose a Raspberry Pi-based system that...

In this project we will see how to build a pair of glasses in which the circuits for Bluetooth headsets are inserted in the frame. Therefore you can listen to music wirelessly while wearing. The circuit consists...

In this project we see how to build a particular musical instrument called AirBass. It’s a sensor-based real electric bass emulation that allows the user to play distinct notes while not pressing strings. On a more specific...

In this article we will see how to build a fire and gas detection system that also provides protection. We use Arduino Nano as a microcontroller and two sensors: MQ-2 gas sensor and the flame sensor. We...

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...

With this system, you no longer have to worry about your plant running out of water. Using a humidity level sensor, its water level will be monitored every 30 minutes and, if necessary, an extra spray will...

In this project we see how to build an Arduino-based capacitive kitchen timer that allows users to interact via touch input. The finished device is driven by ATMega328PU (the same microcontroller on which Arduino UNO is based)....

In this project we see how to make a walkie-talkie using an ESP32; audio data is transmitted via UDP or ESP-NOW transmission. So the Walkie-Talkie will work even without a WiFi network! The system is based on...
