Lately we see many commercial products that allow you to levitate light objects using a magnetic field. There are already assembled kits, but today we will see how to build a more simplified one at home. The project uses an Arduino Nano that controls an electromagnet through a power transistor based on the signal received…
In this project an Arduino Uno was used to build a robot fridge that follows our movements. This uses Bluetooth and GPS communication to understand the path to follow. In particular, it compares its GPS position with that of the phone of the person to be tracked through Bluetooth communication. Arduino communicates with a GPS…
In this project we will see how to build a home automation greenhouse with Arduino Uno that allows you to grow plants even in unfavorable weather conditions. In addition to recreating an optimal environment, a domotic greenhouse allows the automation of fertilizer administration and controlled irrigation. Furthermore, by monitoring environmental factors in real time, you…
In this project we are looking for a solution to control the humidity level in the bathroom. In particular we will try to control an already present fan that is operated manually. You can of course buy a fan with an integrated controller, but this is often expensive and with limited manual settings, here we’ll…
Each inductive load, such as a motor or a transformer, produces an inrush current at startup that increases as the power of the device increases. This is because at start-up only the very low resistance of the windings is seen, before the flux created opposes the passage of current. This current spike could cause the…
The theremin is an electronic musical instrument, the oldest known that does not involve physical contact of the performer with the instrument. In fact, the sound is obtained by waving the hands near its two antennas. Open Theremin is an Open-Source hardware implementation based on Arduino Uno. Together with Arduino, a Shield was built in…
Fed up with shaky footage ruining your video? In this project we will try to address this problem by building an automatic slider for the camera. We create a robust system where the camera slides along a square tube with a pan and tilt mechanism that gives the user the ability to capture any angle….
In this project we will see how to make a 3D printed pet feeder. All modeled parts are available for you to replicate the project in your home. The system is very simple: you are asked to enter two times when you want to distribute food, for example 8:30 and 17:30, then, at the indicated…
After losing the chicken due to wildlife intruders, Elbie decides to create a Smart chicken coop with several functions: Opening and closing the door at sunrise and sunset according to local geographic coordinates; Intrusion detectors with flashing LEDs in two positions; LEDs visible from the outside to show the status of the door; Two buttons…
The goal of this project is to create a complex communication system between three microcontrollers (MKR1000, Mega 2560 and Raspberry Pi B) to simply control a robotic car via SSH on a computer. The idea is to have a computer connected to a Raspberry Pi via ssh, which in turn is connected as a client…
This project allows data from ECG electrodes to be read and processed in order to predict atrial fibrillation. To do this, the system will use a Machine Learning system (TinyML) which will compare the acquired data with other pre-set ones. The system acquires the signal of the ECG electrodes through an AD8232 module, which analog…
The project consists of creating an eggbot, an artistic robot that can draw on spherical or egg-shaped objects using an Arduino Uno development board. This project is a good introduction to CNC machines because you can learn the concepts of firmware and hardware that involve them in a fun way. The robot needs two stepper…
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!
