This project is not only an intelligent coffee machine with smartphone control but also allows you to graphically view the temperature trend. It can be controlled via Bluetooth or simply fill up with fresh water and the system starts automatically! Developed on Arduino Nano, it uses an ST7920 display, an HC-05 Bluetooth module, a Dallas…
In this project we will see how to make a glove that, simply by tilting the hands, makes something seem frozen in time, or move it back and forth in time. The effect is based on a light that, flashing at a certain frequency, will make moving objects appear as if they were stationary or…
If you have a dog and want to keep it entertained even when you are out of the house, you could do a similar project. It is a device that throws the ball after inserting it into the upper cavity, so your dog can play in total autonomy. The project is based on a Teensy…
In this project we will see how to make an RC controller that communicates using a 2.4 GHz radio signal. This RC controller was designed to be used with a quadcopter. The radio control was made in 3D and uses an Arduino Nano that sends, through an NRF24L01 module, the data read by two analog…
The “light painting” consists in photographing moving light sources and thus obtaining very particular and creative images; in this project we see how to build a bright skateboard for this purpose. We used an Arduino Nano as a microcontroller, the case was 3d printed. We connected a button and a switch so that we could…
The idea to the creator of the project was born walking at night with his dog, and noting how the temperature changes between the inhabited areas and the fields. Just to measure the temperature and humidity, he wanted to create a small and handy device to carry around on walks. There are tons of weather…
Kutluhan Aktar has a gradually growing Twitter account for his website. Most of the time he forgets to check the follower trend to measure their growth. So, he decided to create this system to be placed on the desk that shows his account information, specifically: current follower count, current account name and ID, three previous…
In this IoT project, we will see how to create an IoT module that allows you to turn on 4 lamps, or any other load, controllable by Google Assistant and Alexa. As you can see from the image above, the system is based on a NodeMCU that controls a 4 relay module. In the absence…
In this project we see how to make a lamp that can change its colour according to the environment, using the Arduino Nano microcontroller. We must therefore create an electronic circuit that takes a color as input and outputs the relative light. The most important material in this project is the TCS34725 RGB sensor (another…
In this project we will see how to build a smart bin. The system detects if the bin is already full and opens automatically when someone approaches. What gives it an edge over other smart garbage cans on the market is that it uses a touch screen display that allows the user to interact and…
In this project we see how to build a dual axis solar tracker with photovoltaics. The photovoltaic itself will power the tracking system, so no external power source is needed. To track the sun, we used four LDR sensors, Arduino UNO compares the data provided by them to rotate the panel in the direction with…
Let’s see how a climatic chamber was built with recycled and easily purchased components. This was designed and built to perform gravimetric experiments in different humidity and temperature conditions. The system is based on Arduino Uno, which controls a nebulizer and a peltier cell to set, respectively, humidity and temperature inside the chamber, which are…
