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...

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...

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...

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...

In this project we will see how to make a thermometer to measure the temperature in the room with a measuring range from 10 degrees to 35 degrees Celsius and an accuracy of 0.5 degrees. The temperature...

In this project we will see how to make a smart pot that can show the emotion of a plant. It uses a soil moisture sensor to monitor the state of the soil and then displays an...

In this project we see how to build an IOT-based dust monitoring system that can measure surrounding dust, send data over the Internet, and monitor the long-term value graphically. We use a Sharp gp2y1014au0f particle sensor which...

Voltlog is hacking his car console through the CAN bus. According to the author, for his projects, the available CAN bus interface cards are somewhat lacking. So he designed his own wireless CAN bus hacking and development...

Peter Balch, reading an IEEE report on speech recognition from the late 1970s, wondered if, with a normal Arduino Nano, it was possible to obtain the results of a computer of the time. Comparing the two tools...

If you create PCB with SMD components or you are a repairman you surely know how important and convenient a hot air soldering station is. With this project, you will be able to learn how to make...

With this project we will see how to make a solar powered wireless weather station using an ESP32 WiFi module and some common weather sensors. The weather station is fully solar powered, so you don’t need to...

Anyone can learn robotics, but what if there was a practical and inexpensive approach? This is where “Boca” comes in. Boca is a 3D printed open source platform for manufacturers and researchers interested in exploring control theory...

There are probably more than a hundred Arduino-based printing machines on the internet with instructions available for making them. What makes this project unique is the built-in camera and screen. Other plotters must be connected to a...

In this project we see how to build a logic probe, that is a complete, simple and effective instrument that allows you to measure digital logic levels 0 and 1, both in TTL and CMOS technology. The...

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...

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...

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...

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...
