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...

Do you know what a “Wordclock” is? A Wordclock is a clock that displays the time by lighting up certain letters, contained in a matrix, in order to write the words corresponding to the current time. In...

In this project we will see how to use Home Assistant software to create an intrusion alarm system for your home. The system will basically detect if the door is opened without authorization and then send a...

We pick up the fascinating Nixie tubes through displays based on packages of laser-engraved plexiglass plates, illuminated by Neopixel LEDs. For those born in the era of solid-state displays, be they LED, 7-segment, dot-matrix, or even liquid...

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...

The project stems from the need to be able to view the water level in a tank and to control a pump accordingly. The device is based on an ESP8266 module which reads the water level through...

A simple CD holder can be transformed into a single object, using addressable RGB led strips. 2.5m of WS2812B LED strip controlled by an ESP8266 were used to customize the CD holder. More info

If you have a circular saw you probably use a tape measure every time you want to cut a piece of wood and make pencil marks after you find the desired length. In this project we will...

In this project we will see how a clock was created that displays the numbers through air bubbles inside tubes. The system consists of an ESP8266 which, through an I / O Expander MC2301, controls the solenoids...

RoundyPi is a round LCD display based on RP2040 along with compact and stylish 1.28-inch display module of 240×240 resolution, 65K RGB colors, clear and colorful displaying effect, expand its engagement with your project. RoundyPi comes with...

An inexpensive WiFi repeater that you can easily build at home. A single 4800mAh battery’s expected run time is about three days. The WiFi module used is an ESP8266-01 powered with a 18650 battery. By modifying the...

In this project we see the development and construction process of a solar-powered irrigation station. This also collects atmospheric data and soil moisture and sends them in real time to the cloud for remote monitoring, also independently...

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 the age of Zoom, Messenger and Snapchat calls, communication around the world has become commonplace. But what if you could go back in time and painstakingly write the message one beep at a time? With this...

In this project we will see how to build a digital scale that uses the ESP8266 microcontroller with a load cell (and its HX711 converter). The scale is able to measure weight with gram accuracy, the sensor...

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...

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...
