We create NeoPixel light installations with Fishino and NodeMCU controlled via Wi-Fi from a PC or Raspberry Pi using a Python library. A few years ago, the American company Adafruit Industries transformed the LED market by introducing NeoPixels, RGB LEDs that incorporate their own controller in a single package. Adafruit aimed to simplify LED management…
In this video, IoT (Internet of Things) is introduced, which literally means “internet of things.” The video begins with an introduction to IoT and then provides an overview of its application fields. Subsequently, it delves into discussing the hardware required to make a device capable of connecting to the internet, specifically analyzing two boards:…
There are numerous ESP8266 modules available, and they are often used in battery-powered IoT applications that, with the correct configuration, can run for months. In this guide, you will learn how to power an ESP8266 using lithium-ion batteries and how to configure it correctly. You will also be able to simulate battery life…
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 at this project! The system consists of a sensor module that measures various environmental variables, which sends its…
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 this project we will see an alternative Wordclock using 3D printed letters, which will move through a magnetic…
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 notification to your smartphone. We will use a magnet with a reed switch to determine if the door…
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 crystal, it is difficult to imagine how text and numbers were displayed before their advent; Well, those who…
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 page from ESP8266 and finally you will be able to open the door using your phone. We…
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 two special sensors and controls a pump through a relay module. Everything is powered by a power supply…
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 see how to simplify the process by creating a device that accurately measures cuts every time. You won’t…
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 that allow the creation of air bubbles inside 8 tubes. There are also a 0.91 “display and 8…
