Use RC522 RFID with Arduino and OLED – RFID lock

RFID is one of these technologies that change how we interact with other electronic devices and things in our environment. It is used in every application where some unique identifier is required, from retail to security and is also leading the path along several futuristic innovations with RFID based human implants among others. This wide […]

A Colorful Christmas Star with Neopixel LEDs

A technical Christmas decoration, created by means of Neopixel LEDs and controlled via an Arduino Micro board, that takes up a minimal amount of space. With the Xmas holidays approaching, we always try to propose a solution or another, one that is capable of combining tradition and innovation, so to avoid the usual or the […]

Halloween Scare Project with 12F683 and ISD2532

Halloween is coming up and it’s time to do some pranks. Everyone likes Halloween and I’m no exception. Every year me and my wife decorate the house with lot’s of bugs, spider webs, creepy posters and of course lot’s of Halloween candy. While making the normal Halloween preparations I came up with the idea of […]

Smart Power Switch for Arduino

This project works like most digital watches when you turn them on, it shows you the needed information and after a while goes off to preserve the battery. A typical Arduino consumes about 40mA of current in an idle state while the atmega328p consumes around 20mA when in the same state. We can conserve this […]

Communication between 2 arduinos with NRF24L01

While building Arduino or any other microcontroller platform project over time the need will arise to establish communication between two of the Arduino boards or microcontrollers for data exchange and/or control. This communication could be achieved using either wired or wireless process. For wireless communication between devices, quite a number of options exist including WiFi, GSM/GPRS, […]

Using SG90 Servo with An Arduino UNO R3 Board

Today, I will show you how to use a servo motor with an Arduino. This tutorial is ideal for beginners because it is easy and it gives them the foundation to build interesting projects like robots for which servos are commonly used. Servo motors are high torque motors which are commonly used in robotics and […]

DIY An RC Arduino Powered Fan Rocket

Maker and 3D printing expert James Bruton based in the United Kingdom has created a new Arduino project in the form of a unique type of craft thanks to its electric ducted fan (EDF) propulsion system. Watch the demonstration video below to learn more about the unique Arduino project. The Arduino hardware autonomously controls the […]
