I bet unless you really use them, you may always be thinking of knocking them all out before using them in your project. Well, if you feel the need of having a simple relay module, with just the basic components, you are at the right place. In this tutorial I am going to show you…
This video is a tutorial on how to control Common Cathode 8×8 LED matrix without the use of any driver chips like MAX7219 and corresponding libraries but just an Arduino Nano. More info
This post is an introductory guide on how to use the Fingerprint Sensor Module with the Arduino. We’ll show you how to enroll a new fingerprint ID, and how to find a fingerprint match. More info
Congratulations on becoming a Raspberry Pi 4 explorer. We’re sure you’ll enjoy discovering a whole new world of computing and the chance to handcraft your own games, control your own robots and machines, and share your experiences with other Raspberry Pi fanatics. Getting started won’t take long: just corral all the bits and bobs on our checklist,…
This article is a getting started guide for the ESP32 development board. If you’re familiar with the ESP8266, the ESP32 is its sucessor. The ESP32 is loaded with lots of new features. The most relevant: it combines WiFi and Bluetooth wireless capabilities and it’s dual core. From OpenStore More info
KiCAD has a rightfully earned image problem regarding beginners. The shiny new version 5 has improved things (and we’re very excited for v6!) but the tool is a bit obtuse even when coming from a electronics design background, so we’re always excited to see new learning material. [Mike Watts] is the latest to join…
The air data computer Asgard is out. It is a unit designed for DIYers, size and weight are compatible (fixation tabs have the same dimensions of standards servo tabs) with low-cost RC applications. Some aspects will be changed as per users feedback. The ADC is an essential avionics component and you can find a reference configuration for the Asgard-ADC…
For all the Star Wars lovers, especially those that liked the Episode VII, a must DIY project from DFRobot blog: the home made BB8 Droid! Today, I’m going to teach you how to build a working, life-sized, phone-controlled Starwars BB-8 droid! In this tutorial, we are only going to use household materials and a little…
An area of application of Computer Vision, one that has always fascinated people, concerns the capability of robots and computers in general to determine, recognize and interact with human counterparts. In this article we will take advantage of the availability of cheap tools for computing and image acquisition, like Raspberry Pi and his dedicated video…
Let’s see how to use the Camera Pi module, a quality photo video camera, purposely designed for Raspberry PI, to acquire the first knowledge concerning Computer Vision, to recognize colors and shapes. Camera Pi is an excellent add-on for Raspberry Pi, to take pictures and record quality videos, with the possibility to apply a considerable…
Robots provided with autonomous operation capabilities and, particularly, those sporting sense organs similar to the human ones, have always tickled the fancy of science fiction writers and screenwriters. As always happens, from a certain point in history, even official science has started to deal with the subject, at first with the so-called “strong theses”, whose…
Once experimented with REST technology and with the “Bridge” communication mode, we can introduce a project that achieves something difficult so far with an Arduino board: writing a web page, to be run by Linino’s internal web server uHttpd, to manage the pins of Arduino with REST, but via a web page. We will show…
