Pedro 2.0 is a fully open-source project, designed to be accessible and customizable for everyone. It’s easy to assemble no screws, no glue, no tools required! Perfect for makers, students, and educators looking to explore robotics and program...
Hey, smile! Hello everyone!I made a small project with LEDs and a MAX7219 matrix.
The blue board contains an ATMega8AU-TH (but it should work with any ATMega8-AU), I bought several ICs, cheap of course (I don't think I need to advertise the website),...
This is code I cooked up in the Arduino Forum a few days ago to help someone who wanted to hack their kid's Powerwheels/Peg Perego 2WD ride on toy using a Sabertooth 2x60 motor controller.
I was never happy with Dimension Engineering exampl...
What is MQTT, and how is Arduino combined with MQTT for Internet of Things applications? These questions may have crossed your mind after reading the title.
In this article, we will learn how MQTT (Message Queuing Telemetry Transport) uses low-bandwi...
Created and installed rpi4 based router to access internet. This also has PoE hat on it..
Introduction
Recently, I was having a need for a router or a wifi range extender. Because, the high speed internet in my home router was not connec...
A stepper motor is an electric motor that moves in discrete steps. Each step is a fraction of a full rotation, and the motor's position can be controlled precisely without the need for feedback systems. This makes stepper motors hi...

DC motors power everything from toothbrushes to robots. Controlling their speed and direction is crucial. In this project, we'll use an Arduino, a potentiometer, and a MOSFET transistor to control a DC motor. Our versatile, low-cost design can al...
Despite numerous precautions, fire accidents still occur, risking human lives during rescues and firefighting. With advancements in robotics, we can now replace humans with robots for firefighting, enhancing efficiency and safety.
In this project, we...
Just a fun simple project using the Arduino Beetle and a Z502 Dekatron tube to create a simple spinner out of this classic display tube. The design of the circuit was adapted from the circuit diagram I attached from "Dekatron Drive Basics M. Moo...
This project is not entirely Arduino, but I think it is a good example of how Arduino's can be incorporated into other systems. The initial design of this project was to automatically open and close the cat door and track the cat's activity a...
This is an old restoration project of an old battleship phone which I retrofitted with an Arduino UNO and a BCD MP3 player module. The front of the phone has a selector switch which I tied to the inputs of the Arduino which then sends a BCD code to t...
This project started with an old nixie tube display rack and an Arduino mega 2560 with DS1307 RTC. The nixies are driven with the SN74141 BCD to nixie drivers. This project was a lot of fun to build it also has a temperature and humidity sensor DHT11...

Hi
Looking to see if anybody in interested in doing a project for me
I am trying to convert a 2 wire serial stream of different protocols data consisting of bcd address pulses and values coming in and display the various data parts and to...
Traffic lights are an essential part of our daily commute, keeping intersections safe and organized. But have you ever wondered how they work? In this blog, we'll embark on a fun project: building a basic traffic light controller using an Arduino U...
Hey element14 community,I'm here to introduce an exciting project that I've been working on: the Spark Analyzer. This isn't just another power supply unit; it's an IoT-enabled device that's hopefuly going to change how w...
community.element14.com/.../IMG_5F00_5277.movThanks to the element14 video on how to use the SN74HC595 to add outputs to an Arduino, I was able to build the following.
I‘m a piano technician by trade, but have always wanted to build a...

If there is a date to show affection and love to that special person we have in our lives, that date is Valentine's Day. A gift that we always have in mind is to give red roses for the meaning they have, but after a few days they begin t...
This is a simple project, very easy to make and with few modules, but it is very useful, since it shows the time, temperature and humidity in a room or where the DHT-11 sensor is placed. To show the time it has been chosen to show only t...
