This page explains how to build an RFID reader with just an Arduino (Nano 3.0 was used in testing, but other models may be compatible), a wire coil made by hand, and various affordable common components. Credits The hardware and software designs for this project are based in part on the ideas, code and schematics […]

I started learning Arduino a couple of years ago and started playing around with a 16×2 LCD display that uses the Hitachi HD44780 chipset. I soon found out that the screen provides 8 character slots that are customizable. I found a project in which someone used the slots to create their own special characters, which […]

What Language is Arduino?   You may have heard of Arduino already it is one of the most famous microcontroller boards used for hardware interaction and designing various interactive projects. And have you ever spared a thought to think about which programming language it is using in the backend?  This article will explore the foundational […]

I was supporting a group of student on their graduation project. One of the difficulties they faced was on controlling an A/C unit with Arduino microcontroller. The first experiment we tried to work it out was by record the A/C remote control beam signal for each needed button by using the IRrecvDump code with IRremote […]

I am presenting a compact design of a stripboard Arduino board (DIYduino) that includes a 2A motor driver and has additionally the functionality of a sensor shield. The 2-channel version cost approximately $29.43 and is more affordable compared to $39.00 for a commercially available system consisting of an Arduino Uno, $21.50, a sensor shield, $8.50, […]

For my internship at Create Digital Music/Meeblip I’ve created quite a fun little synthesizer. This thing is meant to be more flexible than other synthesizer by making it completely independent; it is battery powered, has its own amplifier/speaker and is controlled by a manually operated sequencer. Inspiration for this form comes from my frustrations with most synthesizers: […]

INTRODUCTION This DIY Arduino project explores various ways to enable communication and connectivity between an Arduino board and external devices or networks. Specifically, it focuses on three components – Arduino serial communication to Processing, Arduino with Ethernet shield, and Arduino with GPRS. The Arduino is an open-source hardware and software platform for building electronics projects […]

This circuit demonstration showcases a random LED flasher controlling twenty lights. LED flashers and sequencers are commonly employed in decorative lighting applications to produce aesthetically pleasing color patterns. Rather than steadfast illumination, these systems cycle LEDs on and off in either a predetermined sequence or at irregular intervals. The latter approach generates a more dynamic, […]

Este es el primero de 5 instructables que surgieron del Instructables & Sugru build night (and day en nuestro caso) que hicimos en el Laboratorio de Juguete, el 20 de julio del 2013:  una Resistencia Flexible o Flex Sensor hecha con Sugru y polvo de grafito: ——————————————- This is the first of 5 instructables from Instructables […]

Remote visualization of real-time sensor data. This tutorial describes in detail how to use the free SensorMonkey service to push real-time sensor data from an Arduino to a webpage for visualization using Processing.js. No server-side coding or Ethernet shield is required. A standard, run of the mill Arduino will work perfectly. You’ll also need a sensor to […]
