In the last part of my tutorial about the A4988 driver, I’m going to explain how to build a controller to adjust speed and rotation direction of a stepper motor. Schematics I used the same setup introduced in a previous post: an Arduino Uno; a LCD Keypad shield; a Pololu A4988 driver mounted on a breadboard; a NEMA17 stepper …
Ci aspetta un week end intenso: mentre Davide e Pitusso tengono il workshop base di Arduino a Matera, a Venezia (presso H-farm ) si tiene il secondo codemotion di quest’anno, che vedrà il nostro Cristian Maglie raccontare l’Arduino Due e il cammino che abbiamo intrapreso per realizzarla. Arduino sponsorizza anche l’Hackaton sulle emergenze, offrendo 10 Arduino …
Invention of a new Open Source mechanical musical instrument Following the « DYI » trend, here comes a musical automaton created by [EricDuino]. This Arduino based autonomous robot is named « Line Follower Organ », « Orgue Suiveur de Ligne » in its maiden language. What’s new with this instrument is that it moves along its partition in order to play …
Brazo robot dibujante V2. (Monstruosidad tecnológica) Los resultados del brazo robot dibujante anterior no tuvieron una gran resolución. Mi idea inicial era hacer que pudiera escribir y eso resultaba impossible. Esto se debía principal mente a que cada paso de los motores paso a paso que uso es de 0.9° (400 pasos / rev). Cada …
A smart choice: The mini SWARM is a versatile USB stick-sized wireless Arduino development board. It’s as powerful as the Arduino Mega and has the wireless capabilities of an XBee radio, but we’ve made it a fraction of the cost of an Arduino + radio shield – cheap enough to leave in any project. A wireless …

The objective of this project is to build an Arduino voice shield to empower thousands of voice related applications! All this mostly thanks to an integrated ISD1790PY chip. This particular voice/TTS feature can be useful to integrate voice messages in alarm systems, to implement generic I/O controls in home automation or even in home security …
In this post, we will learn The-Desktop-Device-a-Customizable-Desktop-Assistant: The Desktop Device is a small personal desktop assistant that can display various information downloaded from the internet. This device was designed and built by me for the CRT 420 – Special Topics class at Berry College which is lead by Instructor Zane Cochran. This instructable will go …

Automated Solar Tracker Using Arudino Nano V2: Solar Tracker Project. To explain how solar trackers work and how to design a tracker, The goal of this project was to improve my old solar tracker, as well as add more bells and whistles to make it more interactive. Some changes to the design include a new …
Automated-Point-to-Point-Model-Railroad-With-Yard-Siding: The Arduino model opens up tremendous possibilities in railway road, especially when it comes to automation. It is a continuation of one of the previous projects. The project consists of a railroad layout identifying a train and placing the train along the yard. With the help of feedback mechanism and train and turnout, all …
