By: Alex Danovich, President San Francisco Circuits We live in an exciting time where we see a resurgence in electronics as a hobby. Mass production has wiped out a generation or two of kids learning to build radios from scratch with their mom or dad. In the good old days, not sure when, you had …
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 …
