En él nos descubre el nuevo módulo 3G para Arduino de Cooking Hacks con el que podremos construir una divertida alarma que nos enviará la foto de nuestro intruso directamente a nuestro correo, además de avisarnos por un mensaje sms a nuestro teléfono móvil sin necesidad de tener conectado nuestro Arduino a internet constantemente, pues lo hace todo a través de la red móvil.
Vamos a construirnos una alarma totalmente casera, a través del sensor de ultrasonidos, escanearemos continuamente el espacio situado enfrente suyo con un radio aproximado de 30º, cuando algún objeto o persona se sitúe en su campo de actuación a una distancia inferior a la que establezcamos, haremos sonar una alarma, tomaremos una fotografía, el Led RGB que antes estaba verde, pasará a color azul y daremos 10 segundos para poder desactivar la alarma a través de nuestro teclado matricial, si la desactivamos, volverá de nuevo a escanear el campo, pero si no!! Reproducirá un sonido contundente y se dispondrá a mandarnos un sms a nuestro teléfono móvil y la fotografía a nuestro correo electrónico.
Part 1
– General introduction to microcontrollers and embedded systems
– Basic eletrical concepts, use of breadboard for prototyping circuits.
– Arduino “Hello,world”: build a blinking LED circuit
– Controlling more than one LED
– Using Pulse width modulation to control LED brightness
– Interfacing a seven segment display
– Using the arduino digital inputs: interfacing a mechanical switch
– Using the analog inputs: sensing light using an LDR
– Potentiometer interfacing
– Reading temperature
– A quick introduction to the Python programming language
– Serial port interfacing (Python will be used to write PC-side code)
Part 2
- The second part of the workshop will be a demo. An Ez-Chronos sports watch which contains an accelerometer as well as a radio will be used to control an LED attached to the Arduino board.
Impressing automotive hacking lets this FIAT car moving by the number of “like” from the Guarana Antarctica Facebook Fan Page. The advertising idea is simple: let the social audience support this Sau Paulo to Salvador trip to reach the Carnivalby commenting / “liking” the page. The onboard Arduino ADK (connected to a tablet and the internet) allows the car going on by a certain amount of meters (apparently one “like” is 10 meters, while each comment lets the car go ahead for 20 meters).
As a hobbyist, we often want to extend the functionality of our arduino board. In order to minimize wires and maximize functionality, we design special need-based ‘shields‘. A useful step by step tutorial that I found here , breaks down the process into the following stages:
For those of you who are addicted to merge new technologies to interface-archeology here is a new ‘Tworsekey’. A vintage looking tweeting device which takes input in the form of morse code and tweets the output. It features arduino and the ethernet shield. The sketch can be downloaded from here. Needless to say that the design is open sourced.
In case you want to build it, the design details can be obtained from here.
BetterNouveau is organizing a promising workshop about circuit milling with Roland iModela in Turin. Massimo is going to walk you around milling your own shield.
[...] you’ll learn to design and create your very own Arduino shield (‘shields’ are boards that can be plugged on top of the Arduino extending its capabilities). We’ll start from schematics, create the layout and make real prototypes on-site: become a pro Arduino user and learn to design circuits with the Eagle PCB software and make your own Arduino Shields using the Roland iModela desktop milling machine. D.I.Y shields are the best way to move your project from a breadboard-based approach into a professional prototype.
[Enrico Bassi] from FablabTorino brought to the extent the use of the Roland iModela, using the little (and inexpensive) desktop milling machine for pcb milling. (in the picture we milled the overexposedFritzing Parking Assistant).
Arduino counts with two twitter accounts: @arduinoteam is the one used by the team to report about things we think matter to the community. @arduinoblog is twitting for every blog post, and allows us handling answers on our blog.
