ARDUINO+SERVO TUTORIAL
– April 26th, 2010
Basic, therefore useful, Arduino/servo tutorial.
In today’s post, I’ll show you how to connect a simple servo to Arduino. It may sound difficult, but it’s really easy.Hardware
- *Servo (1x)
- Arduino Board
- 3 Wires

PUTTING AN ARDUINO DIECIMILA TO SLEEP & WAKING UP
– April 26th, 2010
In this series of blogs I will be describing how to put an Arduino Diecimila into sleep mode, thus reducing the power consumption of the device. This can be quite useful (even necessary) when you are powering your Arduino via a battery and/or solar panel.
Consumption in the Arduino…
There are several devices on the Arduino Diecimila that consume battery power, including:
- ATmega168 micro-controller
- FT232RL USB UART
- The power regulator
The Arduino Diecimila I have uses about 35mAmps during normal operation and in power-down sleep mode about 15mAmps. There isn’t a huge difference here, the main problem is that the power regulator draws 10mAmps, irrespective of the sleep state the Arduino is in. The ATmega168 micro-controller draws about 0.05 mAmps when in power-down sleep mode and 20mAmps during normal operation.

CEB PRESS: BUILDING ON REPRAP AND ARDUINO
– April 26th, 2010
The CEB automation for the Liberator Beta 2.0 open source CEB press builds on other open source projects. We are using: (1), power drivers from the RepRap project for driving the solenoid valves; (2), Arduino as the controller-brain for the brick-pressing logic; and (3), a Ubuntu 8.04 Linux laptop for programming the logic. The advantage of this approach is that utilizing existing modules builds on mountains of prior work and documentation. In the limit of an open source economy – one would in principle be able to take well-documented and available parts, components, and modules to become a Maker of all the surrounding world. This is a deep part of autonomy and of evolution to freedom.
If you happen to visit “Open Source Ecolog, Building tools for replicable, open source, post-scarcity resilient communities” you may jump it this interesting ongoing project on an opens source earth-compressing machine.
ARDUINO CHEATSHEET
– April 23rd, 2010
Thanks God, finally someone made it! I was starting not to be able of following Arduino’s development, this Cheatsheet from The Mechatronics Guy came to save me.
(c) 2010 Arduino Cheatsheet by The Mechatronics Guy
The beauty of it is that you can get all the knowledge at once, but also that the platform has now reached the highschool-exam level. People need the cheatsheet to make it to the exam. I just love it, I will print it and put it at K3′s lab here in Malmö. I bet you a Swedish Crown a lot of people will do the same.
Would you like to get a PDF version of the sheet? Click here. Thanks to Make for the link.

CANAFOTE – ARDUINO NETWORK INFRASTRUCTURE (IN SPANISH)
– April 23rd, 2010
(c) 2010 by Canafote project
Proyecto Canafote just got the Open Source Software Price from Sevilla’s University in Spain. I can’t read Spanish, but [Mr Cuartielles] (from Arduino Blog) does:
Este proyecto se basa en la tecnología Arduino que es un proyecto de hardware libre. El objetivo de este proyecto, es el envío de una serie de datos obtenidos por sensores ya sea de temperatura, humedad,etc. por ethernet o por xbee, creando una red de sensores que a parte de obtener datos también los trata y reacciona ante ellos.
What means:
This project is based on Arduino technology, which is an open hardware project. This project’s goal is to send data coming from sensors, whether they messure temperature, moisture, etc over ethernet or Xbee creating a sensor network. This system, besides obtaining data, is able of reacting towards them.
ARDUINO CHEAT SHEET
– April 23rd, 2010
Nice Cheat Sheet for Arduino Classroom Tests 
I really love cheat sheets. In a lot of cases they can take the place of an entire manual. So I was surprised, given its popularity that I couldn’t find a single-page reference for the arduino online. I tried to make a sheet that captured all the things I hit the reference for while programming. What data type does the millis() function return? How long till that overflows again? How large can a long get? What baud rates can the serial handle? Any other things you’d like to see added, send me an email and I’ll stick them on Rev 3!

In this time of blogs and Web 2.0. aren’t you missing good old html pages? Well, that is what you will see when you visit the Proyecto Canafote website. This project just got the Open Source Software Price from Sevilla’s University in Spain. It’s page states:
Este proyecto se basa en la tecnología Arduino que es un proyecto de hardware libre. El objetivo de este proyecto, es el envío de una serie de datos obtenidos por sensores ya sea de temperatura, humedad,etc. por ethernet o por xbee, creando una red de sensores que a parte de obtener datos también los trata y reacciona ante ellos.

The network needs a server that will collect al the data and eventually report the actuators in the network when they should make a move. The wireless part of the net needs an ethernet-Xbee gateway to connect. The server is written in Python and runs on linux, and creates a series of graphs coming from the different sensors on the fly.
There is a lot to polish in the website, regarding documentation. But dudes, this was made by a student in his spare time. Can you imagine how far this could go if we all give him a hand in doing things like translating his documentation videos to other languages? Just in case you are interested in the legal issues behind all this, everything is under GPL3, great job!!
The project owner, Alvaro Neira Ayuso, is publishing a blog to document the process of making the project. Congratulations for that award!!
ARDUINO 56×8 SCROLLING LED MATRIX
– April 22nd, 2010
From Hari:
After several tries, I was able to fit seven 8×8 matrix side-by-side on a breadboard and not have wires crossing over the displays. The key is to put the chips on one side (rather than above or below) the matrices. You can put another 7 driver chips on the right side and double this to a fourteen 8×8 side-by-side matrix!!!By customizing the breadboard, I was able to rearrange where the power buses are and use them not for power, but to have a common bus for the eight anode rows shared by all displays.Considering each display require only 16 wires, I was surprised how much time this took to wire up. One thing I learned from this project is that I should not be so stubborn in using the correct wire colors. I ran out of wire of correct length and color and that allowed me to work faster.
