Arduino Seismograph V2.0 (Concept)

This is the Arduino Seismograph V2.0, this is just the concept of one idea, it's no longer use an piezo buzzer like my previous seismograph, this one use an optical mouse as the input sensor, of course this idea has some pros and cons.

The Pros:
-It has a high level of sensitivity to the movements.
-Capable of detect the Vertical and Horizontal movements.
-Only use 2 digital inputs.

The Cons:
-The installation problem, since it will be hard to desing the way that the ccd sensor of the mouse sense the moves of the ground, I'm thinking leave the mouse static and some sort of plane with an stripe or square pattern that will move up and down with an weigth above (check image).


-The possible friction since the sensor needs to be very close to the plane to detect the movements.

After all this is just an concept, so it can be or not built.

I leave you the video of the test #1.

Arduino and SheevaPlug together

Ken Shirriff from Arc Language Blog has finaly (with hard work) communicated the Arduino and the Sheevaplug mini server, giving to the Arduino strong abilities of home automation, surveilance, monitoring and also log archiving.

He started doing an little example of home monitoring, recording the ilumination on his room by reading the light in a photocell conected to the Arduino who then sends the data to the sheevaplug through a serial conection, the sheevaplug generates graphics that can be check by accesing it through a web service.

The WII Motion Plus decoded!!

That's correct the WIIM+ was decoded, and we expected that because this device like the Wii Nunchuk communicates through the I2C bus, making it easy to interfaze with Arduino.

knuckles904 wrote in his BLOG how to make the connection with the Arduino and the scketch to establish communication, the code is well commented so it will be easy to follow, for those who want a device with 6 sensors at good price, and only use 2 Arduino's analog ports without the need for conversion from analogue to digital because the WIIM+ do it for you.

Seismograph Arduino

I present my latest project with the Arduino, a Seismograph very simple and easy to build, consists of only one Arduino, a piezo buzzer a couple of resistors, springs, a deadweight and handmade paper clips stand(with a little more time and patience could be better).

The data are sent to my computer through the serial port to a program written in Pascal which display the data as graphs of lines.

Check the video.

Fire Fighting Robotics Platform

A stylish fire fighting robot, controlled by Arduino with caterpillars as transport system with infrared distance sensors, scanning surroundings in search of fire to extinguish it with a small fan at the front of his chassis, if his effort to extinguish the flame does not works its activates the panic mode which is get out of there as soon as possible to avoid becoming a pile of melted plastic and toast circuits.

A dragon that wipe out fire... Yep with Arduino you can do anything.

Infrared radar with graphical representation

Here an excellent example of use for the Sharp infrared distance sensor GP2Y0A21YK, mounted on the frame of a robot the sensor with the aid of a servomotor (for panning) performs a scan about 180 degrees, then the data is sent from Arduino to an Processing SKETCH written by Cory Barton which captures the data to generate a visual representation like a radar, a truly great little project.

Magnetic levitating with Arduino

If you get an Arduino board a coil and an hall effect sensor, you get a magnetic levitating device.

Mekonik brings us this excellent example of the use of A / D skills of the Arduino, as its first Arduino project.

Alcohol sensors for sound

In case you tire of photocell for sound (ahh but who could?), here's a demonstration using an entirely different type of sensor -

Short demonstration of the device used for my "Nunk on Droise" (Noise Under the Influence) performances. The device is constituted of three alcohol sensors connected through an Arduino board to a computer running a Pure Data patch. The bars on the computer's screen correspond to the content of alcohol detected by each sensor. Sorry for the sound that is really bad.

They seem quite sensitive - performing at a club/bar with these may prove a bit unruly, possibly quite fun.

Arduino Robot - ArBot 01

I present to you the fastest and easier robotic project to build with the Arduino, this ROVER
consists only of a Sharp GP2Y0A21YK distance measuring sensor, a Pololu Dual Serial SMC01A motor controller and two DC motors with their respective GEAR BOX (in my case I buy pololu robotic kit that came with the ball Caster, tamiya gear box and chassis).

As the code is simple, the Arduino through serial connection with SMC01A sends orders to stop, turn right, left and backwards.

Arduino Sketch

The programming is very basic when detects a obstacle (about 15cm) stops, then turn left to take a reading of the distance, then turn right and take another reading, after the two distances has ven taked he choose the best option in this case the greater distance, turn to that side and continue.

Video below.

It needs a little changes to the program once get improve I show you the videos.

Arduino TEMPMAN

Well to start with the right foot let me show you this proyect which consist of a termisistor Arduino and a computer network.

The goal was to read the temperature with termisistor connected to an Arduino analog pin and with the serial interface send the data to our computer which will serve as a "server" which sends a message through the service of NET SEND Windows (google to know how activate it) to computers in network the outside temperature through a program written in Pascal running on your computer.

Here the program which I call TEMPMAN (Temperature Management) the Arduino code and an Excel spreadsheet for calculating the ADC termisistor.
