I2C EEPROM plus Temperature Sensor breakout board

Posted on February 26, 2013 by R-B 3 comments

This tiny breakout board carries Microchip’s 24LC512 EEPROM and MCP9802 temperature sensor devices, both of which support I2C protocol. This board can be used for both sensing the ambient temperature and storing it. The MCP9802 is a digital temperature sensor with an user-selectable resolution from 9 to 12 bit. It can measure temperature ranging from -55°C to +125°C and notifies the host microcontroller when the ambient temperature exceeds a user programmed set point through its ALERT output pin. This board allows you to store up to 32000 temperature samples when you use the sensor in high resolution mode (12-bit, 0.0625°C)

If you want to get into the world of Arduino but not sure where to start from, you should check this comic book introduction to the Arduino platform from artist Jody Culkin. The comic is Creative Commons-licensed and can be downloaded in the PDF format from here.

Amicus18: Arduino-style platform for PIC fans

Posted on September 4, 2011 by R-B 7 comments

Arduino needs no introduction; it is an easy-to-use yet powerful open source embedded system development platform that has gained huge amount of popularity in past few years, specially among hobbyists. The standard hardware consists of an 8-bit Atmel AVR processor with on-board headers providing access to its I/O pins. The processor is pre-programmed with a serial bootloader that simplifies the uploading of user programs to the on-chip flash memory without the need of any external programmer. Because of its low cost, user-friendly software development environment (open-source C/C++ like programming platform), rich set of libraries, and tons of resources available online,

Voice controlled robotic vehicle

In this video, Carlos Asamat describes an Arduino driven speech controlled robotic vehicle. The required components and modules to construct this robot can be purchased from RobotShop. The voice commands are processed through a speech recognition hardware module and are transferred to the vehicle through Xbee RF communication modules. The speech recognition module is controlled through an Arduino Uno. The robotic vehicle to be controlled is the DFRobotShop Rover,which is a very versatile programmable robot platform. Besides the mechanical structure of the robot, the DFRobotShop Rover PCB also incorporates a standard Arduino Duemilanove (surface mount ATMega328), L293B motor driver, voltage regulator and an additional prototyping

Arduino based water usage meter

Posted on March 10, 2011 by R-B One comment

This project (from Teague Labs) was intended to study the usage of water for various purposes and how this information could affect behaviors of persons using water when displayed on real time. The water meter sensor used in this project is INS-FM17N from Koolance. The sensor is directly interfaced to an Arduino that acquires and send data to a web server to make it available online.
