A thermocouple datalogger based on the Arduino platform & (previously, rolling your own thermocouples )… It never hurts to collect more data, and I often find myself wanting to record temperatures from a few extra animals. Most (all?) commercial thermocouple dataloggers that will record temperatures from multiple thermocouples cost several hundred or thousands of dollars. I set out to put together a relatively cheap 8-channel thermocouple datalogger based on the open-source Arduino development platform. Thermocouple Type-K Glass Braid Insulated – K .

We are now carrying 7 new economical servo motors including a high torque servo with 13.0 kg-cm , and 3 new continuous servos with different speed and torque. You can now control Phidgets using Ruby. Ruby is a dynamic, open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write.

Ken Shirriff's blog: A Multi-Protocol Infrared Remote Library for the Arduino
Note for Arduino 1.0 I haven't had time to update the library yet, but several helpful people have told me that to use the library with Arduino 1.0, you need to change Do you want to control your Arduino with an IR remote?
Another important improvement in the next Minibloq version is its capability to send text through the Serial port (it already sends numbers): Minibloq has been in use for several month in some schools, and we are working a lot with primary school teachers. So, based in the good experience with the DuinoBot.Kids , which features a small LED matrix display (with just 8x8 pixels), we decided to add something similar to emoticons to the terminal. This way, kids can send smiles, and other expressions through the serial port directly to the computer screen, since most Minibloq's supported boards do not have displays: We want to enhance this kind of friendly features in the future and soon will have news about the release...

Here is the package for a 'fixed up' ATmega328 bootloader . To program it you may need to change the Makefile's ISPTOOL , etc definitions. The commands are make adaboot328; make TARGET=adaboot328 isp328 (I couldn't get the default 'isp' target to work so I made a new one) This version has a few fixes: first it integrates the 'no-wait' and 'no-hang' fixes below. It also fixes the annoying "missing signature bytes" bug that freaks out avrdude when programming without the IDE.

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. The microcontroller on the board is programmed using the Arduino programming language (based on Wiring ) and the Arduino development environment (based on Processing ). Arduino projects can be stand-alone or they can communicate with software running on a computer (e.g.

Processing is an open source programming language and environment for people who want to create images, animations, and interactions. Initially developed to serve as a software sketchbook and to teach fundamentals of computer programming within a visual context, Processing also has evolved into a tool for generating finished professional work. Today, there are tens of thousands of students, artists, designers, researchers, and hobbyists who use Processing for learning, prototyping, and production.

This is the new Arduino Revision 3! It sports an updated USB controller chip (was an atmega8u, now an atmega16u), duplicated Analog 4 and 5 pins next to the AREF pin (for future shields) and an IOREF pin next to the reset button (to let shields know the I/O voltage of the pins.)
My friend Usman and I are collaborating long-distance on an Arduino project. He’s a software guy (by which I mean he’s a guy actually made of software. OK, not really, but almost) and doesn’t have time right now to get up to speed on hardware. So, I send him bits of hardware as needed. This is how we did the RFID iConveyor project.

The basic idea behind PWM implementation on 8051 is using timers and switching port pin high/low at defined intervals. As we have discussed in the introduction of PWM that by changing the T on time, we can vary the width of square wave keeping same time period of the square wave. We will be using 8051 Timer0 in Mode 0.

ShiftBrite is a high-brightness LED module containing red, green, and blue elements. It uses a simple clocked serial interface to receive a 10-bit brightness value for each color, resulting in over a billion possible colors. Each input is buffered and output on the other side of the module. This allows each ShiftBrite to repeat the signal to the next, allowing longer cable runs between elements without excessive loading of microcontroller I/O pins. ShiftBrite elements feature current control and automatic overtemperature control (an overheating channel driver will shut off until it has cooled). Each channel can also be adjusted with a separate current control register, for fine tuning of each LED if close brightness matching is necessary.
