SSD1308 OLED interface AVR library for Arduino/Teensy

Our forum regular Marcus posted a SSD1308 OLED interface library and pin connections to get you started with your Arduino/Teensy OLED projects. The display is a 0.96” 128 x 64 dot matrix that can be interfaced though both I2C or SPI interfaces, the library Marcus provides is SPI only and should allow you to get […]

Arduino & iPhone = GSR lie detector

Anna Dumitriu, Tom Keene and Alex May recently gave a presentation at 17th International Symposium on Electronic Art in Istanbul demonstrating how to build an Arduino to iPhone/Android interface with GSR sensor. A GSR sensor connects to an Arduino board. The Arduino generates an audio tone mapped to value of electrical resistance in the skin. […]

Atmel and Arduino Collaborate on AVR and ARM-based Development Platforms

Atmel and Arduino have announced a cooperative effort to produce three new AVR and ARM-based dev platforms debuting at the Atmel-sponsored Arduino Pavilion at Maker Faire located in Queens, New York, September 17 and 18, 2011. According to Atmel’s press release: Atmel and Arduino will be demonstrating several platforms in the Atmel-sponsored Arduino Pavilion including: […]

Arduino IDE hack speeds up code compile

Paul Stoffregen over at PJRC sent us a link to this video highlighting how to modify the Arduino IDE by editing the boards.txt file to allow the compiler to use precompiled files. This helps to speed up the overall compile and upload process. A cool enhancement originally developed for the Teensyduino board. Paul submitted this […]

Audioino: Arduino programmable via sound card

Here’s a unique way to program an Arduino chip: using your computer’s sound card! Chris from the hobby-roboter forum provides the details on this amazing hack in his forum post. The process simply requires the Atmega168 to be programmed with Chris’ special audio bootloader. The whole project requires only the addition of three resistors, two […]

Netduino vs Arduino

Greg Crawford at Citizen Scientists League has written a three-part series on the Netduino. In Part 1 he describes the Netduino’s features and compares this board to the more familiar Arduino. In Part 2, Greg details how to interface the Netduino with the SPI bus, and provides some C# code for this purpose. Part 3 […]

Arduino hack imitates Pixar’s living lamp, disses IKEA

This video shows “The Annoying IKEA LAMP” or SM-1, ArduinoArts’ finalist entry for SeeedStudio’s Grove Toy Kit contest: Headed by industrial engineer Javier Lander, the project weds two servos (one in the base and one in the lamp), sensors for motion and sound, a three axis accelerometer, LED light and audio board to an Arduino […]

RS-485 and Arduino

As seen in the above illustration from National Instruments, RS-485 ports are identical in appearance to RS-232 but with different pin assignments. You will not find them on contemporary home computer hardware, and they are only rarely seen on legacy machines. They are, however, found on various types of commercial computer and telecom equipment and […]

The Resistor JelTone: an edible toy piano

A group from  NYC Resistor (Ranjit Bhatnagar, Astrida Valigorsky, Mimi Hui and Catarina Mota) made an edible toy piano, called The Resistor JelTone, for the Jello Mold Competition. As part of our experiments we realized that jello and fruit, which contain a lot of water, are conductive. Embedded in each jello/fruit key is a sterling silver pin (food safe) connected to […]

InkShield: open Open source inkjet shield for Arduino

Nicholas C. Lewis is developing an interesting Kickstarter project known as the InkShield. This shield allows you to connect a HP C6602 inkjet cartridge to your Arduino turning it into a 96dpi print platform. It only uses 5 pins which can be jumper selected to avoid other shields. It is designed with a Arduino Mega […]

Pip-Boy 3000 game controller proto using Arduino

If you’re into the gaming scene, then you know that Fallout is a pretty popular post nuclear simulation game. A fan of the game wanted to create a prototype of the game’s wrist mounted controller known as the Pip-Boy 3000. MyMagicPudding writes: This is the first test of my attempt to build a working Pip-Boy […]

Serenading with Arduino

If you want to add a geek angle to a romantic dinner, what better way than Arduino generated music? Michele Spagnuolo has coded this project for a simple, minimalistic piano-theremin generated by Arduino and Processing. The hardware consists of a SRF05 ultrasonic sensor with Echo connected to digital pin 2 and Trigger/Init connected to pin […]

Arduino-based Tacit Project assists visually impaired

The Tacit Project from Grathio Labs is developing a wrist mounted sonar assistive device for the visually impaired. The hardware includes Parallax Ping ultrasonic sensors mounted in the glove which send distance measurements to an Arduino. The Arduino then activates small hobby servos to vibrate in the glove to communicate the relative distance to objects. […]

Enough Already: an Arduino based audio-b-gone for TV

Matt Richardson over at MAKE presents this cool solution to listening to the audio portion of the garbage overload known as entertainment news. He has design this project known as Enough Already which mutes the audio portion of a TV program when certain words are mentioned. The hardware consists of an Arduino and the Video […]

Arduino mindreading library

Chris from LVL1 Louisville’s Hackerspace has been working on hacking brainwave sensors using the Arduino. Both the Force Trainer and Mattel MindFlex use a daughterboard from NeuroSky that outputs serial data for values of ‘Wireless link’, ‘Attention’ and Meditation. Both of these devices have the same NeuroSky board, so the *easy* hacking instructions work for […]
