Processing + Arduino + touchOSC
Adrianmb from Make-a-tronik has written a tutorial on how to how to communicate between your mobile device (Android / iOS device) or a PC and Arduino through a protocol known as OSC (Open Sound Control). The project uses Processing, Arduino, and an LED RGB device. TouchOSC must be installed on the computer or iDevice you […]
iOS communicating with Arduino demonstration
This video from OSCON, the Open Source Convention, features Alasdair Allen demonstrating the use of Maker Shed’s RedPark Breakout Pack for Arduino and iOS. This demo the Redpark Serial Cable for iOS, which is an Apple-approved cable for connecting your iOS device to almost anything using serial communication. For more information and a link to […]
Simple MCU speaker boost
Bryan Duxbury offers a tip to get more volume from a weak MCU output pin. This may be an obvious trick to some, but I just did a short writeup on a really simple way to get more volume out of a speaker attached directly to a weak microcontroller pin – like those on the […]
Measuring temperature with Duinomite and KTY81
Olimex has posted this project for measuring temperature in range -55+150C for a solar water heater system. It uses the KTY81/110, a low cost PTC thermistor from NXP. The MCU board is the Duinomite we features in a previous post. Via the contact form.
Arduino-controlled espresso machine
Gleb Polyakov and Igor Zamlinsky of Atlanta, GA have designed this proportional-integral-derivative (PID) controlled espresso machine. Based upon their observations after reverse engineering a number of espresso units, the pair worked on developing a machine which would be reasonably priced, open source, be espresso pod compatible and have a PID controller. Temperature and pressure are […]
DuinoMite: MaxiMite-compatible BASIC computer
Olimex has introduced the Duinomite line of dev boards. DuinoMite is a MaxiMite Compatible Basic computer, originally designed by Geoff Graham, with additional features and Arduino shield-like layout. DuinoMite allows you to program in the BASIC language and have VGA and Keyboard interface, so you can develop and write your code in Basic without the […]
Apps for Arduino
Apps For Arduino is a website that specializes in creating software applications that work specifically with your hardware projects. You download and install the app on your Mac or iOS device and it communicates with the Arduino via a serial connection. While not all the apps are free, those which aren’t can be “purchased” as […]
TiDiGino, the Arduino-based GSM remote control
Boris writes about a new open source Arduino-based GSM remote control module, the TiDiGino: Using an ATmega 2560 and therefore the heart of Arduino, we have developed a universal remote control with GSM. This allows to control 2IN/2OUT, DTMF key, gate control and GSM thermostat activated remotely. The remote control very simple to use, thanks […]
Lower Webduino server overhead with a favicon.ico
Martin Lormes recently acquired an Arduino and Ethernet shield. Once he got the setup running on the web using the Webduino Arduino web server library, he checked the traffic using Wireshark and noticed that if the embedded server didn’t offer up a favicon.ico file when initially requested the browser would keep requesting the file. This […]
DIY iPhone remote automotive ignition
Will O’Brien developed this project allowing him to remotely start his car via an SMS sent to a jailbroken iPhone. The additional hardware involved is an Arduino, iPhone breakout board such as the PodBreakout Mini, 4x 10k resistors, 1x TIP120 and a 5 volt switching supply cell charger. All the details, including source code and […]
Connecting Arduino to Mathematica on Mac OS X
Mathematica is a comprehensive computational platform that purports to automate workflow involving computing results, “from building a hedge fund trading website or publishing interactive engineering textbooks to developing embedded image recognition algorithms or teaching calculus.” (It’s not open source, but a hobbyist license is available.) William J. Turkel teaches a course on interactive exhibit design […]
Tutorial: play simple Arduino audio samples
David Mellis from the Arduino crew presents this tutorial on playing short audio samples using only the Arduino and a simple speaker. Using the PCM Library for Arduino, this project takes a short (4 second) audio sample of your choosing which you encode on your PC into MP3 format (down sampled to 8 KHz, 8-bit […]
MetroChange lets you donate leftover MetroCard balance to charity
Students at NYU are developing a project to allow users of New York City’s MetroCard magnetic transit cards to donate leftover funds to charity directly from the card. It’s known as the MetroChange project and uses commonly available hardware, including an Arduino and mag stripe reader. The group really took a serious approach to development, […]
Coobro Geo Kit: open source Arduino/GPS project
Tyler of coobrolabs writes about his latest open source project, The Coobro Geo is an Arduino compatible through-hole GPS kit that allows you to navigate using only LEDs for direction and distance. It is built around the awesome Fastrax UP501 GPS module (MediaTek MM3318 chip). It is completely open source, so all design files and […]
Mini Thermal Printer from Adafruit
If you need a hardcopy compact printer for your next MCU project, check out Adafruit’s Mini Thermal Receipt Printer Starter Pack. This device takes TTL serial data at 19200 baud and prints out data and images. The starter pack lists for $61.95 and includes 50′ of thermal printer paper, a 5V 2A power supply and […]
Christmas Tree email alert
Matt Richardson from MAKE presents his take on the traditional CHristmas tree email notifier utilizing the Arduino and the Ethernet Shield. He says: “On a set interval, the Arduino will connect to a PHP-enabled web server which will, in turn, check for new email. The PHP web server will return the count of messages to […]
Vinciduino: an open hardware Arduino Leonardo clone
alb calls our attention to the Vinciduino open hardware project. “Vinciduino is a free open platform developed by members of the Spanish arduino forum. The board has been developed to be compatible with Arduino boards and has the same form factor of the Arduino Pro from Sparkfun. The main difference is that it supports the […]
MacLight: ambient Arduino lighting for the Mac
Adam Howard of 3 Sided Cube has developed the MacLight project. It works to vary the color of LEDs mounted behind your Mac to the average color of your monitor. It can also manually set the lighting via an RGB color selector. Adam says: Most projects I start are because it’s something that I want […]
Leonard Pirate, an Arduino Leonardo and Bus Pirate clone
Yoshi designed a Arduino Leonardo clone called the Leonard Pirate. It uses an ATmega32U4 with hardware USB peripheral. 6 analog and 18 digital pins broken out to headers. The board is designed with 2 choices of USB connectors. Use a USB A-type male connector that plugs directly into the USB port, or a mini-B female […]
