Internet Troll sniffing rat
Mike sent in his first Arduino project, an internet troll sniffing rat: Sometimes we like to take a few minutes away from Hackaday to spend time with our families. But just when you take your eyes off of the incoming comments, Trolls are bound to strike. Well, [Caleb] and I found a solution to the […]
Arduino controlling X10
Here’s a project including code developed by Geek Cowboy that combines Arduino, RFID and the X10 controller library for home automation purposes.
HUGE wireless RGB LED display
siklosi saw the post about using a wifi router as an Arduino wireless serial connection, and shared his own take. This RGB LED wall is plays Winamp visualizations, and more. The LEDs are driven by Rainbowduinos, the Rainbowduinos are connected to the PC using the router as a wireless serial connection. I made this “little” […]
WiFi for Arduino with Asus WL-520gu
If you want to WiFi enable your Arduino but don’t want to spring for a shield, Todbot shows how to use the Asus WL-520gu router. By installing the DD-WRT Linux firmware the Asus acts as a serial-to-network gateway for Arduinos (or most any other USB device).
Arduino + MQ3 = alcohol breath tester
This the season for good cheer, and what can be more cheerful than a project that’s as much fun to use as it is to build? How about a homebrew alcohol breath tester? Daniel Andrade shows how to build just such a device using just an Arduino, MQ3 alcohol sensor and a handful of resistors […]
RFID Arduino punchclock
If your kids are RFID enabled, here’s a project to give you peace of mind: the Kid-e-log by tronixstuff. Using an Arduino, EEPROM, RFID reader, real time clock chip and LCD readout you can keep electronic tabs on the kids by having them clock in and out of the house with RFID cards. A comprehensive […]
Codebox: save Arduino sensor data to Google
Many are familiar with how to read data from Arduino into Processing. One such example varies the a PC’s onscreen graphics relative to the intensity of light on an LDR. Here MAKE presents a project which web enables Arduino sensor projects, allowing Processing data to be communicated and stored in a Google spreadsheet doc.
Plumbing: Parallel programming for the Arduino
Concurrency.cc has introduced Plumbing, a Creative Commons licensed introduction to programming the Arduino using the programming language occam-pi. The tools are open source and facilitate parallel processing within the Arduino. The most recent versions for Windows, Mac and Linux are available for download. Check our the free PDF book download.
AVR crypto library
The power of microcontrollers is limited relative to FPGAs. Nevertheless, Das-labor has developed a set of implementations of different cryptographic algorithms in C designed to function within the limited memory space of microcontrollers. Check out the Avr-Crypto Wiki.
Arduino on an FPGA
Talk about going full circle! Gadget Factory has coded an Arduino core into a Spartan 3E on the FPGA ButterFly platform. This expands your prototyping opportunities, and provides beginners with a familiar FPGA core to build on. Via Embedds.com
USB Hacking with the Arduino
Here Collin’s Lab at Makezine explores the use of microcontrollers as USB host controllers. Very instructive and worth a look by anyone wanting to learn more about USB and its integration with microcontrollers. Via Makezine
HOW-TO: ATC-1000M TCP/IP to UART Arduino shield
The goal of this tutorial is to use the ATC-1000M with the Arduino. Our ATC-1000M came integrated in a TCP/IP to serial shield. This shield can be used by an Arduino to connect to a LAN or wireless router.
Scratch4arduino
Scratch4arduino (S4A) is a graphical IDE based on Scratch from the MIT Media Lab. It’s designed to assist programming newbies in developing code for the Arduino board. With downloads for Windows, Mac and Linux (deb) this freeware program by Citilab currently works with the Duemilanove and Diecimila versions and includes modules for working with sensors, […]
Arduino/Processing based sonar
LuckyLarry has developed a sonar system based on the Arduino and an SRF-05 ultrasonic range finder. A servo sweeps the range finder across the target field, with the pingbacks processed and displayed on the desktop with Processing. Via Hackolog.
Arduino realtime audio spectrum analyzer
Paul Bishop has posted source code and the schematic for an audio spectrum analyzer based on the Atmega328/Arduino. The design takes input from a simple electret microphone, amplifies it through a transistor fed into the Arduino’s ADC input pin. The Arduino outputs video of a 64 band audio spectrum analyzer through two external resistors which […]
GNUduino: Arduino in gEDA
Following from the Arduino Shield in gEDA last week, Jeffery sent a full Arduino in gEDA. Meet the GNUduino: I have designed an Arduino using gEDA (GNUduino). All the files, making etc are available in the above page. Via the contact form.
Open source Arduino shield outline in gEDA
Eric writes: I’ve released an Arduino shield board outline in gEDA format under the Creative Commons Attribution 3.0 Unported license. These files can be used as a starting place for creating Arduino shield boards. Video overlay shield shown. Don’t forget there is also an Arduino shield outline in the Dangerous Prototypes Eagle parts library (CC-0). […]
MHVBoard Arduino clone with USB
The MHVBoard is an Arduino clone based on the Metaboard. It has a USB connection, but it doesn’t use an FT232R chip or a USB AVR. It uses the V-USB library to bitbang low-speed USB directly from the microcontroller. Via the contact form.
Arduino Uno quality control
Moogle was disappointed by his new Arduino Uno. He thought it was pretty unrefined: rough edges, thin solder mask, poorly aligned headers. Arduino responded directly that this is an isolated incident. They will replace any less than perfect hardware. (A Moogle followup post) Additionally, bongobat may have encountered a major bug in the circuit that […]
