How do you make a good cup of coffee while traveling home? Mix equal parts of your computer, Arduino, automatic coffee maker, Power Tail Switch and Twitter! In this Instructables, frenzy shows how to setup a Python interface between the Arduino and Twitter, connect the Power Tail Switch between Arduino Pin 13 and ground, and […]
Shieldlist.org is searchable database containing information about more than 200 Arduino shields. Every shield has its own page with short description, link to its homepage, licensing and source information as well as very useful diagram of used pins. more features are planned in the future. If you submit new shield you can get a Freetronics […]
Arduino: the Documentary has been released! This CC licensed movie features interviews with many Arduino enthusiasts, developers, and users.
When Jack the Vendicator’s laptop display malfunctioned, he thought all was lost. He developed a rescue strategy using an Arduino as a USB bridge between the laptop and a desktop PC. He plugged the Arduino into the laptop, and connected a USB serial converter from his desktop computer to the Arduino’s serial pins. In effect […]
We recently did a little demo to send data to an Arduino with a TCP/IP Shield (using ATC-1000M) from an Android device via Wifi. The Android phone in this demo uses Android Scripting Environment (ASE). It is available on Android Market for free. Videos and source code after the break.
High electromotive force/electromagnetic field (EMF) readings can cause interference with precision electronic equipment, and have even been associated with paranormal/spirit activity! DTN’s blog has an Arduino project designed to detect high EMF levels. It uses an Arduino mega with a 4 inch wire antenna on pin 31 and 16 LEDs for indicators. Source code is […]
Here is a three-part series by basbrun progressing from analyzing IR protocol to using Arduino’s to control X10 devices via IR: Part 1 -examining the IR protocol (the USB Infrared toy could be used in this step!) Part 2 -controlling LEDs with IR remote. Part 3-controlling X10 devices with IR remote.
FreakLabs has an interesting project designed to conduct sniffing of protocols that ride on top of 802.15.4 such as Zigbee and 6LoWPAN (IPv6 over 802.15.4). The project utilizes their FreakDuino platform which contains an Arduino integrated with a wireless radio. The tutorial assumes that Wireshark is installed on your computer, the Chibi or chibiArduino release […]
The OBDuino is an in-car real-time display of various information, like speed, RPM, instant fuel consumption or average trip fuel consumption as well as others PIDs supported by the car. It reads the data from the car’s OBD-II connector, interfacing it via a MC33290 chip to the Arduino which processes the CAN data and outputs […]
If you’ve got a Guitar Hero and have the urge to cheat here’s the circuit for you. Johnny Chung Lee at Procrastineering has developed a Teensy based circuit and program which analyzes the video stream from the game console to autonomously play the game. Via Hack a Day.
You may be familiar with Mitch Altman’s Brain Machine. A really trippy device that’s easy to build and program if you have a spare Attiny2313 and ISP programmer. Here HackDev has ported the code over to the Arduino!
Just in time for Christmas, Arduino 22 is now available! This latest release includes an SD card library, character manipulation macros and lots of other fixes and improvements.
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 […]
Here’s a project including code developed by Geek Cowboy that combines Arduino, RFID and the X10 controller library for home automation purposes.
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” […]
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).
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 […]
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 […]
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.
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.
