Arduino sinewave generator
labIII, the Laboratory for Experimental Computer Science at the Academy of Media Arts Cologne, posted this tutorial on how to generate sine waves with an Arduino using the Direct Digital Synthesis method. They explain: Here we describe how to generate sine waves with an Arduino board in a very accurate way. Almost no additional hardware […]
VirtualBreadboard 4.3.3
VirtualBreadboard 4.3.3 is a Windows GUI program that lets you simulate and develop embedded applications that use microcontrollers. It essentially lets you assemble virtual components on screen and auto generate code. Currently some Microchip PIC16 and 18 devices are supported, as well as Arduino. In addition a wide variety of simulated components such as LCD’s, […]
Arduino controlled light bulb PCR machine
Here’s an example of the Arduino being put into practical service. Russell Durrett is a Research Specialist in Bioinformatics and Genetic Engineering and is a cofounder of GenSpace NYC, the world’s first community biology lab. He was looking for a way to develop an inexpensive PCR machine, a costly thermal cycler used in DNA lab […]
Converting an Arduino to 3.3V
When Arduino debuted, most sensors and other interfacing devices ran on 5 volts. Nowadays Xbee radios, accelerometers and other new devices run on 3.3 volts. Here’s a short tutorial from Adafruit showing how to hack your 5 volt Arduino board to run on 3.3 volts. It’s a simple procedure involving replacing the voltage regulator and […]
Mouser now sells the Arduino
Chris writes: I noticed that Mouser now sells the Arduino! I am not a big fan of them, but it is great to see how far this little board has gone. They have a wide variety from the Lilypad, Uno, and Mega to lots of shields. Via the contact form.
Radiation sensor board for Arduino
David writes: We are very glad to announce we have just uploaded all the information of the Radiation Sensor Board The main finality of the Radiation Sensor Board for Arduino is to help people in Japan to measure the levels of radiation in their everyday life after the unfortunate earthquake and tsunami struck Japan in […]
Reversible motor control for Arduino and other MCUs
Nothinglabs has posted their circuit for a simple reversible motor control for use with the Arduino and other MCUs. The circuit uses two TIP120 Darlington Transistors, two 220 ohm resistors and a 12 volt DPDT relay, parts easily obtainable at any Radio Shack. This design supports PWM for variable speed control, handles loads up to […]
Arduino lightpen 1.0
Paul Bishop has developed a simple light pen input device for use with the Arduino (Atmega328). The hardware consists of a CDS photocell connected between +5 volts and Analog 0, and the code uses the TVout library for video output through several resistors to an RCA plug. To increase the pen’s sensitivity or adjust response, […]
Arduino: more LUFA hacks
LUFA (Lightweight USB Framework for AVRs) is an open-source complete USB stack for the USB-enabled Atmel AT90USBxxxx and ATMEGAxxUx AVR microcontroller series, released under the MIT License. Darran from Arduino Hacking has released the source, hex files, and sample sketches for his Arduino LUFA hacks for Keyboard HID, Mouse HID, and USB MIDI drivers for […]
MIDI over USB using Arduino Uno
krishi shows how-to use the Arduino as an HID MIDI device. Via the contact form.
JeeLabs JeeNode combines Arduino, RF
JeeLabs has a product known as the JeeNode v5, which is essentially a miniature Arduino (Atmega328p) board with an onboard RFM12B wireless module. Boards are available with the serial interface (shown above) as well as USB. You can buy the kit directly from JeeLabs, or build your own using the schematic and documentation provided. While […]
Arduino Dynamic DNS updater
Boris shared his Arduino DDNS (Dynamic DNS): …This device captures the IP address of your network and it publish on site DynDNS.com. All without PC. It allow a remote access to your LAN even if the IP address of the connections changes. If you don’t want to use the software provided by DynDNS, and then […]
Android / Arduino controlled remote wall socket
Mario Böhmer has informed us of his latest project, an Android/Arduino controlled wall socket. Mario writes: To show the basic principal I used a remote wall socket which normally is switched with a remote via a radio frequency of 433 MHz. What I wanted was to have an Arduino controlling the remote switch to turn […]
Advanced Arduino hacking
Maik Schmidt likes the Arduino, but like many of us he realizes the platform’s potential for advanced techniques beyond the IDE. In this article from the Pragmatic Bookshelf, he highlights the steps a beginner can take to learn how to develop software for the Arduino in a deeper way. Starting with how the IDE turns […]
qrpTracker: Arduino satellite tracker
VE9QRP has developed qrpTracker, a satellite tracking program that works on the Arduino platform. Based on the Plan-13 algorithm of James Miller, it can provide real-time satellite location and azimuth / elevation data and doppler shift tuning for up to fifteen satellites using a single ATMega328. With a small additional EEPROM, dozens of satellites can […]
iPad/Kinect/HTML5 controlled toy car
Gaurav Manek likes to work with Arduino and experiment with different means of remote control. His latest project involves several new technologies relating to gesture- and web-based control. He writes: This project extends a simple remote-controlled car, allowing it to be controlled by an iPad or by hand gestures. This project builds on the Arduino […]
More MAX3421E USB peripheral/host controller shields
Circuits@Home has two Arduino USB Peripheral/Host Controller shields with the MAX3421E we covered earlier. A driver is available for the Arduino, which should be portable to other microcontrollers. There are also libraries for working with USB devices, such as cameras, bluetooth devices, and simple Human Interface Devices like mice and keyboards.
Arduino-Lite: lightweight AVR library
The RoboPeak Project has developed a lightweight AVR library known as Arduino-Lite. The code is a lightweight high-performance firmware library for AVR MCUs developed based on the original Arduino project. In addition to the usual Atmega8, 168, 328 and 1280, it also supports the Attiny2313, Attiny26, Atmega48 and Atmega88. Its developers claim that compared to […]
