Arduino Cyclocomputer
Here’s a project which unifies art and tech: a LilyPad Cyclocomputer. Mark Fickett designed this bicycle computer which uses a magnet and reed switch as a cyclocomputer wheel sensor. This sensor is read by the Arduino/LilyPad (Atmega328) which processes the data and stores two trip meters and a speed histogram; the trip meters are reported […]
Modkit beta released
The first public beta of Modkit, an in-browser graphical programming environment for microcontrollers, has been released. Modkit allows you to program Arduino and Arduino compatible hardware using simple graphical blocks and/or traditional text code. Modkit’s graphical blocks are heavily inspired by the Scratch programming environment developed by the Lifelong Kindergarten Group at the MIT Media […]
DOTKLOK: Arduino based digital clock
DOTKLOK by Andrew O’Malley is an open-source, hackable, Arduino-based digital clock that displays a series of unique time-telling animations. The passing of time is depicted with numbers and abstract/geometric patterns, including animations inspired by classic video games such as Pong, Tetris, Pacman, and Space Invaders. An optional “random mode” changes the animation each day at […]
Free Oreilly workshop – Processing and Arduino in Tandem: Build a Mixer
Oreilly is offering a special follow-up to their earlier Processing and Arduino course. “Processing and Arduino in Tandem: Build a Mixer” will be presented free online by Instructor Joseph Gray on two successive Fridays. The course makes use of the projBox, a control box with installed potentiometers, switches and LEDs, which interfaces with the Arduino […]
QP state machine framework for Arduino
Quantum Leaps has released his QP state machine framework for Arduino. He says: QP is a lightweight, open source, state machine framework for microcontrollers such as Arduino. QP enables you to build well-structured and power-efficient event-driven programs as systems of concurrently executing state machines (UML statecharts). You can think of QP as a modern real-time […]
Arduino and TFT LCD tutorial
LCD displays of the 2×16 variety are a good way of getting feedback from your Arduino project. If you want a more enhanced visual experience, a thin-film transistor (TFT) LCD is the superior way to go. This tutorial by Tronixstuff describes a way use the the 4D Systems 1.44″ TFT serial interface LCD with Arduino. […]
Tiny Femtoduino: smallest Arduino
Fabio Varesano has designed what is probably the smallest Arduino compatible board. He states: By using the QFN32 version of the ATMEGA 328p, 0.05″ connectors, 0402 components and removing everything not strictly necessary, I’ve been able to design and hand build an Arduino compatible board which is very small (20.7×15.2 mm) and ultra light (2g) […]
Arduino magnetic levitation project
mekonik has published complete details on his Arduino magnetic levitation project. Not content to settle for a typical “hello world” LED blinker as his first project, he supplemented the Arduino with an electromagnet, Honeywell SS19 Hall effect sensor, MC3401P op amp, NPN transistor and 1N4001 rectifier. The circuit essentially uses the small Hall effect sensor […]
Using watchdog timers in your AVR projects
Here’s an interesting tutorial from Embedds covering the use of watchdog timers in AVR and Arduino projects.
Brain wave monitor with Arduino + Processing
Frontier Nerds have been experimenting with brain wave tech as part of their Mental Block project. In this well documented project they take the headset from Mattel’s Mind Flex game and hack it to communicate with an Arduino board to measure brain waves and display their levels graphically on a PC via Processing. They chose […]
Capacity tester for rechargeable batteries
BrianH has posted a useful Instructables project that tests the capacity of rechargeable NiMh and NiCd batteries. The circuit is based on an Atmega168, and functions by draining the AA batteries (from 1 to 3 batteries) then computes and reports the capacity in mAh. It uses a Nokia 5510 graphic LCD to report battery condition […]
Wireless Arduino message board
Uhclem has posted a wireless Arduino message board project on Instructables. The heart of the project is the Arduino with the Atmega328 interfaced with a Sparkfun Series I Xbee module, serial EEPROM and LDR. The display is an a LCD-compatible Noritake CU2009ECPB-W1J VFD character display compatible with the LiquidCrystal library. The purpose of this project […]
Measure liquid flow rate with Arduino
The Makers Workbench shares this project which measures the rate of liquid flow using a Seeedstudio Water Flow Sensor and Seeeduino. This is part of their Arduino Controlled PC Liquid Cooling project. The flow sensor uses a simple rotating wheel that pulses a hall effect sensor. By reading these pulses the Arduino mathematically calculates the […]
OpenMT: Open source Multi Touch
Open source Multi Touch, known as OpenMT, is an open source hardware project for developing multitouch applications. Unlike camera-based multitouch, OpenMT lets you make a thin, flexible multitouch surface. It is Arduino friendly and has been developed by Sensible UI in Seoul, Korea. Users can experiment with hardware development themselves with projects such as ArduMT, […]
PinguinoM: Arduino Network Monitor
This project by Paul Ameson utilizes the Arduino and BlinkM to monitor the status of your PC’s internet connection. This project, known as the PinguinoM, communicates via USB with a PC running a Python script. The Arduino board is loaded with the Communicator sketch from ThingM and changes the BlinkM according to the status communicated […]
Laptop touchpad interfaced with Arduino
Here’s an interesting article showing how to interface a common laptop touchpad with an Arduino. Metku’s project connects the Data, Clock, +5 V and ground connections on the touchpad to Arduino Pins 5 and 6, and power connections. Sample code is included, and the Arduino/Wiring library provides the necessary codehooks. In the video they demonstrate […]
Processing and Arduino in Tandem: Video Mixer and Audio Visualizer
Oreilly is making available a free online course dealing with Processing and Arduino combined to produce a video mixer/audio visualizer. Led by instructor Joseph Gray, the course takes place Fridays @ 10am PT February 25 & March 11, 2011. Each session is 120 minutes. You may view the course live online for free; thereafter, to […]
