Dirk has written an article detailing how to make a simple Arduino wireless shield using the TL-WR702N wifi router: There’s always the need for cheaper Arduino equipment and there’s always the need for wireless activities in your project. But an Arduino wireless shield costs much. Everyone of us has got an ethernet shield. They are […]

Minimal ECG using an Arduino and Xoscillo
Raul from Coding Laboratory has designed a DIY ECG project using an Arduino and Xoscillo: To display the wave I am using XOSCILLO, a very cool and open source tool (which I wrote :P) that converts your Arduino into an oscilloscope.
Seeedstudio BareDuino Nano — smallest Arduino yet
Seeedstudio has announced what may be the smallest Arduino compatible board yet. The BareDuino Nano was designed by 15 year old maker Niek Blankers from the Netherlands, and sports the same processing power as Arduino Uno in a 21×14 mm footprint and includes an FTDI programming interface and on-board voltage regulator. The board’s pin spacing […]
Andruino: A simple 2-way bluetooth-based Android controller for Arduino
TechBitar wrote this Instructable detailing his ANDRUINO, the 2-way Android controller for Arduino via bluetooth: ANDRUINO is a simple tool to help you control your Arduino (or clone) from your Android phone. It’s both an Android app and an Arduino program. Andruino has a simple Android user interface to 1) control Arduino’s digital and PWM […]
Tutorial – Arduino and the TI ADS1110 16-bit ADC
John Boxall over at Tronixstuff has a series of Arduino tutorials. This chapter fifty-three of a series will show you how to use the TI ADS1110 16-bit ADC with Arduino: Moving on from the last chapter where we explained an 8-bit ADC, in this instalment we have the Texas Instruments ADS1110 – an incredibly tiny […]
Augmented guitar uses Arduino & Max MSP
Here’s a video by Thebishopgame describing how his Guitarduino works, an Arduino/MaxMSP guitar mounted midi control system: There are 6 arcade buttons on the bridge, three force sensitive resistor squares on the body, and a long FSR strip on the back of the neck. The arduino just takes sensor readings and spits them out the […]
RAPIRO: The Humanoid robot kit for your Raspberry Pi
Here’s an interesting Kickstarter project the RAPIRO designed by Shota Ishiwatari. It’s designed to work with a Raspberry Pi and comes with a Arduino-compatible servo controller. Switch Science is one of the collaborators of this project: RAPIRO is a cute, affordable, and easy to assemble humanoid robot kit, which comes with 12 servos and an […]
Arduino Pong game
Pong is the classic video game, essentially the “Hello world” of gaming development. James Bruce, working at the parhaat uudet nettikasinot company, has developed a simple implementation of Pong for the Arduino which requires the addition of only an RCA jack, two 10K potentiometers, a pushbutton and a handful of resistors. The video output is […]
Arduino Uno 3 million samples per second logic analyzer
Bob Davis has built an Arduino powered three Million samples per second six channel logic analyzer: In the video below you can see what the live display looks like. He is using a 74 series decade counter to divide down a 10Mhz crystal so that he has some nice fast stuff to sample. He experimented […]
Digital light meter using Arduino and BH1750FVI sensor
Raj writes that he’s just finished new project a digital light meter using Arduino and BH1750 sensor. The meter can display light intensity in both Lux and Footcandles: A light meter is a device that measures the intensity of light. It finds applications in schools, hospitals, production areas, passageways and more to measure and maintain […]
Arduino waveform generator
Chris from PyroElectro constructed this waveform generator using an op-amp, resistor ladder, some trimpots and an Arduino. You can find all the information on how to make your own step-by-step with photos, schematic and code at PyroElectro. Via the contact form.
Open SmartWatch Project: Arduino tool chain (alpha)
We recently posted about the Sony Open SmartWatch project. Since then, Arduino enthusiasts and Sony have been working on a proof of concept for how SmartWatch could be setup to work in an Arduino environment. As a result of these efforts, the Arduino crew have published a GitHub project that includes an alpha version of […]
OpenSprinkler, an open-source internet-based sprinkler / irrigation timer
Ray has written a detailed article about his OpenSprinkler 2.0 Arduino-based irrigation controller: OpenSprinkler is an open-source Internet / Ethernet sprinkler timer / controller based on the Arduino platform. It works with standard 24VAC sprinkler valves commonly found in household watering and irrigation systems. You may be planning to buy or have already purchased a commercial […]
DigiX – The ultimate Arduino compatible board with WiFi
Ihsan informs us of Digitstump’s inexpensive, powerful Arduino-compatible board with WiFi – the DigiX: Have you seen this DigiX board by Digistump? They are the ones who created the Digisparks as well. As a difference from Digispark, this time they are aiming high end region of the devboards.
Autonomous car build
Jason Dorweiler blogged about his autonomous car build: For the localization of the car I’ll be using a GPS sensor and accelerometer. First, the GPS will find the starting coordinates of the car. Then the car will start moving, somewhat blindly at first. Once the car is moving, data from the accelerometer and elapsed time […]
How to ID your Arduino board
Which Arduino boards are commonly in use and how do you distinguish one from another? Alex Castle has posted a roundup of the most common Arduino boards on the market right now, with tips on how to distinguish between them based on processing capabilities, feature sets and form factor. This summary should be helpful to […]
PC-based heart rate monitor using Arduino and Easy Pulse sensor
Raj writes that he’s just finished a new PC-based heart rate monitor using Arduino and Easy Pulse sensor (see previous Easy Pulse post). This project takes the sensor’s analog photo-plethysmography (PPG) output and feeds it into an Arduino ADC channel which converts it into digital counts which are then transferred to the PC through a […]
