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 […]

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 […]
Control microbes with your mind
Here’s a video by Geva describing how to control microbes with your mind: Paramecia will change their swimming direction in response to an electrical field. With an Ardunio, a hacked brain sensor and a little code you can control your own army of single celled minions with mind power alone. Full build instructions and source […]
AD75019 crosspoint analog switch
Paul over at Dorkbotpdx has written an article about his AD75019 crosspoint analog switch: The chip is controlled by a big 256 bit shift register. I just chained the 3 chips in tandem, so the shift register is 768 bits. In the regression tester, I used 3 of these chips to allow any combination of […]
Wireless monitoring
Brohogan presents this post explaining the process for building a solar powered wireless radiation monitor: This project measures the background radiation outside the house, and transmits it to a display station inside the house. The outside sensing unit is solar powered (but it doesn’t have to be), and should have a range of at least […]
Welcome Arduino Yún – the first member of a series of wifi products combining Arduino with Linux
Welcome Arduino Yún – the first member of a series of wifi products combining Arduino with Linux: Massimo Banzi announced it some minutes ago during his annual “The state of Arduino” presentation at Maker Faire Bay Area: Arduino Yún is the first of a revolutionary family of wifi products combining Arduino with Linux. Yún means […]
Arduino Workshop: A Hands-On Introduction with 65 Projects
Here’s an Arduino Workshop book by John Boxall of Tronixstuff, a hands-on introduction to Arduino with 65 projects: Although there are seemingly endless Arduino tutorials and articles on the Internet, Arduino Workshop offers a nicely edited and curated path for the beginner to learn from and have fun. It’s a hands-on introduction to Arduino with […]
WiFiDuino = WiFi + Arduino
TheHardwarer has designed this WiFiDuino, an Arduino board that has a WiFi module: WiFiDuino is a new Arduino board that has a WiFi module. The circuit is based on the famous open source “Arduino Micro” from Arduino and Adafruit. To add WiFi connection, the new module “CC3000” from TI is used.
ENC28J60 and Arduino
Luca wrote a short tutorial on how to develop a small website that gets data from Arduino: In this tutorial, I’m going to show how to develop a small website that gets data from Arduino (using your ethernet shield), stores it and displays it on a chart.
Rave shades: The self assemble LED glasses kit
Rave shades: The self assemble LED glasses kit These Rave Shade – LED Glasses look like a ton of fun. They are Arduino based and use 74HC595 shift registers to light all the LEDs. At first I though it was a silly design since with a PCB sitting on your face you would not be […]
Doomsday clock Arduino shield
Tully shared his Doomsday clock Arduino shield in the project log forum: Here I would like to log new innovations that can be done using the Doomsday Clock Arduino Shield. A recent innovation completed by Devin Sean McCullough, is a web-based graphical user interface that will write the code for you. This one is really fun […]
Lira, an Arduino-compatible microcontroller
Lira is an open source Arduino-compatible microcontroller designed by Lyratron: What I came up with is the Lira. It is, as you will see, little more than a breakout board for the ATmega328, but it provides all the bare necessities like voltage regulation, basic power conditioning and an FTDI programming interface. It’s the smallest, simplest, cheapest design […]
Dot Matrix wall writer – Time writer
Dot Matrix wall writer – Time writer: Olivier van Herpt invented a machine called the Time Writer. It allows any graffiti artist in training to get their message out to the masses with the push of a button. An Arduino controls the action here. The Arduino pulses a number of relays which open and close […]
Project-a-week: RickPAW Betty crocker Arduino
This week Rwinscot shared his Betty crocker Arduino in the project log forum: I’d love to get into Arduino… but I don’t know how to solder. Which got me thinking about using through-hole sockets on a PCB. As the title of this post… a Betty Crocker Arduino. Add your through-hole components, mix, and bake your ideas. […]
Clock four, a scrolling text clock
John Boxall over at Tronixstuff posted a step by step guide of his Clock four build: Next in my random clock collection is this model, which displays the time in words using a Freetronics DMD via an Arduino-compatible board.
Data from Arduino sent to the Net using an Android phone
This video by Kerimil demonstrates his method for sending data to the internet with an Arduino and Android phone. Via Hacked Gadgets.
Arduino and KTM-S1201 LCD modules
John Boxall over at Tronixstuff has a series of Arduino tutorials. This chapter forty-nine of a series will show you how to use KTM-S1201 LCD modules with an Arduino: After looking for some displays to use with another (!) clock, I came across some 12-digit numeric LCD displays. They aren’t anything flash, and don’t have […]
Another project-a-week: ATtiny85 programming shield
This week Rwinscot shared his RickPAW ATtiny85 programming shield project in the forum: Saw a couple implementations of the ATtiny85 programmer on Instructables… and decided to roll my own. It’s bare-bones, but gets the job done. It works as a minimal Arduino shield and has headers for ‘jacking-in’ to the uC. Goals on this one are […]
Nixie clock: 4 – the touch sensor
This video of Luca Dentella demonstrates the IQS127D touch sensor and an Arduino: My Nixie clock won’t have any visible buttons, so I chose to use a touch sensor, that signals to Arduino when the user touches the clock. I brought from SureElectronics the Capacitive Proximity and Touch Button Control module, based on the IQS127D […]
