Olivier writes: This command-line enables “Quick” Arduino prototyping without compilation. Reading analog values, dis-/enabling ports and even I2C register manipulations are done in seconds instead of minutes. I will shows you how to set the time of a “DS1207” I2C realtime clock as well as executing some basic operations. The impatients of you just download the […]

Arduino GPS distance calculator
GPS distance calculator created by a group of students from Indiana University, built as a final project: As sports fans building for golfers, we kept the design anchored to real courses in Indiana, where players care about precise yardage from tee to landing. The handheld logs latitude and longitude at impact and at rest, then […]
A small GPS Arduino watch/clock
Here’s Oscar Liang another Arduino GPS project, he writes: Garlow stands for GPS Arduino Rechargeable Logger OLED Watch. The device gives GPS information which is logged on SD card and shown on a OLED display. It can be carried as a watch or simply used as a GPS data logger. The whole system is based on Arduino […]
Digispark Pro – tiny, Arduino ready, USB and mobile dev board

The super small, dirt cheap, always open source, Arduino compatible, USB (and Mobile and Wireless!) development […]
Proto I/Os Arduino
Ricardo of Electropepper writes about their latest project: Now i want to show you my most recent project, an arduino shield aimed for prototyping, it has 8 LEDs, four buttons a buzzer and a temperature sensor, like everything else in my website its all open source, you can check the project here Via the contact form. […]
Creating a Spotify remote with an Arduino and LCD shield
Steven from Hackshed writes about their latest project. We have put together a Spotify remote using an Arduino and LCD Shield; it uses a .NET application as a controller and communicates with the Arduino to take input via push buttons and output to the LCD. Project details are available from Hackshed.co.uk.
Reverse engineer wireless temperature / humidity / rain sensors, part 1
Ray Wang writes: I just wrote a series of three posts about how I reverse engineered a few off-the-shelf wireless temperature, humidity sensors and rain gauge, and used an Arduino to listen to and decode the sensor data. The tools involved are quite simple: an Arduino and a 433MHz RF receiver. I also used a […]
miniLOG – Precision standalone voltage logger
Jakub Felcenloben over at Electronics Lab has written up documentation on his latest project called miniLOG, a basic data logger: miniLOG is a precise standalone voltage logger that save the data on a SD card. It has 4 basic analog channels: one has 12bit resolution for voltage measurements, two channels have 10bit resolution for voltage measurements and […]
DIY external serial monitor
ARPix wrote this Instructable detailing the build of his DIY external serial monitor: Sometimes I needed an external serial monitor like the Serial Monitor in the Arduino Editor, to see what is going on. So I made one. The first picture shows an example how could be it designed. For the ESM I used an Atmel Atmega328 […]
Arduino based auto trigger spray keeps cats at bay
Curiosity killed the cat, but this project only sprays them with water. Tinkernut posted this humorous project useful for animal control in the kitchen. It uses an Arduino/PIR combo to sense motion and activate the auto trigger on a Raid spray bottle (of course, after emptying and thoroughly cleaning the Raid bottle.) When strategically placed […]
Using touch screen as remote control
Bajdi wrote an article on using an Arduino Due with a 5inch touch screen and a wireless nRF24L01 transceiver as a remote control: One of the things I wanted to try out was using the touch screen as a remote control. I have a lot of cheap nRF24L01 modules so I soldered one to the adaptor […]
DIY Arduino bluetooth programming shield
Here’s a how-to on making a DIY Arduino Bluetooth programming shield by Joshua Newell: If you’ve ever wished you could program your Arduino without lugging a USB cable around, wanted to put an Arduino project somewhere out-of-reach but still be able to easily upload changes to it, thought about building a project that interfaces with an […]
A digital thermometer hygrometer with analog displays
Kerry Wong writes: In this post, I will show you yet another thermometer/hygrometer build. But instead of using an LCD or 7 segment display for the output, I decided to go retro, using two “needles” to display the temperature and humidity readings instead. And to make the project more fun, I did not use analog […]
March 29, 2014 is Arduino Day
March 29, 2014 marks the 10th anniversary of the Arduino and the team has marked the day for a worldwide celebration of Arduino’s first 10 years. “It’s 24 hours full of events – both official and independent, anywhere around the world – where people interested in Arduino can meet, share their experiences, and learn more.” […]
Arduino based ‘Etch A Sketch’ laser cutter
Martin Raynsford writes about his latest Arduino based project: We switched out the standard controller with an Arduino (just in time for Arduino day) and connected two rotary dials to directly manipulate the X and Y axis. As long as the laser only cuts while the axis are moving then we should avoid fires. We’ll […]
Arduino + NES controller = USB keyboard
Grouflon has written up a unique project using an Arduino and an NES controller. “This week I worked on little script/manipulation that turns an Arduino and a NES controller into a USB Keyboard. Maybe it can be of use to some of you, so feel free to grab the code on this github repo. This […]
Using REST with Arduino Yun
Boris Landoni from Open Electronics writes: With this short guide we release today, we will explain you how to use your Arduino Yun to do something that was never accomplished before with a board of such family. We’ll face a real embedded project, with its set of sensors and management and control applications. Thanks to […]
Fast PWM and electromagnetic interference
Marios Andreopoulos writes: A few days ago I wrote a blog post about Arduino and EMI. By using fast PWM and a plain breadboard wire, I was able to detect electromagnetic interference using a usb TV tuner, with its antenna near my circuit. Not only that, but by manipulating duty cycle to create a primitive […]
