Slides from my talk at GlueCon '14 about programming an Arduino Due in Rust, and about using Rust for embedded or IoT applications.

Infrastructure for programming an Arduino Due in the Rust programming language. This includes a sample sketch that can be modified to do most any other sketch.

The BearDuino is a hardware-hacked Teddy Ruxpin—the infamous animatronic talking story-time teddy bear unleashed in all its uncanniness on the world in the 1980s—that has been turned into a kit for use with an Arduino microcontroller, ready for would-be makers to use for good or evil.

This post is based on the work made previously by tomek in wiring LCD displays using 4 bits. The basic idea is to group the 7 pins that are needed to drive the LCD in only 3 using a shift register. This is a cheap alternative to serial LCDs.

The three models (all of which we use here at Digital Diner) are the Arduino, Raspberry Pi and BeagleBone. We chose these three because they are all readily available, affordable, about the same size (just larger than 2″ x 3″) and can all be used for creating wonderful digital gadgets. Before we get to the comparison, here is a brief introduction to each one.

From the moment these LED displays made an appearance on our weekly Ask an Engineer show, comparisons were being made to the DeLorean time circuit from the Back to the Future films. It was a moral imperative then to make a demo! If you’re handy with Arduino and some shop tools, you should be able to pull off something similar (better, even), or adapt the ideas to other projects. This was quickly built in fun, so please don’t expect the same level of polish as a finished product tutorial.

Presenting the Dymaxion Auto-Matic Buckminster Fuller. It's a retro-futuristic black and white screen mounted into a 1950s (or so) radio chassis, which generates and displays text that American luminary R. Buckminster Fuller might have said if he were a piece of software.

Communicating with a host computer can allow a simple Arduino-based system to gain access to a wide variety of devices and information. Most people link an Arduino to a host using serial communications across a USB connection with custom code running on the host to send information to the Arduino or receive it in return, but giving your Arduino the ability to pretend to be a keyboard or mouse opens up a whole world of possibilities because it means your Arduino can interact with software that was never intended for external control. That could be desktop software such as a game or a web browser: your Arduino could "type" into a web form and submit it on your behalf, or act as a custom controller for a game!

Project log for developing USB expansion shield for Arduino and associated code.

If you are planning to build a stand-alone system where a small but full-featured keyboard is needed, this simple solution could be useful for you.

The ADK TinkerKit is a complete pack of 25 TinkerKit Modules, Arduino Mega ADK, Mega Sensor Shield, and necessary wires to kickstart your Android development experience without soldering.

This shield allows you to connect a HP C6602 inkjet cartridge to your Arduino turning it into a 96dpi print platform. It only uses 5 pins which can be jumper selected to avoid other shields. It is designed with a Arduino Mega footprint but fully supports both the Arduino and the Arduino Mega. It uses all through-hole components to make assembly easy even for beginners.

If we had to imagine our dream DIY project chances are it would involve Arduino, Twitter and, of course, cats. How we'd combine those things we're not sure, but we'll admit to being big fans of Samuel Cox's eSleeper, which turns a hollowed-out eMac into a bed for his feline. Inside the shell is an Arduino Ethernet connected to an IR sensor, some LEDs and a sound shield. When the cat breaks the infrared beam it triggers the iconic Mac chime and turns on a series color-shifting LEDs for a little mood lighting. From there the clock starts ticking. When little Fluffy (Captain Whiskers? Matlock? Penny? Greg?) decides she's had enough napping and leaves the white plastic cocoon, tripping the IR sensor again, a random phrase is tweeted, along with the length of the cat's siesta. Check out the video after the break to see the eSleeper in all its adorable DIY glory.

The μWave is a hack involving an Arduino and a TouchPad taped to a microwave door, which plays YouTube clips perfectly matched to your cooking time. This Frankenstein uses the Arduino to send data from the microwave's seven-segment displays to a web server, which finds a highly-rated YouTube video of the right length. The web client running in the browser treats you to a video clip that ends right when your food is done, then optionally tweets or sends a text message. The hack was created by students at the University of Pennsylvania, where it won first place in the PennApps Hackathon. There are no stated plans for commercialization, but the team will present the project to Google as part of the grand prize. If Mountain View announces a microwave any time soon, we'll know to expect great things.

Looking for another way to use that aging VGA CRT screen hogging space in the closet? Try making your own dedicated weather screen by mixing together Google's meteorological data stream and some Arduino magic. It looks like parsing that Google Weather data was a bit of a challenge on the miniscule 2KB of RAM, but a tinkerer going by the handle Zmashiah has managed to do it. He's even managed to cram in a few extra graphical flourishes, including icons and background themes that change depending on the temperature and time of day. The entirely PC-free device grabs the data through an Ethernet connection and flashes up all the weather goodness in stunning VGA. Any meteorological mavens reading this can grab the full shopping list and procedure at the Instructables link below.

Come this (Black) Friday, it'll officially be the season for gift-giving and general family dysfunction. So, why not warm that tech-tinkering heart while heating up the creative juices of the baby-bound set with a Freaklabs purchase that puts your money to good use? The outfit's got a monster mash FredBoard up for order that splices together an Arduino and breadboard to make your first brush with homegrown modding a relatively painless affair. Oh, and the proceeds are destined for a Mommy-centric hackerspace -- dubbed Mothership HackerMoms -- in San Francisco that does double duty as a day care for little leg-clingers and a lab for their electronics-inclined parents. These ladies-in-programming currently swap house hosting duties, but with the boost from your potential feel-good donations, could snag a proper venue of their own. Feel like getting in the holiday spirit early? Then click on the source below to bring some early cheer to Bay Area baby Mommas.

You’ll have three weeks (11/11-12/2) to come up with an idea, build it, submit your project to the Great Create and leave a link to your project in the comments below. We’ll go through and pick the project that uses Arduino in the most creative and innovative way – the chosen project will get a $500 RadioShack gift card – just imagine the awesome projects you could build with that!

Oftentimes makers will build MAME cabinets that resemble old-time arcade games, but ultimately they’re just PCs with buttons and joysticks wired in. With the Coffee Table MAME Console, we’re going to build a stripped-down version of the arcade machine. It doesn’t need a monitor because you can use your TV, and instead of having the computer inside the enclosure, the console connects to your PC via Bluetooth.

We’re super excited about our new issue, MAKE Volume 28, which just hit newsstands last week. The issue theme is Toys and Games, and naturally, our entire focus was on fun, from the playful 8-bit graphics style of the cover design by eBoy to the 176 pages of projects and profiles that give you ...

I finally got around to testing out the Arduino Ethernet shield I picked up many months ago.

[Chris] just posted his latest tutorial which shows you how to read position data from a resistive touchscreen. These devices are fairly simple, and since they’re used in a lot of consumer electronics you can pick one up for a few bucks. This looks like it is overstock for an old Palm device.

Inspired by the allegedly Windows Android x86 demo with a 23 inch multi-touch screen by Martin Drashkov (see second video below), I decided to give my own version a spin.

This is revision 2.0 of USB Host Shield. Thanks to new interface layout it is now compatible with more Arduinos – not only UNO and Duemilanove, but also big Mega and Mega 2560 work with Standard variant of this shield out of the box. No more SPI re-wiring and code modifications – just solder included stackable connectors (2×3 ICSP connector’s female side should be facing down), plug and play!

Want this.

This tutorial will show you how to solder together a shield for an LCD with a 8x2 header

TVout + Wii nunchuk = awesome

I wanted to start gardening, but I knew I wouldn’t keep up the regular schedule of watering the plants and making sure they got enough light. So I recruited a microprocessor and a suite of sensors to help with these tasks. An Arduino microcontroller runs my indoor garden, watering the plants only when they’re thirsty, turning on supplemental lights based on how much natural sunlight is received, and alerting me if the temperature drops below a plant-healthy level. For sensors, the Garduino uses an inexpensive photocell (light), thermistor (temperature), and a pair of galvanized nails (moisture).

The hardest part was converting HSB into RGB - the equations that I worked on from wikipedia are an absolute nightmare to translate into code (at least for me at this stage). I was about to give up when I saw this link, full of ready-made colour conversion functions: http://www.easyrgb.com/math.php?MATH=M21#text21.

Infrared remote library for Arduino: send and receive infrared signals with multiple protocols

IR detectors are little microchips with a photocell that are tuned to listen to infrared light. They are almost always used for remote control detection - every TV and DVD player has one of these in the front to listen for the IR signal from the clicker. Inside the remote control is a matching IR LED, which emits IR pulses to tell the TV to turn on, off or change channels. IR light is not visible to the human eye, which means it takes a little more work to test a setup.

Adding quality audio to an electronic project is surprisingly difficult. People tend to end up either using low-quality ISD chips (you might get 8Khz sampling rate for 30seconds out of these, if you're lucky!) or mucking around with trying to control a CD or MP3 player. Although it's possible to generate audio direct from a microcontroller using a PWM output, the quality is often low and its hard to fit a lot of music in an EEPROM chip. You can buy an embedded MP3 player board, but they're either expensive or difficult to use!
