Rolling MCUs, connectivity, security and software into one wearable package


This Android-based, Bluetooth-enabled wearable badge can act as a compass, watch, slideshow app, battery gauge and more.


Did you know that 45.7 million wearable devices are expected to ship this year, up 133.4% from the 19.6 million units shipped in 2014? And by 2019, reports are calling for shipment volumes to reach 126.1 million units, resulting in a five-year CAGR of 45.1. Given this emergence of body-adorned technology, the need for a hardware and software-based turnkey solution has never been so paramount. With this in mind, Atmel has unveiled the first-ever wearable solution that integrates its broad solutions offering all rolled into one.

Just in time for Computex 2015, the company has designed a 7cm x 9cm demonstrator around a smart badge concept, which combines low-power embedded processing, wireless, touch and sensor technologies to form an unparalleled turnkey system for virtually any type of wearable application.

This demonstrator converges hardware and software technologies, from Atmel and its partners, into a highly optimized and comprehensive out-of-the-box solution that addresses the complex requirements for the burgeoning wearable market, all while bringing their designs quickly to market. Users can wear it around their neck and display different applications (compass, watch, spirit level, slide show, battery gauge) specialized for the Andriod operating system (OS) and made by Adeneo Embedded.

“Adeneo Embedded has a long standing partnership with Atmel on Linux, Windows Embedded and more recently Android porting activities for AT91SAM ARM based MPUs,” said Yannick Chammings, Adeneo Embedded CEO. “With the collaboration on the Smart Badge concept, implementing Android-based wearable scenarios, Adeneo Embedded will scale OS and SW support to OEMs developing smart, connected, wearable devices.”

Based on Atmel’s embedded connectivity, the demonstrator can interact with other Android mobile phones. The badge uses a 3.5-inch display from Precision Design Associates and embeds MEMS and sensor technology from Bosch Sensortec, as well as memory multi-chip package from Micron combining 4Gb of LPDDR2 + 4GB of eMMC in a single package demonstrator running on the Android KitKat OS. Beyond that, Atmel is also developing a software framework that will allow various software partners to plug in their software and seamlessly work together.

With the anticipated growth of the wearable space, designers are continually seeking solutions that combine all the necessary and complex technologies into a simple, ready-to-use solution, enabling designers to focus on differentiating their products. The Smart Badge is the first demonstrator to bring together the company’s ultra-low power Atmel | SMART SAMA5D31 MPU, the Atmel | SMART SAM G54 sensor hub solution, a maXTouch mXT112S controller and a SmartConnect WILC3000 Wi-Fi/Bluetooth integrated solution.

“Atmel possesses the most complete, lowest power technology portfolio for wearable devices worldwide,” explains Vince Murdica, who is responsible for Atmel’s sensor-centric business unit. “Atmel’s Smart Badge is the first of many wearable reference designs and platforms to come as we want to ensure when customers think wearables, they think Atmel. We are very focused and excited to help accelerate the growth of the wearable market with turnkey, low power, complete hardware and software solutions.”

The Atmel powered DrinkMate has your BAC

Developed by the team at Edge Tech Labs, DrinkMate is a lipstick-sized breathalyzer that plugs directly into your smartphone. The project recently completed a successful Kickstarter campaign having exceeded its original $40,000 goal by nearly $60,000.

Unlike others of the past, the world’s smallest breathalyzer — which measures 1.8″ long x 0.62″ in diameter — works in conjunction with the Android phone’s app and displays his or her blood alcohol content (BAC) results instantly with no calibration, no mouthpiece and no battery.

How does it work? One end of the DrinkMate simply plugs into the phone’s microUSB port; a user blows into the other end; BAC results are then displayed instantly. However, keep in mind that like with any breathalyzer, users can’t eat or drink anything for 15-20 minutes prior to using the device in order to get an accurate reading.

“DrinkMate was designed entirely from scratch. We knew that to make a new breakthrough in size reduction, we couldn’t have any bias from existing larger designs,” a company rep noted on its site.

According to the National Highway Traffic Safety Administration, 33,561 people died in traffic crashes in 2012 in the U.S. alone with an estimated 10,322 as a result of drunk driving, accounting for nearly one-third of all traffic deaths that year. With its latest innovation, DrinkMate hopes to heavily reduce the number of drunk driving incidents and corresponding fatalities.

Combining Android and Arduino to control your TV

Couch potatoes, you’ll love this. Maker Jayvis Vineet Gonsalves has created a device ideal for any lazy Sunday spent on the sofa. His Android-powered TV remote allows for voice recognition software to control your TV with little to no effort.

This Maker’s Aergia (named after the Greek goddess of sloth) concept was devised for a situation where “the TV remote which is located just beyond your arm’s length seems to be many miles away and you do not have the energy, nor the will power to reach for it.” Hoping to utilize the power of his Android phone, which is never out of arm’s reach, Jayvis embarked on this project.

After preparing the plastic project enclosure and securing the power supply circuit, Jayvis turned to the brains of the device. To solve his lethargy issue, he paired a Bluetooth transceiver with an Arduino Uno (ATmega328).

“The Bluetooth Module enables the Arduino to connect and communicate wirelessly with the Android phone,’ the Maker noted. He also suggests that you purchase a Bluetooth Module, which is soldered to a breakout board, as purchasing only the Bluetooth Module without the breakout board means that “you will have to do the tricky soldering part which could damage the module if it is not done with the right tools”

Next, he attached an IR LED Stem to communicate with the TV and assembled all of the components into a final build. To control this device, Jayvis developed an Android app companion that functions as a universal Bluetooth remote. He notes, “In addition to all the basic buttons an IR Remote has, the app also features a voice recognition system and 12 user programmable buttons.” Perfect for any couch potato!

iPod hacking with Android and Arduino



A Maker with the handle “Erroneous Data” has posted a detailed Instructables explaining how to hack an old iPod using an Atmel-based Arduino Uno (ATmega328 MCU) and Android. Oh, and yes. There is no need to break out the soldering gun for this project.

“Just leave [your] old iPod plugged into the stereo and your music will start to play when you walk in the door. The Arduino acts as a liaison between the iPod and your Droid,” Erroneous Data explained.

“Since the iPod device is connected directly to your stereo, it eliminates any error that can occur when streaming the music to a separate device.”

Key features include:

  • Auto connect
  • Auto play
  • Auto pause
  • In-call pause
  • Alarm

As HackADay’s Brian Benchoff reports, with the right resistance on a specific pin on the 30-pin dock connector, iPods will send the track name and playlists over a serial connection, all while responding to play, pause, skip and volume commands.

“There hasn’t been much work towards implementing the copious amount of documentation of this iPod accessory mode in small microcontroller projects. [However], with a little bit of work, [he] managed to replicate the usual iPod dock commands with an Arduino,” said Benchoff.

“Using an HC-05 Bluetooth module, it’s possible to get this iPod-connected Arduino to relay data to and from an Android device with a small app. The circuit is simple, the app is free, and if you have an iPod with an old battery or cracked screen, it can still work as a music storage device.”

BlueMatrix: An Arduino-based LED matrix display

Designed by Dentella LucaBlueMatrix can be controlled remotely via a PC, smartphone or tablet.

Key project components include:

  • An Atmel-based Arduino Uno (ATmega328 MCU)
  • 
LED matrix display based on the HC1632C controller
  • 
Lipo Rider
  • 
Lipo Fuel Gauge
  • 
HC-05 Bluetooth module
  • 5mm plexiglas enclosure

The modules are connected as follows:

“The Arduino Uno is the heart of the project, [as] it manages the display, checks the battery status and talks (using a simple protocol) with the controlling device (Windows application or Android app),” Luca explained in a recent blog post.

“The BlueMatrix is powered by a Li-po battery (1 cell). The battery’s state of charge is monitored by Lipo Fuel Gauge, which sends the actual SoC (State of Charge) value to Arduino via I2C bus. The Lipo Rider module rises the battery voltage to 5V to power all the other modules and allows it to recharge the battery using a simple, mini-USB power supply.”

Meanwhile, the HC-05 module is tasked with managing Bluetooth connectivity.

“After having established the connection with the remote device, it transparently transport the data received/transmitted by Arduino via serial connection,” said Luca.

On the software side, Luca developed two applications to control BlueMatrix: a .Net application (developed in C#) and an Android app.

“BlueMatrix was designed to be portable, therefore I suppose that it will be mostly controlled using a smartphone; this is the reason why the Android app is better designed than the desktop one and it’s also available on Google’s Play Store,” he added.
