We first thought [Alexis Ospitia]’s watch was a sports watch made with an Arduino, but it’s actually a sporty watch made with an Arduino. This explains the watch’s strange ability to tell you the current temperature and humidity.

The core of the watch is an Arduino Mini. To make it good for time telling, a real-time clock module was added. A DHT11 monitors the temperature and humidity. A charge circuit and lithium battery provide power. Finally, the watch displays the date, time, and other data with an LCD from a Nokia 5110. We can tell you the last part that’s going to break on this.

Even if you think the watch is a bit chunky, the tutorial is very slick. [Alexis] has taken the trouble to individually draw and describe each portion of the watch’s construction. He explains each pin, what they do, and provides a Fritzing drawing of the wires to the Arduino. The code is provided; to program the watch a USB-to-serial module must be used.

For the housing he made a box from a thin gauge aluminum sheet and attached leather straps to the assembly. The final construction is cool looking in a techno-punk way, and is fairly compact. One might even say sporty.

Here we are today announcing the winner of this week for our Instagram giveaway!

Congratulations to Thinklab.ph from Manila (Philippines) for the following picture taken at Genuino Day with Rizal High School showcasing an Arduino based battle robot: Tagisang Robotics, Salamander.  They win a Genuino MKR1000 and a Genuino Mug!

Yes, you can win it too! Here’s how:

– Follow our official Arduino.cc account on Instagram

– Share your pics on your account on Instagram using hashtag #ArduinoD16 and #GenuinoD16 and mention us with the tag @Arduino.cc

– Every thursday, from April 7th to May 26th we are going to choose one of your pics (posted starting April 2nd) and announce on this blog a winner of an Arduino or a Genuino MKR1000 and one of our t-shirt or mug for a total of of 8 lucky people. Easy enough, right?

Remember to share cool pictures regarding Arduino and Genuino moments in your community also beyond Arduino and Genuino Day.
Show us your talent!

We’re very happy to announce that the source code of the real-time operating system (RTOS) powering the Arduino 101 and Genuino 101 is now available for hacking and study purposes.

The package  contains the complete BSP (Board Support Package) for the Curie processor on the 101. It allows you to compile and modify the core OS and the firmware to manage updates and the bootloader. (Be careful with this one since flashing the wrong bootloader could brick your board and require a JTAG programmer to unbrick it).

The firmware runs on the x86 chip inside the Curie module and communicates with the ARC core (which runs your Arduino sketches) using the callbacks.
Right now, the x86 core takes care of handling Bluetooth Low Energy (BLE) and USB communication, offloading the ARC core.
You can use the code which implements these functionalities as a starting point for your custom extra features.

Ever wondered about adding Mouse and Keyboard functionalities to your Arduino 101 and Genuino 101? Or uploading your sketches via BLE? Or add deep sleep functionalities when your application is battery powered? Now you can! (Some effort may be required )

We hope that this step will bring even more interesting features to your Arduino 101 and Genuino 101, so even if you are not into low-level C programming, keep an eye on the dedicated forum section and Arduino 101 core github repo to follow the news and be the first to try new features.

If you want to know more about projects made with Arduino 101, check our Project Hub section in Arduino Create, don’t forget to share with the community your experiments creating a new project and take look to this obstacle avoidance tutorial  on America’s Greatest Maker website  !

What do you do if even the smallest Arduino boards (or their clones) are too big for your homebrew project? If you're Johan Kanflo, you find a way to make them even smaller. His AAduino project turns the already miniscule Tiny328 Arduino clone into an even smaller computing device that's about as big as an AA battery. Through creative wiring, it even fits inside a typical battery holder and draws power from the batteries in the remaining slots. He had to underclock the processor to extend to the battery life, but it's otherwise as capable as its normal counterparts.

If you're playing for an audience you don't want to spend your set looking at a screen. See how one musician made this MIDI foot board for performances.
