You may think that visually sensing colors is a complicated operation, requiring a camera or other advanced sensors. This isn’t always the case, as engineer “Tech Martian” illustrates in the video below, using a photoresistor and RGB LED along with an Arduino 101 board.
His setup uses the LED to shine on a piece of paper in three colors, measuring the reflected light intensity. These reflections are first calibrated by reflecting light off of white and black paper, which can then be combined to show the colors presented in front of the emitter/sensor pair. (more…)
Using the Arduino 101’s built-in Bluetooth capability, Bob from the I Like to Make Stuff YouTube channel has crafted a beautiful, smartphone-controlled scoreboard.
If you’re into competitive sports, or perhaps want to settle who takes the trash out the most once and for all, an RGB scoreboard is a great solution. Perhaps it’s overkill in some cases, but Bob’s creation, which he expertly makes in the video here out of MDF looks amazing, and is large enough to be seen from a distance. It’s also small enough to be nominally portable.
His setup employs an RGB LED unit for each of the pixels that make up the score display, and uses an Arduino 101 as the brains of the device. Control is accomplished via a mobile app. (more…)
Just days after celebrating the Arduino 101‘s first birthday at Maker Faire Rome, we’ve partnered with Hackster, Intel, and Seeed Studio to launch an exciting new contest. We’re challenging you to unleash the powers of the Intel® Curie™ Module-based board and “Invent Your Future.”
Perhaps you want to build an autonomous boat for collecting ocean pollution data, or a pair of shoes that play different sounds for different exercises, or maybe even a wireless gesture-based home automation controller? Whatever you choose, we want to see how you use the Arduino 101 as the brains behind your next creation.
For those who may not be familiar with the 101, the board combines the performance and low-power consumption of the Intel® Curie™ Module with the simplicity of Arduino. It keeps the same robust form factor and peripheral list as the Uno with the addition of Bluetooth LE capabilities and a six-axis accelerometer/gyro to help you easily expand your creativity into the connected world.
Like the rest of humanity, Arduino Sweden’s interaction designer Marcus Johansson has been glued to the Pokémon GO app. However, as fun as flicking a digital ball with his finger to catch ‘em all may be, he wanted something a bit more realistic. Enter the Arduino Pokéball.
Based off an Arduino CTC project, an Arduino 101 placed inside some protective MDF casing allows him to physically throw the ball, which is then mimicked within the game. It uses the 101’s IMU and Bluetooth track the toss and then send it to the phone.
UPDATE: For those who may’ve thought the video above was fake,you’re in luck. Johansson has updated his project along with a step-by-step tutorial so you can build your own. Since the original casing was damaged during testing, a colleague helped 3D-print the new exterior of the Pokéball to house the Arduino and power supply.
The brainchild of Tomás de Camino Beck, Polymath Boxes are experimental sound boxes. Using a Genuino Uno and 101 along with some 3D printing, these units enable young Makers and adults to experiment with programming and math to produce noises and tunes, from square and triangular waves to sample players and interactive sound generators.
The boxes were originally conceived by Camino Beck as part of an open-source experimental art project with the goal of stimulating STEAM in education, from high school to college, and to allow artists, engineers and computer scientists, or pretty much anyone interested, to explore programming and digital fabrication. They were developed and fabricated in “Inventoria”–Costa Rica’s own idea of a Makerspace.
More than just a finished project, these boxes are designed to be hacked and to help move away from more conventional ways of thinking when it comes to sound.
These boxes use coding as a way to “write music,” and to take advantage of the diversity of physical low cost sensors to trigger sound. Some of the boxes play with basic waves, just creating basic PWM, and others go from there to create arpeggiator and interactive. They will be used in several workshops and experimental music concerts in Costa Rica.
A few weeks ago, an announcement was posted on the Arduino Forum mentioning new improvements on the software side of the Arduino/Genuino 101. With this release, the board–which was developed in collaboration with Intel–is reaching its full potential, with not only better code generation but unlocking useful features to make your sketches even more interactive as well.
You can easily upgrade the core using the Arduino IDE’s Board Manager (pictured below), while Arduino Create users will be automatically updated, so no action is required–the cool thing about the cloud!
Did you know that if you take a head of romaine lettuce and eat all but the bottom, then place it in a bowl of water, it will regrow? This fun fact actually inspired Instructables user Evandromiami to develop a deep water culture hydroponic system that would optimize the process for him.
The lettuce is grown on top of a five-gallon plastic bucket filled with water under full spectrum lights, while an Arduino 101 monitors the light, humidity, temperature, water, and pH levels measured by a set of sensors. The system is controlled over Bluetooth, which enables the Maker to adjust settings and receive notifications on an LCD screen. All the electronics, including the Curie-based board, are tucked away inside a power strip and the entire hydroponic farm lives inside an A/C closet. (more…)
Arduino and Genuino Education is a worldwide-leading school initiative bringing technology into the hands of teachers and students to create a more inventive learning experience. It offers multiple platforms, including research-based projects like PELARS and in-class programs such as Creative Technologies in the Classroom (CTC), all of which are present at this year’s Maker Faire Bay Area.
With CTC, students are able to learn basic programming, electronics, and mechanics concepts in an approachable, playful way through a series of coding projects and easy-to-assemble experiments.
Arduino’s one-of-a-kind STEM program has been implemented in nearly 500 schools throughout the globe, resulting in an overwhelming satisfaction rate among both students and teachers alike. 95% of instructors continue to use the curriculum in their classrooms year after year, while more than 13,000 students have already participated.
CTC 101 — running on Arduino 101 — is divided into four distinct stages:
Teacher training (one week)
Themed modules (five modules, 10 weeks)
Student projects (nine weeks)
Technology fair (one day)
Each program comes with a CTC 101 Toolbox consisting of:
Sets of electronics components and pre-cut mechanical parts
Last night Massimo Banzi was Guest Judge on Intel America’s Greatest Maker – episode 4 and had the difficult task of evaluating the teams and their projects competing in the Make or Break rounds for $100,000 and a spot in the million dollar finale.
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 these 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. (more…)
