Media artist @vtol_’s synth puts the metal in metal ruler! The instrument can be classified as an automated plucked contrabass monochord. Changing the pitch is done by quickly changing how far the ruler is extended relative to the nut. Movements, plucks, and presses of the ruler along the nut are driven by powerful and fast motors, which allows playing pretty fast lines. Two pressing motors can work simultaneously or selectively, which allows you to choose the register: the range and amplitude of oscillations depends on the place in which the ruler is clamped before the pluck. The sound is picked up by a small piezo element, which is hit by a ruler directly (the instrument has no resonator). The Arduino-powered device is equipped with 12 touch keys, each of which can be reassigned to a specific length of the ruler. A small OLED display is used to select modes, tune notes, and indicate processes and states. 📏 create.arduino.cc/projecthub/vtol

When Geert Wanten’s wife got tired of opening up the chicken coop to let them out in the morning, he decided to automate the situation using an Arduino Nano. Wanten’s DIY system calculates the sunup/sundown via info from a DS1307 RTC module, pulling the door up with a gearmotor and a spool of fishing line. Once it’s time to drop the door and close things up, the motor is reversed, keeping the chickens safe at night. 📷 instructables.com/member/g.wanten

The new Arduino IoT Cloud Remote app that lets you control your Internet of Things projects on the go. ☁️📲 Download it from the App Store today! Coming soon to Android.

Prof. Vijay Janapa Reddi of @harvardseas, the TensorFlow Lite Micro team, and @edxonline are sharing a series of short TinyML courses this fall that you can observe for free, or sign up to take and receive a certificate. We're really excited to support this groundbreaking program! An off-the-shelf Arduino TinyML kit will be available to edX learners for purchase. It includes an @arm Cortex-M4 MCU with onboard sensors, a camera, and a breadboard with wires — everything needed to unlock the initial suite of TinyML application capabilities, such as image, sound, and gesture detection. 👉 blog.tensorflow.org

📢 Arduino and Google are excited to announce that the Science Journal app will be transferring from Google to Arduino this September! Arduino’s existing experience with the Science Journal and a long-standing commitment to open source and hands-on science has been crucial to the transfer ownership of the open source project over to Arduino. The Google versions of the app will officially cease support and updates on December 11th, 2020, with Arduino continuing all support and app development moving forward, including a brand new Arduino integration for iOS. Arduino Science Journal will include support for the Arduino Nano 33 BLE Sense board, as well as the Arduino Science Kit, with students able to document science experiments and record observations using their own Android or iOS device. The Science Journal actively encourages students to learn outside of the classroom, delivering accessible resources to support both teachers and students for remote or in person activities. For developers, the Arduino version will continue to be open: codes, APIs, and firmware to help them create innovative new projects. In 2019, we released the Arduino Science Kit, an Arduino-based physics lab that’s fully compatible with the Science Journal. Moving forward, all new updates to the app will take place through Arduino’s new version of the Science Journal, available in September. The new Arduino version of the app will still be free and open to let users measure the world around them using the capabilities built into their phone, tablet, and Chromebook. Furthermore, Arduino will be providing better integration between the Science Journal and existing Arduino products and education programs. 📱 Stay tuned for Arduino’s version of the Science Journal, coming to iOS and Android in September 2020!

PeterQuinn925 swims for exercise, and to train for the occasional triathlon, but when doing so he often zones out and forgets how many laps he has swam. To solve this problem without spending a lot of money on a commercial solution, he created his own counter using a Nano and an ultrasonic sensor. The sensor detects when a swimmer approaches, and the system calculates distance based on this, assuming that a lap is roughly 50 yards or meters. This info is announced audibly via a speaker/amplifier using an Arduino speech library and is shown on a 7-segment display. Still something of a prototype, the device is currently housed in a takeout food container, but it looks like an interesting and useful concept. 📷 github.com/PeterQuinn925

While many of us take playing tunes for granted, whether via MP3s, CDs, or streaming services, for others — such as many that are very young or old — actually figuring out the interface can be a challenge. To make it easier for the elderly (and children) to enjoy music, Ananords and his girlfriend created the Juuke box. The Juuke features an RC522 RFID reader to trigger specific songs stored on an SD card via a DFPlayer Mini, using a stereo jack and external powered speakers. The device is controlled by an Arduino Uno, and includes a volume potentiometer along with two light-up buttons — red to play/pause tracks, green for random playback. 📷 @ananordss

☁️📲 The perfect companion to the Arduino IoT Cloud! Develop your IoT solution online via a desktop, then monitor and control your dashboards on your mobile with the new Arduino IoT Cloud Remote app. Initially available for free for iPhone on the App Store (Android to follow in the next few weeks), the Arduino IoT Cloud Remote app gives you with the ability to access, monitor or control your IoT projects regardless of the time or place: • In the field: you can read the data from your soil sensors or start your irrigation system directly from anywhere. • In the factory: constant visibility of the state of your manufacturing process status, with the ability to control your automation remotely. • In the home: monitor your home automation systems, check your previous or actual energy consumption from the convenience of your sofa. The latest dashboard for the Arduino IoT Cloud comes with a host of enhanced features. Creating your dashboard via a desktop or tablet is quick and easy. The tool automatically configures your devices (including the secure crypto element) and automatically generates the main code for your project, making setup as straightforward as possible. A broad set of simple widgets to connect to the properties provides maximum versatility and enables you to set up a new dashboard in minutes. Your dashboards, how you like them — all dashboards are fully customizable, it’s possible to group devices and organize them in any sequence — just drag and drop to arrange the layout, and select from multiple options including graphs to visualize the data. You can gather and display data from multiple IoT devices in one dashboard, and control those devices as required through your dashboard to fully integrate your solution. The addition of the Arduino IoT Cloud Remote app to access, monitor, and control dashboards on the go via your phone is the final piece of the jigsaw. 👉🆓 iOS version is now available for free from the App Store.
