This New Nano Pack Has EVERYthing You Need

via Arduino Blog

The Arduino Nano Every is now available in a 3 and 6 pack – perfect for running a course or powering all your projects with Arduino.

For those countless creations requiring a small and easy to use microcontroller board, the Nano Every has the tiniest Arduino form factor out there measuring just 45x18mm. Whether you’re working on a low-cost robotics project for the entire classroom or presenting a complex prototype with many functional blocks, this pack offers exactly what you need – a batch of Nano Every boards at a great price! 

This robust little board costs as little as €7.50 each ($9.30 each) in the 6 pack, saving €0.50 ($0.60) per board versus the single. It’s now more affordable than ever to forecast the local across town by building your own little band of Gnome Weather Forecasters in your class.

TipText enables one-handed text entry using a fingertip keyboard

via Arduino Blog

Today when you get a text, you can respond with message via an on-screen keyboard. Looking into the future, however, how would you interact unobtrusively with a device that’s integrated into eyeglasses, contacts, or perhaps even something else?

TipText is one solution envisioned by researchers at Dartmouth College, which uses a MPR121 capacitive touch sensor wrapped around one’s index finger as a tiny 2×3 grid QWERTY keyboard.

The setup incorporates an Arduino to process inputs on the grid and propose a number of possible words on a wrist-mounted display that the user can select by swiping right with the thumb. A new word is automatically started when the next text entry tap is received, allowing for a typing speed of around 12-13 words per minute.

Cisco switches converted into a cocktail machine

via Arduino Blog

If you want to whip up a cocktail, you can measure out the components by hand, or you could use a robotic assistant like this setup by creator Sven Tantau.

Tantau’s project employs an Arduino Nano to control 24 peristaltic pumps via a relay card, plus an ESP32 to run a web interface and send I2C commands to the Arduino letting it know which pumps to enable.  

The pumps, along with the relays and other components, are arranged inside the stripped shell of two Cisco Catalyst switches. In fact, the only electrical part from the router that’s still in use is the 12V power supply. 

This does, however, do a fantastic job of looking good while hiding the electronics inside, and transport tubing is nicely arranged on a 3D-printed grid where the Ethernet plugs once connected!

Audio preamplifier with tiny OLED display and unique case

via Arduino Blog

As spotted here, Sam Izdat decided to make a preamplifier for a friend who provides voice talent for audiobooks and the like. The primary audio circuitry for the build is provided by a purchased PCB based on the INA217 chip from TI, but from there things get a bit more interesting.

To complete the project, Izdat added a tiny Arduino-powered OLED display. This shows a VU meter, along with a variety of other animations, seen through a window in the enclosure made from a broken wristwatch. 

The device was prototyped using an Arduino Uno, while a Nano was embedded in the final product, allowing everything to fit into the unique compartmentalized enclosure that he constructed.

The amplifier is based on the Texas Instruments INA217 chip, with an Arduino Nano and 128×64 OLED display providing the visualization. [Sam] was able to find a bare PCB for a typical INA217 implementation on eBay for a few bucks (see what we mean?), which helped get him started and allowed him to spend more time on the software side of things. His visualization code offers a number of interesting display modes, uses Fast Hartley Transforms, and very nearly maxes out the Arduino.

Tell time on a three-module voltmeter clock

via Arduino Blog

Father’s Day 2018 has come and gone, but it’s never too early to start planning for next year. As seen here, Michael Teeuw decided to build a clock out of three analog voltmeters for his dad in 2017. After getting sidetracked last year, he was finally able to complete it on time for 2018!

Teeuw’s clock features a trio of indicators, properly scaled and labeled for hours, minutes, and seconds, with control via an Arduino Nano, along with an RTC module for accurate timekeeping. Each indicator is housed in its own 3D-printed module, with white LEDs added for visibility. 

If you’d like to build your own, Teeuw’s code is available on GitHub and the 3D print files can be found on Thingiverse.

Arduino timekeeper displays red for stay in bed

via Arduino Blog

If you have young kids, you’ve probably realized that they don’t exactly like to sleep in. While their energy levels are enviable, if their clock-reading skills haven’t yet caught up, this device by maker “JonathonT” looks like a great and simple solution.

With help from an Arduino and an RTC module, Jonathon uses a trio of LEDs to show red for “stay in bed,” yellow for “almost time,” and green to indicate “you can get up.” While the current 7:00am starting time might still seem early to some, when compared to his son’s previous 5:30-or-so awakening, this is a huge improvement. Cleverly, the LEDs are diffused with a normal white plastic stadium cup with wax paper inside, making it a very accessible project!

GREEN MEANS GO!!! RED, STAY IN BED!!! This simple, inexpensive Arduino real-time clock can be set to light up LEDs at whatever time necessary. For us that means at 6:00am it turns RED, STAY IN BED. Then 10 minutes before 7:00am it turns YELLOW giving the indication it is almost time to come out and to play in your room. Then at 7:00am… “The light is GREEN!!!”, he says, as he bursts into our room each morning no earlier than 7:00am. What a lifesaver!!!
