Remote working with Arduino: An intro to the Arduino IoT Cloud

via Arduino Blog

As more of us have restrictions on leaving our houses, the time we take away from physical social interactions (namely “going out”) is put back into extracurricular activities. We catch up with old hobbies and bring new ones into our lives.

While baking is proving to be one of the most popular ones, testified by an unprecedented shortage of yeast and flour on supermarket shelves, there are activities for which gathering supplies hasn’t changed much.

We’d like to get you into learning something about the Internet of Things using our platform and boards.

If you’re reading this, you probably have some of the tools you need for the following tutorials, while the ones you don’t have are a click away.

We’ll start by learning how to connect a board to the Arduino IoT Cloud and in a matter of minutes have your environment data in an easy to read dashboard.

In the next installment, we’ll see how you can remotely control a device from a dashboard and maybe water your office plant while you’re stuck at home!

Getting started with the Arduino IoT  Cloud

A basic guide on how to set up the IoT cloud can be found here.

Using the MKR ENV Shield with the Arduino IoT Cloud

This tutorial walks through displaying values from an environmental shield on the IoT dashboard.

Can’t find a pulse oximeter? Create your own!

via Arduino Blog

As John Keefe notes in his project writeup, at-home pulse oximeters — which monitor the oxygen saturation in your blood — have been selling out due to the COVID-19 pandemic. While you could try hunt around and find one, he decided to instead make his own device using a SparkFun Pulse Oximeter and Heart Rate Sensor module and an Arduino Uno.

The sensor takes pulse and oxygen level readings from your fingertip, then shows the resulting numbers on an RGB NeoPixel shield. Although the unit is not medically approved to diagnose or treat medical conditions, it’s a neat display method, and it even features heart and lung icons to indicate what you’re seeing. 

Code for the build is available on GitHub.

This Arduino project lets you see your heartbeat

via Arduino Blog

It’s easy enough to check your heart rate, but Sharath Naik has designed a project that actually lets you see it instead. The roughly heart-shaped, 3D-printed device sits on a pedestal with four sections that are pushed out in response to your pulse.

The visualizer utilizes a servo and linkage system to physically actuate beating, and a MAX30100 pulse oximeter mounted to the base is implemented to track your heartbeat. This data is fed into an Arduino Nano board, which signals the SG90 servo to expand and contract the model in response to your own body. 

More info and code are available in Naik’s post, and you can see it in action below! 

arduino-cli 0.10.0 is out!

via Arduino Blog

The Arduino CLI is steady as she goes! The team is constantly fixing issues and modeling the user experience thanks to the community’s feedback.

Highlights for this release include:

  • board attach‘ command now also supports the upload port for an easier sketch upload
  • Minor UX improvements
  • Bugfixes

You can see the full list of changes here. We have also just opened a CLI dedicated forum section. Please check it out!

NEW! A remote teaching platform that supports learning at home with Arduino

via Arduino Blog

COVID-19 is playing a huge role in everything we do. With schools closed and a large number of countries under total lockdown, we want to support educators, parents, and students with hands-on electronic, programming, and coding lessons from home.

NEW: The Arduino Education remote learning platform

We have been working on several initiatives to support remote learning. Our aim is for children to still have access to hands-on STEAM lessons even while they can’t attend school. We are pleased to announce that to support homeschooling needs we have launched a remote learning platform.

What will you find on the remote learning platform?

This platform will deliver online support to educators, parents and students so they have the tools they need to feel comfortable and confident in completing successful STEAM lessons at home. On a weekly basis, we will post new helpful material including video tutorials, live sessions, and extra support with resources, ideas, and tips.

We will also be hosting weekly live sessions on Arduino EduVision. You can find all details, dates and times, and book the next coming session here

All the activities and tutorials in our remote learning platform currently support using the Arduino Starter Kit and Arduino Certification as learning tools in the home.

18 tips and tricks for educators new to remote learning

Many schools are set up for some kind of remote learning, but there are an equal number for whom this is a whole new world. It’s also true that while you probably have lesson plans ready for the upcoming semesters, it’s a whole different ball game to suddenly put all these lessons online without disrupting any learning. These 18 tips and tricks will help you if you’re new to remote learning.

We hope that Arduino Education programs can support you in enabling students to learn, innovate, and succeed at home by making complex technology simple to understand and use.

Keep safe!

All the best from the Arduino Education Team

Electromechanical 7-segment clock made with an Arduino and 28 servos

via Arduino Blog

Digital clocks are often made out of a series of 7-segment displays, which light up to represent the needed numbers. Michael Klements’ electromechanical project, however, doesn’t use LEDs, but instead physically flips 3D-printed segments into view with 28 micro servos. 

When in use, each segment’s bright green surface is clearly visible. When “off,” they’re turned to reveal a slim black edge that goes largely unnoticed.

The device is powered by an Arduino Uno, along with a DS1302 RTC module. Two PCA9685 16-channel PWM drivers control the motors directly, and as they run off of I2C, more servos/digits could even be added if needed. 

You can see it all in action below and read more about the timepiece in Klements’ blog post.
