What’s the difference between Arduino and Raspberry Pi?

If you’re at all interested in the world of computers and the Internet of Things (IoT), then you’ve more than likely heard of Raspberry Pi. The small but powerful microcomputer has been a smash hit in the DIY computing world since its introduction in 2012 and, now in its fourth generation, continues to go from strength to strength.

Before all that, however, came Arduino, a much more modest but still highly effective piece of hardware that’s stayed relevant in the rudimentary programming and prototyping market since arriving in the early 2000s.

No green thumb required: Open-source robots can now grow a small farm for you

If you’ve always wanted to grow your own fruits and veggies but could never quite make the time for it — technology is here to rescue you. At first glance, technology and farming don’t go hand in hand, but that’s old school thinking. In this day and age, technology and farming are a perfect match. With cheap sensors, simple phone apps, and available equipment, you can build your very own farming robot.

Give it power, water, and WiFi, and it will take care of the rest. FarmBot can plant, water, weed, and monitor the soil and plants with an array of sensors. All you need to do is harvest the produce once it’s done.

Arduino’s Violante Highlights Value of Open Source

Arduino is an open-source electronics platform based on a simplified hardware and software management system. Arduino provides many boards for every design target, and one of its latest boards is Portenta for the industrial market. At its heart is STMicroelectronics’ microcontroller, with a dual-core Cortex-M7 and Cortex-M4 on the chip.

In this video interview with EE Times Europe, Fabio Violante, CEO of Arduino, discusses the value and role of open source as well as the increased interactions between children and technology. “There’s a lot of talking about open source, but not all the people understand very well what open source means, in many cases, it is sort of a synonymous with free so people just misinterpret the this concept,” Violante said.

Open-source, Arduino-based wearable biometric sensor EmotiBit meets Kickstarter goal

A new biometric, wearable sensor module based on Arduino is now available on Kickstarter. Dubbed EmotiBit, the open-source device can detect emotional, physiological, and movement data via more than 16 biometric signals.

“Wear in any orientation, anywhere on the body, and start measuring biometric signals! Built-in slots make it easy to wear EmotiBit any way you want,” reads the Kickstarter page. Since the data is 100 percent user-owned, it can be recorded directly to the built-in SD card, and viewed through a cross-platform visualizer available for Mac, PC, and Linux, and built on the OpenFrameworks creative-coding toolkit.

EmotiBit open source wearable biometric sensor

A new open source Arduino driven wearable biometric sensor has been created by the develop and team at EmotiBit, offering an easy-to-use sensor capturing high-quality emotional, physiological and movement data that is 100% user owned. Thanks to its open source design and Arduino compatibility data from the sensor can be streamed wirelessly to any platform, enabling artists and makers to unlock new perspectives on biometric signals.

The data is 100% user-owned and can be directly recorded to the built-in SD card, empowering anyone to explore their own health and wellness without reservations about where that data might end up.EmotiBit is able to detect 16+ biometric signals that are constantly traveling throughout our bodies, reflecting our moment by moment physiological and emotional changes.

Eyecam open-source webcam will make you feel spied on

Most people will use webcams connected to a computer or integrated into a laptop without thinking about the possibility of being spied on, but Eyecam will certainly raise awareness and make you feel like somebody is truly watching. The open-source webcam is shaped like a human eye and acts like one thanks to a Raspberry Pi camera and an Arduino board controlling six servos for eyeball, eyelids, and eyebrows movements.

The project was conducted at Saarland University in Germany, and Eyecam looks amazingly realistic – and creepy – with the eyeball and eyelids moving, especially when face tracking is enabled, and expressions are possible with servos controlling the eyebrows.

Open Source Electric Vehicle Charging

Electric vehicles are becoming more and more common on the road, but when they’re parked in the driveway or garage there are still some kinks to work out when getting them charged up.

Sure, there are plenty of charging stations on the market, but they all have different features, capabilities, and even ports, so to really make sure that full control is maintained over charging a car’s batteries it might be necessary to reach into the parts bin and pull out a trusty Arduino.

Open Source Hardware will revolutionize the way we learn Electronics

At CircuitsToday, our vision is to freely distribute electronics knowledge. Now that means, we want any one with an interest in electronics to learn as much as he would like. We make this easy by giving away free content in the form of practical circuits and theoretical explanation. In a way we can be called as an “open source” but not exactly! We have not associated this website with any open source movement so far.

For all these years we were focused on developing analog circuits and theory of basic electronics concepts and we are not done yet! We will still continue our expedition in the analog world but at the same time we are looking forward. We see things are changing!

Arduinos, 3D printing, and more at Red Hat open hardware day

The Opensource.com team gathered in one of the large conference rooms at Red Hat tower in Raleigh on March 21 to make an open hardware day of it.

We ordered some delicious burritos and discussed how the next few hours would unfold. We decided we’d load up Arduino software on my laptop, switch on the ginormous monitor in the front of the room, and see if we could make some blinky lights happen—maybe even make an LED display come to life with something like: “Opensource.com for the win.” After we ate as much queso dip as possible, we opened up our newly purchased Starter Kit for Redboard and got to work.
