Arduino launches Create platform for Internet of Things (IOT) collaboration


In early April 2016, the Arduino organization announced a complete change in strategy for how Arduino users will code and compile projects. Arduino Create is a brand new platform that allows you to code and compile online, share projects, and tap into existing community resources with much less effort than has ever been possible before.

Tutorial: Using Atmel Studio 6 with Arduino projects

The Atmel Studio 6 start screen.

In our previous Atmel tutorial, we talked about how to set up the powerful AVR Studio 5 IDE to incorporate Arduino libraries and projects. As flexible as AVR Studio 5 is, it had a few issues, and Atmel has been hard at work hustling the next major version out the door. Now, rebranded as Atmel Studio 6 (no longer just for AVRs!), the new version promises to be better, faster, and easier to use. Here, we’ll show you the quickest way to get up and running if you want to use Arduino code with all of the new features.

Note: This article explains how to set up the Atmel Studio 6 IDE for use with Arduino projects, step-by-step.  It also notes on general setup for working with Atmel devices, background on the pros/cons of working with AVR Studio, and a few other tips.  A table of contents is below; feel free to skip to any section that interests you.

AVR math optimization

Following up on our previous post on understanding floating point math and speed of operations on 8-bit AVRs, we ran across an excellent article today on Arduino math optimization. Alan walks through his implementation of an exponential moving average algorithm. An exponential moving average normally requires floating point arithmetic, but due to the lack of native support on 8-bit AVRs, Alan worked out a way to do it with fixed point math.

After some experimentation, he was able to get his version running quite a bit faster than the floating point version, and offers a detailed writeup and tips along the way. Just as we found in our brief testing, the easiest AVR math optimization is to avoid division, since these processors don’t have a native divide instruction. If you’re looking to squeeze every last drop of performance out of your 8-bit chip and can’t (or won’t) upgrade to something more powerful, check this out for some good ideas.

The top 5 Arduino projects for advanced hackers

As the Arduino surges in popularity, people keep dreaming up crazier and more complex ways to use it. We’ve rounded up five of the most impressive Arduino projects on the web to show what’s possible with such a versatile and inexpensive platform. Be warned – these projects aren’t for beginners, but if you’re looking for a challenge and something to brag about, they could be just the ticket.

Arduino open source tracking device leverages Kickstarter

A new Kickstarter project aims to provide a low-cost, open source platform for building a GPS tracking device. The author, Wayne Truchsess of DSS Circuits, explains that a few years back, his brother in law had a PS3 stolen during a long power outage in the depths of winter. Not wanting to repeat history, Wayne bought a fake PS3 case on eBay and developed his own prototype position tracker to put inside it.

The tracker consists of a GSM cellular modem, a GPS unit, and an accelerometer, all tied to an Arduino and a LiPo battery to provide brains and power, respectively. Normally, the device lies in wait, asleep to save power. If it detects motion, it turns on the modem and alerts a preconfigured phone number via SMS. The owner can then respond with various commands to turn position tracking on or put the device back to sleep.
