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.

Taking great pictures means making them more vibrant enhancing saturation and contrast. Ynformatic has published some tips to help you do that by creating a DIY device to control a polarizer using an Arduino Pro Mini, an iPhone, and a screen from an auto-darkening welder’s mask.

A phototransistor located facing the iPhone’s flashlight LED is connected to both an external interrupt pin and an analog pin. Short pulses on the LED cause interrupts in the Arduino code which are used to synchronize the polarizer. Long pulses on the LED cause the Arduino to enter calibration mode. The time interval between syncrhonization pulses is continuously measured and divided into three equal parts. On receiving a synchronization pulse the voltage is set to 0V for one part, to the 45 degree voltage for one part and finally to 5V for one part. Voltage for the polarizer is supplied from an Arduino PWM output pin. To get a reasonably stable output the PWM frequency was increased to 32 kHz and smoothed with a second order RC filter. The liquid crystal display will be damaged by a constant DC voltage so a CMOS switch is used to alternate the polarity. A 2 kHz square wave generated from a free running Arduino timer is used to drive the switching.

An iPhone app written in Swift is responsible for the user interface and image processing.

Explore the schematic in the picture below, while the full source code for the Arduino and iPhone can be downloaded from here.

App development is not fun for everyone, and sometimes you just want to control a device from your phone with minimal work. Blynk appears to be a fairly put-together library for not only hooking up any Arduino or esp8266 to a phone through WiFi, but also through the net if desired.

Install the app onto your iPhone or Android device. Install the libraries on your computer. Next, modify your Arduino source to either pass direct control of a pin to Blynk, or connect Blynk to a virtual pin inside your code for more advanced control. If you want to go the easy route, create an account, log into the app, and drag and drop the interface you’d like. If the idea of letting some corporation host your Arduino project sends shivers down your spine, there is also an option to host your own server. (Editorial snark: Yes, it requires a server. That’s the cost of “simplicity”.)

There have been a few times where we’ve wished we could add app control to our projects, but installing all the libraries and learning a new language just to see a button on a screen didn’t seem worth it. This is a great solution. Have any of you had experience using it?

Have you ever thought of turning your iPhone and iPad into a platform of more than 40 Arduino shields? Now it’s possible!

The team of 1Sheeld have officially released the new 1Sheeld for iOS and it’s available for pre-orders for $39 instead of it’s original price $55 (shipping on May 2016).

You can  control robots, actuators, display sensors’ data and much more.  Take a look at the demo video:

Playing addictive and repetitive video games is a pleasure for some people but not so engaging for others. Valentin Haun found the solution to reach high score without getting bored: he made an Arduino Uno playing Timberman for him.
