When you connect a microcontroller to a sensor, display, or other module, do you ever think about how the two devices talk to each other?

What exactly are they saying? How are they able to understand each other? Communication between electronics is like communication between humans. Both sides need to speak the same language. In electronics, these languages are called communication protocols. First, we’ll begin with some basic concepts about electronic communication, then explain in detail how SPI works. SPI, I2C, and UART are quite a bit slower than protocols like USB, ethernet, Bluetooth, and WiFi, but they are a lot more simple and use less hardware and system resources. Serial vs. Electronic devices talk to each other by sending bits of data through wires physically connected between devices. [NE555]’s SMD Prototyping is a Work of Art. Over on twitter [NE555] has been posting beautiful SMD prototypes.

Back in the 90s when surface mount components gained widespread adoption, the quick and cheap PCB prototyping services of today were unavailable. This led many to develop their own approaches. Open Design Oscilloscope Could be (Almost) Free. If you could only own one piece of test equipment, it should probably be an oscilloscope.

Then again, modern scopes often have multiple functions, so maybe that’s not a fair assertion. A case in point is the Scopefun open hardware project. The device is a capable 2-channel scope, a logic analyzer and also a waveform and pattern generator. The control GUI can work with Windows, Linux, or the Mac (see the video, below). The hardware uses a Xilinx Spartan-6 FPGA. SPI. This library allows you to communicate with SPI devices, with the Arduino as the master device.

To use this library #include <SPI.h> A Brief Introduction to the Serial Peripheral Interface (SPI) Serial Peripheral Interface (SPI) is a synchronous serial data protocol used by microcontrollers for communicating with one or more peripheral devices quickly over short distances. It can also be used for communication between two microcontrollers. Digital Potentiometer MCP41100 and Arduino - 3.

The Art of Making a Nixie Tube. 5. Super E.D.F (American) - Midnight Intercept. Professor Emeritus Seymour Papert, pioneer of constructionist learning, dies at 88. Seymour Papert, whose ideas and inventions transformed how millions of children around the world create and learn, died Sunday at his home in East Blue Hill, Maine.

He was 88. Papert’s career traversed a trio of influential movements: child development, artificial intelligence, and educational technologies. Based on his insights into children’s thinking and learning, Papert recognized that computers could be used not just to deliver information and instruction, but also to empower children to experiment, explore, and express themselves. The central tenet of his Constructionist theory of learning is that people build knowledge most effectively when they are actively engaged in constructing things in the world.

As early as 1968, Papert introduced the idea that computer programming and debugging can provide children a way to think about their own thinking and learn about their own learning. Microsoft adds support for Arduino in a push to dominate IoT development. Microsoft has been, and continues to be, a major supporter of the Internet of Things (IoT) and all that entails.

The company believes that the ability of enterprises to interconnect just about everything and then collect the big data those connected devices create is going to be the next big thing in information technology. To be a part of it, Microsoft needs to make Windows 10 as friendly to IoT development as it possibly can. To that end, Microsoft announced that as of September 7, 2016, the Windows 10 IoT Core platform will support Arduino, a favorite programming language of IoT developers all over the world.

SEE: IoT developers: Master this coding language if you want to thrive Developer choices Developers programming for Windows 10 IoT Core have access to a multitude of programming languages, including C#, C++, Visual Basic, JavaScript, Python, and Node.js. Seeing the future.
