[Tutorial] How to set up Blockly with Windows 10 IOT Core and raspberryPI
In this blog post you’ll learn about IoT Core Blockly, a new UWP application that allows you to program a Raspberry Pi 2 or 3 and a Raspberry Pi Sense Hat using a “block” editor from your browser:
You create a program with interlocking blocks, which will run on the Raspberry Pi. For example, you can control the LED matrix on the Sense Hat and react to the inputs (buttons, sensors like temperature, humidity, etc.).
IoT Core Blockly was inspired by these other super interesting projects:
- BBC micro:bit and the block editor (check out io as well)
- Google Blockly open source block editor
- Raspberry Pi Sense Hat (and the handy C# NuGet library from EmmellSoft)
In this blog post, we will show you how to set up your Raspberry Pi with IoT Core Blockly and get coding with blocks.
Set up IoT Core Blockly on your Raspberry Pi
What you will need:
- A Raspberry Pi 2 or 3
- A Raspberry Pi Sense Hat
- A clean SD Card (at least 8 Gb) to install Windows IoT Core 10 Insider Preview
- A computer or laptop running Windows 10, to install the IoT Dashboard
First, unpack your Sense Hat and connect it on top of the Raspberry Pi (having four small spacers is handy, but not required):
Now you will need to install the latest Windows IoT Core 10 Insider Preview on your SD card. Follow the instructions at www.windowsondevices.com in the “Get Started” section:
At this point, you should have the IoT Dashboard up and running on your Windows 10 desktop (or laptop) and your Raspberry Pi connected to the network (either Ethernet or Wireless). You should be able to see your Raspberry Pi on the IoT Dashboard “My devices” section:
In IoT Dashboard, go to the section called “Try some samples.” You will see the IoT Core Blockly sample:
Click on it and follow the instructions to install the UWP application onto your Raspberry Pi. After a few seconds, IoT Dashboard will open your favorite browser and connect to the IoT Core Blockly application running on your Raspberry Pi:
Press the “Run” button and the IoT Core Blockly application will start the “Heartbeat” program, and you should see a blinking red heart on your Sense Hat!
Try some other samples (the green buttons on the top). Select a sample, inspect the “blocks” in the editor and press the “Start” button to start this new program.
Try modifying an example: maybe a different image, color or message. IoT Core Blockly remembers the last program you run on the Raspberry Pi and will reload it when you start the Raspberry Pi again.
Under the hood
How does IoT Core Blockly work? How did we build it?
The code is on GitHub: https://github.com/ms-iot/samples/tree/develop/IoTBlockly.
You can clone the https://github.com/ms-iot/samples repo and load the IoTBlockly solution using Visual Studio 2015 Update 3.
The structure of IoT Core Blockly is simple:
- The main app starts a web server which serves the Blockly editor page on port 8000.
- At this point, you can browse to your Raspberry Pi <ip-address>:8000 from a browser and access the Blockly editor.
- We created custom blocks for specific Sense Hat functionalities (e.g. the LED display, the joystick, the sensors, etc.) and added them to specific “categories” (e.g. Basic, Input, LED, Images, Pin, etc.)
If you inspect the IoTBlockly solution from GitHub, you can see 4 different projects:
- SimpleWebServer: A rudimentary web server based on Windows.Networking.Sockets.StreamSocketListener.
Let us know if you want more details about how this works. We can definitely geek out more about this! J
IoT Core Blockly is a functional sample, but we think we can do more. For example:
- add more support for colors,
- add support for sounds,
- add support for voice (speech and speech recognition),
- add more blocks for GPIO, ADC, PWM, SPI, I2C,
- add blocks for other “hats” (for example, the GrovePi),
- send/Receive data to/from the cloud, over BT, etc.,
- leverage the io environment,
- improve the stability of the web server.
First, though, we want to hear from you J How you use IoT Core? What would you change or improve?
Don’t forget, IoT Core Blockly code is here on GitHub, and we gladly accept help, contributions and ideas!
if you are interested please share comment, I would add more turorial on this for the specific peripherals.http://iotneed.com/2017/03/04/tutorial-how-to-set-up-blockly-with-windows-10-iot-core-and-raspberrypi/BOT & Cloud AppsElectronicsKnowledgebaseUncategorizedIn this blog post you’ll learn about IoT Core Blockly, a new UWP application that allows you to program a Raspberry Pi 2 or 3 and a Raspberry Pi Sense Hat using a “block” editor from your browser: You create a program with interlocking blocks, which will run on the...ArvinshArvindam Jainadmin@iotneed.comAdministratorNatrualist, Technologist, Experminatlist having keen interest in IOT and Bots.IOTNeed
