Grove Starter Kit for IoT based on Raspberry Pi

Building an IoT project on your Raspberry Pi has never been an easy task for many developers. This is due to the messy hardware connections involved, and complicated software programming. Seeed and Microsoft have worked together to alleviate some of these challenges by introducing the Microsoft IoT Grove Kit.

The GrovePi+ cape included in the kit is fully compatible with your Raspberry Pi 3 and Raspberry Pi 2 that both run Windows 10 IoT Core. With the easy-to-use Grove system, you are now able to connect up to 15 Grove modules to your Raspberry Pi simply through the Grove interfaces on the GrovePi+.

In addition to the high performance sensors and actuators, the kit contains a 5 inch HDMI Display and a RGB LCD with a backlight. The Microsoft IoT Grove Kit is a powerful platform on which to begin your exploration on the Internet of Things.

Please note this kit DOES NOT include the Raspberry Pi board. Please visit here to purchase separately.

!!!Note GrovePi+ and some of the code was designed by Dexter Industry. Click to get more information about Dexter.

Features

• Easy-to-use GrovePi+ that is compatible with Raspberry Pi B/B+/A+/2/3

• Plug-n-play Grove Modules for rapid prototyping

Part List

Hardware connection for GrovePi+

1.1 Connecting the GrovePi+ to the Raspberry Pi

First, mount your GrovePi+ on the Raspberry Pi. The GrovePi+ slides over top of the Raspberry Pi as shown in the picture below.

Ensure that the pins are properly aligned when stacking the GrovePi+.

Powering up the Raspberry Pi

To power the GrovePi+ and the Raspberry Pi, you can use the micro USB power port on the Raspberry Pi. Remember to use a good power adapter capable of supplying 2A at 5V. If you want to run the GrovePi+ in a standalone configuration, then you might find a USB power bank.

Install GrovePi C# library for Raspberry Pi

The GrovePi can be programed in C#, but first you should install the Windows 10 IoT C# driver library for GrovePi, There’re two ways to do this: install the NuGet package and use the GrovePi C# library code powered by Dexter .

Install the NuGet package

The GrovePi NuGet package for the current release is available. To install GrovePi for Windows IoT follow the following steps.

STEP1.

From the Tools menu, select Library Package Manager and then click Package Manager Console.

The Package Manager Console window is displayed.

STEP2.

Run the following command in the Package Manager Console.

PM> Install-Package GrovePi

More details at https://www.nuget.org/packages/GrovePi/.

Use the GrovePi C# library code

If you’re a senior programmer or you can’t install the GrovePi NuGet package successfully, you can download the library code by click this https://github.com/DexterInd/GrovePi/tree/master/Software/CSharp.

STEP1.

Move the two C# library projects “GrovePi” and “Driver” to the folder where your project resides. And add them to your project in Solution Explorer. For example, right click the Solution “GrovePiExamples ”, Add | Existing Project, as below shows.

Then add “GrovePi” and “Driver” to the Solution Explorer.

STEP2.

Set the C# library as the reference projects. Right click References and click Add References

Click Projects | Solution, and check box as shown in the red box below. Then click OK.

Now, you have already install the GrovePi C# library successfully.

All supported sensors are available through the DeviceFactory class.

Examples

Below are some simple examples of how to use the library.

• Measure Distance

Ultrasonic sensor plugged into digital pin 2 (D2)

var distance = DeviceFactory.Build.UltraSonicSensor(Pin.DigitalPin2).MeasureInCentimeters();

• Display Hello World

  Copy

   DeviceFactory.Build.RgbLcdDisplay().SetText("Hello World").SetBacklightRgb(0, 255, 255);

• Sound the buzzer

Sound the buzzer plugged into digital pin 2 (D2).

DeviceFactory.Build.Buzzer(Pin.DigitalPin2).ChangeState(SensorStatus.On);

Running Win10 IoT Examples on Rpi3

Here we have a list of example projects that show just how easy it is to start a project with the Raspberry Pi. These Raspberry Pi projects combine easy-to-use Grove sensors with the powerful Raspberry Pi. You can click here to download the GrovePi Example code for win10. You will need to press the green button “Clone or download” on the right and choose “Download ZIP”. Then you need to extract the ZIP in a location of your choice. Open the GrovePiExamples(win10).sln with your Visual Studio 2015, you can see there’re 12 projects in the Solution Explorer as the picture below shows.

Before you get started, please build GrovePi project first. This is because the other projects depend on it.

Hello World from RGB LCD

This example is meant to be your first project with the GrovePi+. All the parts used in this project are available in the GrovePi+ Starter Kit. Once mastered, you can move on to more complicated projects like connecting a display or other sensors to the Raspberry Pi.

• Step1: Set the HelloWorld(LCD) project as StartUp Project.

• Step2: Hardware connection.

Connect the RGB LCD to Port I2C-1 and power on the Raspberry Pi using the Grove wire connector.

• Step3: Deploy your app.

1) With the application open in Visual Studio, set the architecture in the toolbar dropdown. Select ARM.

2) Next, in the Visual Studio toolbar, click on the Local Machine dropdown and select Remote Machine.

3) At this point, Visual Studio will present the Remote Connections dialog. If you previously used PowerShell to set a unique name for your device, you can enter it here (in this example, we’re using my-device). Otherwise, use the IP address of your Windows IoT Core device. After entering the device name/IP select None for Windows Authentication, then click Select.

4) You can verify or modify these values by navigating to the project properties (select Properties in the Solution Explorer) and choosing the Debug tab on the left.

When everything is set up, you should be able to press F5 from Visual Studio.
