Introduction

This class allows you to control Arduino GPIO from Windows apps, with features including:

  • Reading and writing to digital pins
  • Reading analog inputs
  • Controlling servo motors
  • Sending data to devices and receiving data form devices through the I2C Bus Terminal

Step 1: Set Up Your PC

1.Download Visual Studio 2017 Here image2

2.Enable developer mode on your operating system

3.Download LattePanda.Firmata

LattePanda.Firmata is an open-source Firmata library provided by LattePanda, which is suitable for Windows apps developed in Visual Studio. This class allows you to control Arduino GPIO from Windows apps, with features including:

  • Reading and writing to digital pins
  • Reading analog inputs
  • Controlling servo motors
  • Sending data to devices and receiving data form devices through the I2C Bus

Step 2: Set Up the Arduino

1.Open Arduino. Then, select “StandardFirmata”

Create a project or use the sample project here.

1.Open Visual Studio 2017 and create a new application: createProject1 createProject2 2.Download the LattePanda.Firmata class library

3.Add the downloaded class library to your project. Next, open your Solution Explorer and right-click in the blank area, then add existing item. addClass1 4.Add the following code to Program.cs.

  • Add the following two lines of code before the line of code "namespace blinkYourBoard."

    using System.Threading;

    using LattePanda.Firmata;

    The first line of code controls delay commands and the second line is a LattePanda.Firmata class library namespace

  • Now add the following code into the body of the Main Function

Arduino arduino = new Arduino();
arduino.pinMode(13, Arduino.OUTPUT);//Set the digital pin 13 as output
while (true)
{
// ==== set the led on or off
arduino.digitalWrite(13, Arduino.HIGH);//set the LED　on
Thread.Sleep(1000);//delay a seconds
arduino.digitalWrite(13, Arduino.LOW);//set the LED　off
Thread.Sleep(1000);//delay a seconds
}

The complete code is as follows:

addCode

5.Finally check your project and debug if needed Connect your Arduino and click Start start Soon, you will find the LED of your Arduino blinking
