Windows Form Application Using Arduino Uno

Introduction

 

In my previous article, I explained about Bluetooth Connection using Arduino and in this article, I'll show you working with Arduino Uno using Windows Form Application.

 

Requirements

• Arduino Uno
• Led
• Arduino IDE
• Visual Studio IDE 

Connection

 

Anode Pin(+) to 3

Cathode Pin(-) to Gnd 

 

 

Programming

 

Arduino: You can refer my first article for explanation.

int led = 3;
void setup()
{
    Serial.begin(9600); //Baud Rate
    pinMode(led, OUTPUT);
}
void loop()
{
    char data = Serial.read();
    switch (data) //Selection Control Statement
    {
        case 'ON':
            digitalWrite(led, HIGH); // Sets the led ON
            break;
        case 'OFF':
            digitalWrite(led, LOW); //Sets the led OFF
            break;
    }
}

Windows Form:

 

Step 1: Once Visual Studio Community 2015 and select FILE, then New, Project… from the Menu.

 

 

Step 2: From the New Project window select Visual C# from Installed, Templates, then select Windows Form Application.

 

 

Step 3: Drag and drop the buttons in the designer window named ONLED and OFFLED.

 

 

Step 4: And drag and drop the SerialPort Tool in the designer window and it will hide one.

 

 

Step 5: Start coding.

using System;
using System.Windows.Forms;
using System.IO.Ports;


namespace ArduinoConnection
{
    public partial class Form1 : Form
    {
        private SerialPort newport;
        public Form1()
        {
            InitializeComponent();
            Code();
        }

        private void Code()
        {
            newport = new SerialPort();
            newport.BaudRate = 9600;
            newport.PortName = "COM4";
            newport.Open();

            button1.Enabled = true;
            button2.Enabled = false;


        }

        private void button1_Click(object sender, EventArgs e)  //Click Event For LEDON
        {
            newport.WriteLine("ON");  // LED ON

            button1.Enabled = false;
            button2.Enabled = true;

        }

        private void button2_Click(object sender, EventArgs e)  //Click Event For LEDOFF
        {
            newport.WriteLine("OFF");  // LED OFF

            button1.Enabled = true;
            button2.Enabled = false;

        }
    }
}

Explanation

1. using System.IO.Ports is a Namespace
2. Create the object named as newport 
3. newport = new SerialPort(); //Intialize the new instance of Serial Port Class
4. newport.BaudRate = 9600; //Set the Serial Baud Rate for transforming the data
5. newport.PortName = "COM4"; //Set the COM Port
6. newport.Open(); //Port Open
7. button1.Enabled = true; // Conditions that true means Ledon
8. button2.Enabled = false; // Ledoff
