Temperature on GUI using visual studio and arduino

In this post, first we will interface LM35 with arduino uno and then  upload this data through serial communication. With the help of visual studio we can make computer gui application and though this gui application, we can do lot of stuffs like temperature logger, humidity monitoring. The

Stuff we require:

1. Arduino uno with usb cable
2. LM35
3. Jumper wires
4. Visual Studio (I had used VS 2012)

Make connections as follows:

LM35 interfacing with arduino

Simply provide, Vcc and GND to temperature sensor (LM35) and it's output should be connected to A0 of arduino. You can connect it to any channel from A0 to A5.

Make computer application to control led on Arduino Uno

In order to control led of  Arduino Uno we need computer application. For that, we need Microsft Visual Studio. I am using Visual Studio 2012. I already had written the source code for it.

Source code is below:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace Arduino
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button3_Click(object sender, EventArgs e)
        {
            arduino.Open();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            arduino.Write("9");
        }

        private void button2_Click(object sender, EventArgs e)
        {
            arduino.Write("3");
        }

        private void button4_Click(object sender, EventArgs e)
        {
            arduino.Close();
            this.Close();
        }

        private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
        {

        }
    }
}

Below is design:

After this, upload the arduino program on to your board.
