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.

Calculation part:

There is little bit calculation. LM35 gives analog output. It's linearity is 10 mV/°C
which literally means for rise in temperature of 1°C, there be an increment of mV from output of lm35. It's graph is linear. It's temperature range is from: -55°C to +150°C.
Since, we are using LM35 it is calibrated in terms of degree celsius. There are other variants available like lm235 and lm335.

Arduino Code: 

The code is very simple

/*
Code Starts
*/


float val=0.0;

void setup() {
Serial.begin(9600);
}

void loop() 
{
val=analogRead(A0);
val=(0.4887*val);
Serial.println("VALUE OF TEMPERATURE IS: " + String(val) );
delay(1500);
}

/*
Code Ends
*/

Make computer apllication 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.

Massive Microsoft Machinations For Makers

If you’re not stuck in the tech news filter bubble, you may not have heard the Microsoft Build Developers Conference is going on right now. Among the topics covered in the keynotes are a new Office API and a goal to have Windows 10 running on a Billion devices in a few years.

There are, however, some interesting things coming out of the Build conference. Windows 10 is designed for hackers, with everything from virtual Arduino shields running on phones, Windows 10 running on Raspberry Pis, and Visual Code Studio running on OS X and Linux.

This is not the first time in recent memory Microsoft has courted the maker market. Microsoft begrudgingly supported the hardware dev scene with the PC version of the Microsoft Kinect, and a year or two ago, Microsoft rolled out drivers for 3D printers that were much more capable than the usual serial interface (read: the ability for printer manufacturers to add DRM). To the true, tie-die wearing, rollerblade-skating, acoustic coupler-sporting, Superman III-watching hackers out there, these efforts appear laughable – the product of managers completely out of touch with their audience.

Depending on your perspective, the new releases for the Arduino, Raspberry Pi, and other ‘maker-themed’ hardware could go one way or the other.

As far as educational efforts go, the Windows Remote Arduino and Windows Virtual Shields for Arduino are especially interesting. Instead of filling a computer lab up with dozens of Arduinos and the related shields, the WVSA uses the sensors on a Windows 10 smartphone with an Arduino. Windows Remote Arduino allows makers to control an Arduino not through the standard USB port, but a Bluetooth module.

If Arduinos aren’t your thing, the Windows 10 IoT preview for the Raspberry Pi 2 and Minnowboard Max is out now. The Win10 IoT distribution does not yet have working WiFi or Bluetooth, making it the single most useless operating system for Internet of Things devices. It was, however, released at the Build conference.

Also announced was a partnership with a fabulous hardware project hosting site, Hackster.io. Microsoft and Hackster.io will be collaborating with hackathons and other events focused on Windows technology. I get why they wouldn’t want another, vastly more popular project hosting site doing this, but I’m a little confused at why Instructables wasn’t the top Microsoft pick.

As always, you may express your infinite derision in the comments below. Spelling Microsoft with a dollar sign will result in a ban.
