How to Connect Standard USB Devices to your Android Device

Many of the Android devices on the market
today support USB OTG (On-The-Go). This allows
users to connect standard USB devices such as
keyboards, mice, or even extend storage using a
regular USB flash drive.
However, you can’t plug the peripheral device
directly into it as Android device does not have a
standard USB port. In order for your Android
phone or tablet to connect to the device, you’ll
need a USB OTG cable.
A USB OTG cable is a small cable with a male
micro-USB connector on one end and a female
full size USB port on the other, so that you can
plug it into the Micro-USB port on your device
and allows you to connect standard USB 2.0
devices. These kinds of cables can be purchased
for a dollar or two at Amazon .

Note : Not all Android devices support USB OTG
and no single USB OTG cable out there which is
compatible with every phone so be sure to read
the product description before purchasing one.
Once you have a USB OTG cable, just plug it into
your device and connect the USB device directly
to it, and your peripherals should work without
any additional configuration.
I have paired the USB OTG cable with my
Samsung Galaxy S3 and have found that the
adapter works with most standard USB devices.
USB Flash Drive
When you plug a flash drive into the USB
adapter, the device immediately displays the
contents. You are then free to view or
playback any media you have on the drive.
You can also move data from the USB drive to
your phone SD card by simply tapping and
holding the file you want to move.
USB Mouse
When you plug a mouse into your phone or
tablet, a pointer will show up on the phone
screen. You can then use your mouse to
swipe through pages, select apps and more.
USB Keyboard
If you find yourself doing a lot of typing on the
go, you can connect a USB keyboard to your
device. Once you plug it in using the OTG
cable, simply open up a notepad app and you
can start typing on the keyboard as usual. It’s
also possible to use shortcuts such as Ctrl+C
and Ctrl+Z.
USB Gamepad Controller
Its also possible to connect a gaming
controller to your Android device and play a
video game just like on the console. Just plug
the controller into the USB adapter and launch
a game such as GTA. Not every game works
with this, so you’ll have to do some testing to
find out if your favorite games will work.
These are just a few USB devices that have been
found to work with OTG cable on Android device.
My advice is to try other devices too, and see
how the OTG cable can add a lot of new
functions to your Android phone or tablet.

AirDroid is the best tool that lets you connect
your Android device to your PC over a WiFi
network. While you can always use the USB
connection method, but AirDroid helps you get rid
of these cables and make everything work
wirelessly. Recently, Airdroid team has released
a new version of the tool, AirDroid 3, which
offers a lot of new features and improvements.
One of the key features included in the AirDroid
3 is AirMirror, which lets you control your
Android device right from your PC. After your
Android device and PC connected to the same
Wifi network, the AirMirror feature will show you
the live screen of your Android device.
You can then do tasks like replying to messages,
sending messages via WhatsApp, and doing
literally everything that you can do on your
device. What makes this interesting is that you
can now write your messages using the physical
keyboard on your computer, so this will definitely
help you speed up your typing.
It is worth noting that the AirMirror feature is
only supported by rooted devices running
Android 4.0 Jelly Bean and higher (or if the
Android device is AirDroid-certified). Android 5.0
Lollipop doesn’t support this feature though.
In addition to that, AirDroid 3 for PC and Mac
now comes with a new notification feature called
Notification Mirror that allows you to view
notifications from any app you like and you can
also silent them if they tend to disturb you. As
many users around the globe constantly use
instant messaging services, this feature turns out
to be convenient as notifications are directly
pushed to the desktop in real time.
Setting up AirDroid is simple. All you need is
Airdroid app for Android and Airdroid app for PC,
both of which are free to download. After
syncing your account on both devices over a
WiFi connection, you are ready to go.

पृथ्वी पर सबसे अधिक मात्रा में पाया जाने वाला तत्व ‘ब्रिजमेनाइट’ की खोज

अमेरिकीभूवैज्ञानिकोंद्वारापृथ्वीपर
सबसे अधिक मात्रा में पाए जाने वाले तत्व
‘ब्रिजमेनाइट’ की खोज की.
कई तत्वों के निष्कर्षण के बाद
अमेरिकीवैज्ञानिकोंकीटीम
ने इस तत्व का नाम ब्रिजमेनाइट रखा.
इस तत्व का नाम 1946 में भौतिक विज्ञान के
क्षेत्र में नोबेल पुरस्कार जीतने वाले
भौतिक
विज्ञानी पर्सी ब्रिजमैन के
नाम पर रखा गया है. पर्सी ब्रिजमैन ने
उच्च दबाब क्षेत्र वाले विभिन्न भू-संरचनाओं
की प्रक्रिया को समझने में मदद
की थी.
अंतरराष्ट्रीय मॉयनोलॉजिकल एसोसिएशन
के अनुसार किसी भी नए
खोजे गए तत्व का औपचारिक नाम
नही रखा जाता. अब तक इस खनिज
को कैल्सियम टिटैनियम ऑक्साइड वाले पेरोव्स्काइट
से जाना जाता रहा है, क्योंकि इंटरनेशनल
मॉयनोलॉजिकल एसोसिएशन के अनुसार
किसी खनिज को तब तक पृथक नाम
नहीं किया जा सकता जब तक
कि उसकी जांच के लिए उसका पर्याप्त
नमूना नहीं मिल जाता.
अमेरिकी भूवैज्ञानिकों के एक दल ने
उल्कापिंड से अध्ययन के लिए पर्याप्त मात्रा में इस
तत्व का नमूना करने के बाद आधिकारिक तौर पर
इसका नाम ब्रिजमेनाइट दिया.
ब्रिजमेनाइट-
• ब्रिजमेनाइट
पृथ्वीकीभीतरीपरत
की 70 प्रतिशत मात्रा में तथा 38
प्रतिशत पृथ्वी की कुल
अवयवों से बना है.
• यह उच्च घनत्व वाले मैग्नीशियम
आयरन सिलिकेट से बना है.
• पृथ्वी के केंद्र की ओर
670 किलोमीटर गहराई से
भीतरी परत शुरू
होती है और इतनी अधिक
गहराई के कारण ही वहां मौजूद इस
तत्व का नमूना मिलना बेहद कठिन था.
