What is microcontroller??
These microcontrollers are made to work on many embedded products and this is possible because it can be programmed. Program written in Assembly or C language are loaded into the chip and has made to perform a specific task.So the programmer can write specific program to perform specific tasks and load it, to make the MCU work. Microcontrollers are designed for embedded applications or other general purpose applications. Embedded products are the products which uses a microprocessor (or microcontroller) to do one task and one task only. A printer is an example of embedded system since the processor inside it performs only one task i.e. getting the data and printing it.
Software for a variety of applications can be loaded and run.Of course the reason a PC can perform many tasks is that it has RAM memory and an Operating system that loads the application software into RAM and lets the CPU run it.In an embedded system there is only one application software that is typically burned into ROM.An x86 PC is connected to various embedded products such as keyboard, printer, modem, disk controller, sound card, CD-ROM driver, mouse and so on. Each one of this has a microcontroller inside it that performs only one task. For example, inside every mouse there is a microcontroller that performs the task of finding the mouse position and sending it to PC.
Microcontrollers find many of applications some of them are:-
Only few are mentioned here but today in this digital world there are numerous applications of Microcontrollers.
After all this now what can you all do????
Still many posts will be posted about Microcontrollers and Assembly language programming so keep watching.
Thanks for watching. Please share if you like the post.

Washington, Jan 8 (ANI): An Arizonan engineer has come up with a wearable LED television that can be worn as a jacket and shows episodes of American animated sitcom, The Simpsons.
David Forbes, an electrical engineer by profession, was keen on building something really cool to wear at the Burning Man festival. So he re-purposed a comparatively simple flexible circuit board covered with LEDs.
He made the first with 30 rows of four LEDs each and then contracted a manufacturer to build 175 more of them. He attached them to an old coat and was able to build a display with a 160 x 120 resolution, which he notes on his blog is exactly half that of an iPod, Discovery News reported.
The set-up comprises a chip similar to that used in scaling down the images for security cameras , and another chip similar to the one used in controlling big LED signs used for advertisements. Forbes was able to put together his wearable display by adding a small set of circuits that convert video output of the iPod to the smaller resolution.
A full wrap-around display is priced at 39,995 dollars while a front-only will cost 24,995 dollars. Wait time is around four months. (ANI)

Technology is rapidly growing in the world.There might be some day in which things happen like self healing of electronics from damages due to temperature issues. The day is not so far..!!
University of Illinois engineers were able to create a method in which electronics with damaged circuits would be able to automatically repair themselves.The another shocking thing in this is that they are going to heal themselves with in 100 microseconds (100x10^-6 sec).
So in the upcoming years all the electronic gadgets uses this type of technology so that the gadgets will have long life and more durable.
The self healing technology involves creating circuits with gold lining and a layer of micro capsules. The damage for the circuits is mainly due to temperature effect. i.e circuits will get heated up and the heat will damage or cracks the circuit.
When such things happen due to temperature the microcapsules will automatically disperse themselves into the cracks, filling the gap and restoring conductivity to the circuit.
