A microcontroller is an economical computer-on-a-chip built for dealing with specific tasks, such as displaying or receiving information through LEDs or remote controlled devices. The most commonly used set of microcontrollers belong to 8051 family. 8051 Microcontrollers continue to remain a preferred choice for a vast community of students and professionals. Microcontrollers are designed for embedded applications. Embedded microcontrollers are used in automatically controlled products and devices such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys etc. By reducing the size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to digitally control even more devices and processes. Mixed signal microcontrollers are common, integrating analog components needed to control non-digital electronic systems.

Mixed signal microcontrollers are common, integrating analog components needed to control non-digital electronic systems. Microcontroller processors are designed to fill a smaller, more focused variety of roles while making use of less expensive and less complex circuitry. The main advantage of a microcontroller is that it allows electronic automation in situations where a full-sized computer is not needed. When the most modern technical engineering is applied to a microcontroller it allows the device to be extremely compact, making microcontrollers popular within mobile devices such as cell phones and PDAs. Embedded microcontrollers shine in situations where limited computing functions are required within an easily definable set of parameters. Microcontrollers excel at the low grade computational functions required to run devices such as electronic parking meters, vending machines, simple sensors and even home security equipment. Microcontrollers surround most of the people in their homes and offices, being present in devices such as televisions, remote controlled stereos and even the digital computer components of a timer on a newer stove. Through 8051 tutorial, the world can witness to the most revolutionary set of microcontrollers. The C programming language is the most popular programming language for programming embedded systems. Many microprocessors and microcontrollers can be programmed in C, and a number of C cross-compilers exist for that purpose. Irrespective of the fact whether in academics, you have studied embedded programming or not, you can pick up this subject at any time. On the internet, various books, training materials, code sample and detailed tutorials are available. The available tutorials are worth going for as they cover an extensive knowledge on every area. Various other tutorials like 8051 microcontroller tutorial, are also available on internet which will give you a detailed background study of the microcontroller, how to write software to read from or write to the ports on 8051 microcontroller. There are many different microcontroller families, each with their own assembly language with its own unique quirks. These tutorials cover some basics of must have knowledge of assembly language common to most microcontrollers. These microcontroller tutorials help in easy understanding and visualization of the instruction set and are quick to understand.
