A microcontroller can be described as a computer on a single IC including a processor core, memory, and programmable input/output peripherals. Program memory as NOR flash or OTP ROM is likewise frequently included on chip, and a normally small amount of RAM. Microcontrollers are intended for embedded systems, rather than the microprocessors which are utilized for PCs or other universally useful applications. Microcontrollers are utilized as a part of auto controlled items and gadgets, for example
Microcontrollers Microcontroller can be considered as a small size of computer on a chip. Because it consists of processor, random access memory (RAM), read-only memory (ROM) and input/output peripherals. Microcontroller is also named as embedded controllers, since it is part of an embedded system. According to Blacharski (2003) microcontroller defines as “an integrated chip that is often part of an embedded system”. The purpose of develop microcontroller is to evolve the performance and efficiency
about the 8051 microcontroller and board but also how to deal with it. Microcontroller vs. Microprocessor The first thing that needs to be done is to know the basics of what the 8051. The 8051 refers to a microcontroller. Microcontrollers are pieces of hardware that have set amounts on its parts, like RAM, ROM, and its input and output ports. Microcontrollers are more cost efficient than microprocessors, which need separate RAM, ROM, according to the needs of the user. Microcontrollers come in handy
Arduino Microcontroller It is said that each one of us has at least twenty microcontrollers in our houses or workplaces. According to a survey, there are more than two billion microcontrollers being manufactured annually. Everybody around the world could not even consider a day without these electronic components (John, 2013). Today, the world is evolving towards a computer-based and technology-dependent environment. Computers, robots and machines could be seen everywhere. Buildings and homes are

From my school days I had the curiosity of knowing
introduction of single chip microcontrollers, the hardware part was drastically reduced; so also the cost and size of the hardware has come down to a large extent. As a result almost all of the control circuits are designed over single chip microcontrollers. 2. SCOPE OF THE PROJECT The primary objective of this project is to make a simple circuitry for Air conditioner controller. This circuitry is based on the state of the art technology of Microcontrollers .The features of the project
The Intel MCS-51, commonly known as the “8051”, is a single chip microcontroller which was developed by Intel in 1980 for use in embedded systems. This “system on chip” accommodates 128 bytes of RAM, 4Kbytes of ROM, 2 Timers, 1 Serial port, and four ports on a single chip.[1] The rise in popularity and success of the 8051 brought forth different versions of the microcontroller from other manufacturers (Intel permitted so). Its popularity remains to this day for it provides a marketable availability
PIC microcontroller Brief History The first microprocessor was developed by a small company called Intel (Integrated Electronics) in the early 1970s. But it faced no consumer market so they decided to market the chipset as “general purpose” microprocessing system where digital logic chips would have been used. This idea was a success and the Intel team developed 4 bit microprocessor called the 4004. In 1974, the second generation microprocessor (the 8080) was fabricated as a single chip operated

“The important thing is not to stop questioning. Curiosity has its own reason for existing”. This quote by Albert Einstein best describes my life. The inquisitive nature that I posses has helped me to improve my knowledge. A person, who is curious enough to dig deep, is always the one who achieves success. I would describe myself as a person who asks these intelligible questions in order to surpass an older me. During my teenage in high school, I was praised as a person who is highly skilled in

ABSTRACT In this paper we discuss porting the Embedded Xinu operating system (OS) to the 8-bit Arduino Mega 1280 due to its ability to meet several constraints. A 64-bit Linux environment and associated tools are used to develop Xinu for the AVR. The steps to port Xinu can be split into several different steps. The final Xinu image for the Arduino is 35 KB in size without any compiler optimizations. We discovered interesting features of the platform such as the division of SRAM and are in a
It was only after careful consideration of my aptitude, interests and experiences gained while pursuing my under graduation in the field of Electronics and Communications Engineering that I have decided to pursue my masters in the field of Computer Science. The question here might raise why I am opting for Computer Science when I’m from Electronics background. While in my under-graduation, I always had a doubt how the systems are interrelated using networks and all the things related to Computers
Many different approaches are used to reduce power consumption at the circuit level design. Some of the main techniques are Transistor Sizing, Voltage Scaling, Voltage Islands, Multiple Threshold Voltages and Power Gating. There is a negative effect with each power optimisation technique used at the expense of performance or area. Rabaey (1996) states that Transistor Sizing (TS) technique is used to adjust the size of each transistor (smallest element in the digital system) or gate (group of transistors)
decodes the tone into a 4 bit number and main controller will unlock the door as shown in Figure 15. If button 2 is pressed on the keypad, hook off circuit will be activated to disconnect the call as shown in Figure 16. Then the microcontrollers need to be reset by changing logic at their RST pins, to make them ready for next turn. If button 2 is pressed on the keypad, hook off circuit will be activated to disconnect the call as shown in Figure 16. Some of the important
