Microcontrollers as the name suggests, are small controllers. They are like single chip computers that often embedded into other systems to function as processing / controlling unit, microcontrollers are single chip...
Microprocessor – controlled temperature system is used to Read the temperature in a room Display the temperature at LCD/LED panel Turn-on a fan if the temperature is above the limit. Turn-on a heater if the temperature is...
Memory Interfacing While executing a program, the microprocessor needs to access memory frequently to read instruction code and data stored in memory; the interfacing circuit enables that access. Memory has some signal...
The IOP is similar to a CPU except that it is designed to handle the details of I/O processing, Unlike the DMA controller that must be set up entirely by the CPU, the IOP can fetch and execute its own instructions. IOP...
Data manipulation instructions enable the PLCs to take on additional characteristics that are beyond the conventional relay equivalent instruction. It allows the movement, manipulation or storage of data in either single or...
Microprocessor Based Controllers Microprocessors are essential to many of the products we use every day such as TVs, cars, radios, home appliances and of course, computers. Microprocessor based controllers are also called as...
COMPONENTS OF AUTOMATIC CONTROL SYSTEM The basic components of an automatic control system are error detector, Amplifier and Controller, Actuator (power actuator), plant and sensor or Feedback system. The block diagram of an...
Introduction to Instruction Set Architecture of 8051 Generally microprocessor alone is not a self-sufficient system. Instruction Set Architecture of 8051 It requires other components like memory and input/output devices to form a...
Overview of Optical Fiber Communications Optical Fiber Communications Ever since ancient times, people had a principal need to communicate with one another. This need created interests in devising communication systems for...
