  Architecture of 8051 microcontroller  Oscillator and clock generator  All operations in a micro controller by the help of and oscillator clock. The oscillator click pulse generated to pulses by which all internal operations.a resonant network connected through the PIN XTA1 and XTA2 form up ab oscillator. For this purpose a quartz crystal and capacitor are employed. ALU It is 8 bit unit.it performs logical operations like AND,OR,XOR. It manipulates 8 bit and 16 bit data .it calculated address of jump locations in relative branch instructions. It performs compare,rotate,and complement operations.it consist of boolean processor which perform bit,set,test,clear,and complement 8051 microcontroller consist 3 of general purpose registers.  and two of them are called "math registers". A and B and 32 are "bank of registers". ACCUMULATOR A REGISTER  It consist of 8 bit register .it address is EOH and it is bit and byte accesable results of arithmetic and logical operati...

  Arduino The arduino uno is a micro controller board on the ATmega328. It has digital input and output  pins,6 analog input, 16MHZ ceramic resonator, a USB connections, apower jack, and ICSP header,and reset button.  It was used to hardware and software purpose If you can easily connect to a computer with a USB cable cable or power it with a AC toDC adapter or battery to get start Special features of arduino  It has 1.0 pinout: added SDA and SCL pins that are near to the ARFF pin two other new pins placed near to the RESET PIN, the IOREF that allow the shields to adapt to the voltage provided from the board. UNO ARDUINO board Uno means one of the Italian. It named to mark the upcoming release of arduino 1.0.the UNO and version 1.0 will be reference version of arduino. Moving forward.it is latest version of arduino board. SPECIFICATIONS  Micro controller                            ATmega328 OP...

  INTRODUCTION  this is developed by Intel company,IN 1990S. DEFINION OF MICROCONTROLLER: A microcontroller is a low cost and small micro computer,which is designed to perform the specific task of embedded system like displaying micro waves information.  A general micro controller consist of the processor memory ,serial ports, pherrials.                      8051 microcontroller  TYPES OF MICROCONTROLLER: microcontroller controller are divided into various  categories  based on memory, architecture, bit,instruction sef 1.BASED ON BIT CONFIGURATION OF MICROCONTROLLER  1. 8-bit microcontroller:  This type of microcontroller  is used to execute arithmetic and logical operation like add, sub,mul. 2.16-bit microcontroller:This type of microcontroller is used to perform  arthimetic and logical operations where higher accuracy performance is required.  3.32- bit microcontroller: This t...
