The key board here we are interfacing is a matrix keyboard. This key board is designed with a particular rows and columns. These rows and columns are connected to the microcontroller through its ports of the micro controller 8051. We normally use 8*8 matrix key board. So only two ports of 8051 can be easily connected to the rows and columns of the key board.

When ever a key is pressed, a row and a column gets shorted through that pressed key and all the other keys are left open. When a key is pressed only a bit in the port goes high. Whi ....etc

ARM stands for Acorn RISC machine is a family of instruction set architectures for computer processors based on a reduced instruction set computing (RISC) architecture. And in simple word ARM is Processor Achitecture .

Many of newbiees and students have misunderstanding that ARM is microcontroller or processor, but actually ARM is Architecture which is used in many processors and microcontrollers.

Short History of ARM ?
The British computer manufacturer Acorn Computers first developed ARM in the 1980s to use in its personal computer. ....etc
