this is connector chip used for asynchronous serial interface and its task is to make voltage level operative for next connected device.it is usually used in pc and microcontroller interface
That depends on the specific microcontroller.
The PIC is a specific architecture of microcontroller.
to determine the state condition of microcontroller's input when microcontroller is reading the input port
The difference is base on the requirement of their0 application.
how push button interface with microcontrollor
PIC Microcontroller which means Peripheral Interface Controller. PIC Microcontroller is originally developed by General Instrument's Microelectronics Division.
The basic difference between the microprocessor and microcontroller is that we can interface a microcontroller directly means "for example we can directly connect a keyboard to microcontroller to any of its ports"....where as for microprocessor we can't interface directly...we require a circuit board since it requires ram,ic's.....etc.,! beyrojac mahinay
The difference between a single board computer and microcontroller is that a single board lacks a general purpose interface and the mass storage devices.

Its a 8051 based CPU with inbuilt flash memory(ISP - In-System Programming). It can be flashed through SPI(serial peripheral Interface). AT89C51RD2 has similar features but its flash memory can be programmed through serial interface (RS-232).
That depends on the specific microcontroller.
Yes. You probably don't want to do so directly unless it's a really small motor. An H-bridge, or similar circuit is probably easiest to use. The microcrontroller would interface with the computer, likely through a serial link. The microcontroller would then control the H bridge through several outputs. Depending on the microcontroller, H-bridge design, and motor to be controlled, the microcontroller might not be able to drive the H-bridge and an intermediate driver chip may be needed.
The 8051 can directly interface with a number of I/O. The 8255 just gives you the abilty to access 3 eight bit ports using a minimum number of control bits from the 8051

A Wii Remote is about $20, and a Nunchuk is about $25, so together they would be $45.
