understanding difference btween different uC...

[gouravkhanijoe]

i hav used uC 89s52 i.e. 8051 now i want to know about other microcontrollers....
what is the basic difference btw 8051 PIC AVR ARM7 ARDUINO and many others
why do we need them ?
also tell me about the specific applications of each of these microcontrollers i mentioned...
which one best suits robotics ????
so many ques in my mind
need help ....

8051 and AVR are ALMOST same..AVR is with faster speed, more peripherals like builtin adc, comparator and PWM channels. its easy to program and even has builtin oscilators upto 8mhz. AVR has in system programming capability. it is good for hobby robotics. for more professional robotics projects PIC is prefered. i dont know much about PIC.

ARDUINI is just an interface board and a MADE easy software for hobbyist. it is easy to interface..its controller is AVR.
this might help

thanxxx sir
so i got the idea to prefer avr after 8051 ....
it helped...

BDW PIC is preferred for robotics and widely used in industrial projects too...

ohk....but i hav a doubt PIC is preferred bcz of its inbuilt special features but if one wants to make a simple robot cant he build it with 8051 at the cost of some speed factor...??

yes offcourse you can build a simple robot with 8051, like u can use external PWM generators, external adc's, you can also use more than one 8051 and communicate them through UART, at expense of speed and problems while troubleshooting. if you have an option, go for PIC.
