microcontroller 8051?

this is pin diagram buddy check through it
i think it is enough for you to understand
if not post your doubt clearly
and i think you must go with interfacing with other devices
do you know micro processor then it is almost similar but controller has less number of inbuilt pins because it is used for only specified equipments
or check here

javI am totally new to practical use of 8051? May I know how and which pin to be connected as input and which pin should be taken as output? Ex. for pick and place robot, I have a camera in front for detecting the presence of the object, and output of the camera should be sent to which pin of the micro controller? and from where the output should be taken?

Dear Jav,

As there are total 4 Ports available in 8051 you can use any port pin as INPUT or OUTPUT but before doing that you must have to check whether your Signal is compatible or not if its not then use external circuitry and interface it with Controller.

again thanks... your post has good info...
