Hello Mr. Arif Deshmukh,

Let me apologize for the other forum members unprofessional responses. I am now sure why they like to give childlike answers. Anyway, I would say the PIC processor is the easiest to learn because it only has 35 instructions total. I have used the PIC 16C54 and 16F84 IC's a lot and found them to be a very good IC's. There is an awful lot of support for the PIC on the Internet so I guess that would assist you in learning it.

Regards,

Charles Bannister
