In this series of tutorials we are going to cover all about avr microcontroller from basic to advance from doing any project point of view so stay tuned to my blog for updated content. {CONTENT IS UPDATED EVERY SATURDAY} AVR is advance virtual RISC microcontroller. So, now what is RISC.It's reduced instruction set computing. The microcontrollers are generally either RISC based or CISC based.CISC is complex instruction set computing.Lets understand RISC and CISC by taking an example. example of CISC is scientific calculators that we use in engineering designed to perform all the arithmetic and logical operation and also various other operation like calculating log,solution of linear equation,exp etc. example of RISC is the buisness calculators that we generally see in any stores that are designed to perform only some specific operations that are most commonly used like +,-,*,/ etc.These are derived from the scientific calculator thats why called REDUCED. The AVR is a RISC...
