Now, the personal computer which you are using is working with the software. The software is the one to have written the operation order of the hardware (the personal computer). It is possible to make do the various operation to the hardware when making memorize this procedure in the memory and making execute it in the order. It is possible to make do the operation which is different with the same hardware by changing the software. It is very convenient.
On these pages, I will introduce the electronic circuits making which used the PIC(Peripheral Interface Controller) which is the one-chip microprocessor.
I will make this page for the beginner of PIC including me.
