main component of embedded system is Micrcocontroller

important concept :

Embedded system :

Main component in Embedded system is microcontroller .

What is PIC microcontroller ?

Is small computer with CPU, ram, rom.

Why do you prefer to use PIC microcontroller ?

Let me ask you : if your project  is very big  that mean number of hardware component is huge .

So any mistake in any component ,project will not.

So to reduce number of component of project and more easier to discovery any error ,use microcontroller

Because PIC microcontroller use code to burn ,so you can debug ,update code easily .

I prefer PIC  microcontroller for reason that it is easy in programming .

Note : deal with PIC microcontroller is low voltage about 6 voltage ,so if you want to run device with more voltage ,will need for  relay.
