Hi,

Which one is correct?

1. [FONT=&quot]Design and Implementation of Digital Thermo-Controller by using 8951 Microcontroller.

2. [/FONT][FONT=&quot]Design and Implementation of Digital Thermo-Controller with using 8951 Microcontroller.

3. [/FONT][FONT=&quot]Design and Implementation of Digital Thermo-Controller by use of 8951 Microcontroller.

Thanks in advance.

Welcome to the forum, mo_soroush

The simplest sentence seems to me to be:

[FONT=&quot]Design and Implementation of Digital Thermo-Controller using 8951 Microcontroller.[/FONT]

I assume, from the absence of articles and finite verb, that this is a title.
