Ajay, because I want to have multiple RFID in the future so I think the best way is to have extra com port. Since microcontroller only have 1 serial port.

Also how do i connect the prototype area?

I am not clear with "prototype area". Can you be more clear on what you specifying.

Oh sorry sorry, I mean the prototype area on my development board. I am able to implement LED on the prototype area on the development board.

But now the problem is I want to implement switch on it. But still cannot do. Hope anyone can help.

Hey, I think your site might be having browser compatibility issues. When I look at your website in Ie, it looks fine but when opening in Internet Explorer, it has some overlapping. I just wanted to give you a quick heads up! Other then that, very good blog! https://onanadiete.ru/alpha-numeric-reasoning-questions-and-answers-pdf.pdf alpha numeric reasoning questions and answers pdf alpha numeric reasoning questions and answers pdf
