Data communication between electronic devices is inevitable in many electronic projects and brings a lot of advantages to your project i.e. connecting your microcontroller to PC and monitor data on a large colorful display instead of small monochrome LCD. When talking about connecting a device to PC, the most obvious way of communicating is USB port. But transmitting data over USB requires lots of programming. Another easy way is Serial Port (aka COM) and RS232 protocol that only needs a tiny electronic circuit to convert voltage levels and a little programming. So I made an RSS232-TTL UART adapter and published here to uses in all of my projects. But I faced a new problem, new motherboards and laptops have no COM port. Then I decided to make a USB-TTL UART adapter using famous FT232 IC for my projects. It works very well, but long wires from devices to PC are annoying me. Is it possible to have the serial port on the air like wireless mice and keyboards? Of course, it can be done using lovely WiFi module ESP8266, and by using WiFi you have not to make a dongle yourself and also you can have a serial port over the internet. Wow, I just wanted a wireless serial port, now I also have a serial port over the web. That's very exciting.

The Serial Connection Close-up of 9-pin and 25-pin serial connectors The external connector for a serial port can be either 9 pins or 25 pins. Originally, the primary use of a serial port was to connect a modem to your computer.
