ATmega8 and Arduino UART

How to establish UART communication between ATmega8 and Arduino Uno?

Here we are going to establish a communication between an ATmega8 microcontroller and Arduino Uno. The communication established here is UART (Universal Asynchronous Receiver Transmitter) type. It’s serial communication. By this serial communication data can be shared between two controllers, which is a required in various embedded system applications. In embedded systems we must have basic knowledge about system communications, so …
