How to use Virtual Terminal in Proteus with Arduino Consider the circuit as shown in the following figure:

Now let us simulate the serial communication over UART between the Arduino microcontroller and the Virtual Terminal.

So as can be seen that the data on one terminal can be seen on the other Virtual Terminal.

As shown in the above image that the two Virtual Terminals are connected to each other in such a way that the receiving pin of the one Virtual Terminal is connected to the transmitting pin of the other.

Let us first demonstrate the simple configuration of the Virtual Terminal as shown in the following figure:.

Two pins are for data transmitting and receiving and other two terminals represents the handshaking between the components to be communicated.As shown in the above image that the Virtual Terminal has four pins on it.The Virtual Terminal looks like the one in the following image: The Virtual Terminal in the Proteus is bi-directional which means that it can send and receive data simultaneously.

Thus the Virtual Terminal plays the role while simulating the embedded systems that compliance the serial communication through the Universal Asynchronous Receiver or Transmitter.

It should have come in the reader’s mind that how we can see the data transmitted to or from the microcontroller serial port in the software.

So while writing the code for serial transmission and designing the circuit it is required that the code and design should be tested for serial communication, so that any problem in the code or communication can be resolved before implementing the circuit physically.

which is used to perform serial communication between other hardware used in embedded system that also supports Universal Asynchronous receiving and transmission.

It is important to note here that almost every microcontroller that is used in the embedded system has integrated UART (Universal Asynchronous Receiver Transmitter) on it.

With the help of Virtual Terminal one can easily simulate the serial communication that he / she use in his / her embedded systems.

Virtual Terminal is a very useful tool available in the Proteus.
