Arduino Serial communication in proteus using Virtual Terminal

we can simulate the arduino serial communication using virtual terminal in the proteus

virtual terminal in proteus is located at logo which highlighted as Instruments and can be located

in the instruments we can choose the virtual instrument

we can select the serial transmission characteristics such as baud rate, parity... etc



code which is dumped into Arduino is

const int pin = 13;
void setup()
{
pinMode(pin,OUTPUT);
Serial.begin(9600);
Serial.println("enter y to ON and n to OFF");
}

void loop()
{
while(!Serial.available())
{
//wait until user enters the data
}

if(Serial.available())
{
char input = Serial.read();
switch(input)
{
case 'y':
Serial.println("you entered y led ON");
digitalWrite(pin,HIGH);
break;
case 'n':
Serial.println("you entered n led is OFF");
digitalWrite(pin,LOW);
break;
default:
Serial.println("you entered wrong character");
}//end of switch
}//end of If

}//end of loop


Arduino Relay driver using optocoupler in Proteus

In relay On condition


In relay Off condition


Arduino Code is


const int pin =13;

void setup(){
pinMode(pin,OUTPUT);
Serial.begin(9600);
Serial.println("Please enter a char");
}

void loop(){
Serial.println("Please enter y to ON and n to OFF led");
while(!Serial.available())
{
//wait until user enters the data
}

char input;
if(Serial.available())
{
Serial.println(input = Serial.read());
if(input == 'y'){
Serial.println("you entered y led is ON");
digitalWrite(pin,HIGH);
}
else if(input == 'n'){
Serial.println("you entered n led is OFF");
digitalWrite(pin,LOW);
}
else{
Serial.println("you entered a wrong character");
}
}
}
