Question

Develop a simple code to read a digital pin in the GPIO set of pins in your micro-controller and set another digital pin to output high, if the read pin is also high.

Answer 1

Code:

int a=11;
int b=7;
int v=0;
void setup() {
pinMode(a,INPUT);
pinMode(b,OUTPUT);
Serial.begin(9600);

}

void loop() {
int v=digitalRead(a);// Reads digital pin 'a' i.e 11
  
if(v==1)
{
digitalWrite(b,HIGH);}
else if(v==0)
{
digitalWrite(b,LOW);
//delay(1000);
}

}
