यदि "पिन2" को "1011" भेजा जाता है जहां 1 5V है और 0 0V है तो "पिन1" का आउटपुट क्या है?
What is the output of “pin1” if “pin2” is sent “1011” where 1 is 5V and 0 is 0V?
int pin1 = 12;
int pin2 = 11;
void setup() {
pinMode(pin1, OUTPUT);
pinMode(pin2, INPUT);
Serial.begin(9600);
}
void loop() {
if(digitalRead(pin2)==1) {
digitalWrite(pin1,LOW);
}
else if(digitalRead(pin2)==0) {
digitalWrite(pin1,HIGH);
}
}
A)
B)
C)
D)
Explanation:
The given Arduino code reads the input from pin2 and changes the output on pin1 based on whether the value from pin2 is HIGH (1) or LOW (0).
Explanation:
- For each bit in
1011sent to pin2:- 1 means pin2 is HIGH → pin1 is set to LOW.
- 0 means pin2 is LOW → pin1 is set to HIGH.
Thus, for the sequence 1011:
- pin2 (1) → pin1 = LOW
- pin2 (0) → pin1 = HIGH
- pin2 (1) → pin1 = LOW
- pin2 (1) → pin1 = LOW
The resulting output for pin1 will be 0100.
Final Answer:
(B) 0100
