What is the outcome of the following Arduino code ?

निम्नलिखित अरुडिनो कोड का परिणाम क्या है?

void setup() {
Serial.begin(9600);
}
void setup() {
Serial.write(20);
}

Send a signal to pin 20 on the Arduino board

Send a octal number of 20 through the Serial pins

Send a byte with value 20 through the Serial pins

Send a hexadecimal number of 20 through the Serial pins

Explanation

Let's analyze the provided Arduino code:

void setup() {
  Serial.begin(9600);
}

void setup() {
  Serial.write(20);
}

Serial.begin(9600);:
- This initializes serial communication at a baud rate of 9600 bits per second. It prepares the Arduino to send and receive data over the serial connection.
Serial.write(20);:
- Serial.write() sends data as bytes over the serial connection. It takes a single byte as an argument and sends it.
- The argument 20 is a decimal value, which is equivalent to 0x14 in hexadecimal and 24 in binary.
- The write() function sends this byte (value 20) to the serial port.

The code will send a byte with the value 20 (in decimal) through the serial connection.
- This is not a string or number in octal/hexadecimal format, but the actual byte value 20.
