Question

While taking the input from the user in Arduino, which of these function is used in Sketch?

1) Serial.print
2) Serial.println
3) Serial.available
4) None of the other

Answer 1

The function to take input from the user in an Arduino sketch is Serial.available(). It checks if there is data available to read from the serial buffer.

Step-by-step explanation:

To take input from the user in an Arduino sketch, the correct function to use is Serial.available(). This function is essential when you're expecting to receive data over the serial port, as it checks if data is available to read. When Serial.available() returns a number more than 0, it means that there is some data in the serial buffer that can be read, which can then be retrieved using Serial.read() or other related functions. On the other hand, the functions Serial.print() and Serial.println() are used for sending data from the Arduino to the connected computer over the serial port
