Question

What case is called serialEvent() interrupt?

1) Serial port shuts down.
2) When data is sent from the serial port.
3) When data comes from the serial port.
4) When the voltage is applied to the Arduino.

Answer 1

The serialEvent() interrupt in Arduino is called when data comes from the serial port.

Step-by-step explanation:

The case that is called serialEvent() interrupt is when data comes from the serial port. When data is received from the serial port, the serialEvent() function is automatically called in Arduino, allowing you to write code to handle the received data.
