serialEvent()

Descrição

Chamada quando dados estão disponíveis no buffer serial. Use Serial.read(), Serial.readBytes(), Serial.readBytesUntil(), Serial.readString(), or Serial.readStringUntil() para ler esses dados.

※ Notas e Advertências:

Serial functions are not only used for the communication between an Arduino board and Serial Monitor of Arduino IDE but also used for the communication between:

  • An Arduino board and other Arduino board
  • An Arduino board and other sensors/devices
  • An Arduino board and computer (any Serial software on computer)
