This example demonstrates string-based communication from the Arduino board to the computer using a call-and-response (handshaking) method. 本例展示了 Arduino 和电脑间的,基于字符串的调用和应答(握手)通信。 The sketch sends an ASCII string on startup and repeats that until it gets a serial respo...

For example, the following: int b = 79; Serial.print(b); prints the string 79 to the Serial Monitor window. The following little application will print the message every two seconds: int i = 0; void setup() { Serial.begin(9600); } void loop() { Serial.print(" hey there, just ...
