/*Reading a serial ASCII-encoded string.This sketch demonstrates the Serial parseInt() function.It looks for an ASCII string of comma-separated values.It parses them into ints, and uses those to fade an RGB LED.Circuit: Common-Cathode RGB LED wired like so:- red anode: digital pin 3 th...
Serial.read(); 参数 None 返回 返回串口缓存中第一个可读字节,当没有可读数据时返回-1,整数类型。 示例 charcomchar;voidsetup(){ Serial.begin(9600);while(Serial.read()>=0){}/ /clear serialbuffer }voidloop(){// read data from serial portwhile(Serial.available()>0){ comchar = Serial.read...
