关于arduino的一个问题
红外遥控代码 代码是这样
#include <IRremote.h>//包含红外库
int RECV_PIN = 11;//端口声明
IRrecv irrecv(RECV_PIN);
decode_results results;//结构声明
unsigned long last = millis();
long left_turn = 0x00FFA25D;//按键1 十进制
long run_car = 0x00FF629D;//按键2 十进制
long right_turn = 0x00FFE21D;//按键3 十进制
long stop_car = 0x00FF02FD;//按键5 十进制
long left_car = 0x00FF22DD;//按键4 十进制
long right_car = 0x00FFC23D;//按键6 十进制
long back_car = 0x00FFA857;//按键8 十进制

但是串口是这样
