红外遥控+数码管显示+LED灯

wolfcolorful 发表于 2016-7-18 17:14:41

在论坛中学了不少时间了，自己做了一个小综合的实验：遥控器控制8个LED，“0”表示全灭，“1”表示亮第一个，“2”表示亮前两个，……，数码管上做同步显示。
参考以下教程：Arduino入门教程--第二十课--红外遥控器介绍；Arduino入门教程--第十八课--Arduino驱动数码管；Arduino入门教程--第一课--板载LED闪烁实验……等。
物料：Arduino Mega 2560板——1块，8段数码管（共阴极）——1个，LED——8个，1838红外发射头——1个，220欧电阻——9个，杜邦线——若干。
下面是硬件连接图：

#include <IRremote.h>// 使用IRRemote函数库
long int IR_button;
String Button_value;
int i;

const int irReceiverPin = 2;// 红外接收器的 OUTPUT 引脚接在 PIN0 接口定义irReceiverPin变量为PIN2接口

IRrecv irrecv(irReceiverPin); // 设置irReceiverPin定义的端口为红外信号接收端口
decode_results results; // 定义results变量为红外结果存放位置

void setup()
{
Serial.begin(9600); // 开启串口，波特率为9600
irrecv.enableIRIn(); // 启动红外解码
for(i=3;i<=21;i++) pinMode(i,OUTPUT);
}

void loop()
{
if (irrecv.decode(&results))
{ // 解码成功，把数据放入results变量中
// 把数据输入到串口
//Serial.print("irCode: ");
//Serial.print(results.value, HEX); // 显示红外编码
//Serial.print(",bits: ");
//Serial.println(results.bits); // 显示红外编码位数
irrecv.resume(); // 继续等待接收下一组信号
IR_button=results.value;
//Serial.println(IR_button);
switch (IR_button)

见笑，见笑！
本业是做机械的，跟着论坛的前辈们照猫画虎，略有所得吧。
