MEGA 2560 紅外線

產品介紹:

Arduino Mega 2560是基於ATmega2560的主控開發板。Arduino Mega2560是採用USB介面的核心電路板。具有54路數字輸入輸出，適合需要大量IO介面的設計。處理器核心是ATmega2560,同時具有54路數字輸入/輸出口，16路模擬輸入，4路UART介面，一個16MHz晶體振盪器，一個USB口，一個電源插座，一個ICSP header和一個復位按鈕。板上有支援一個主控板的所有資源。Arduino Mega2560也能相容為Arduino NUO設計的擴充套件板。可以自動選擇3中供電方式：外部直流電源通過電源插座供電；電池連線電源聯結器的GND和VIN引腳；USB介面直流供電。

下方之程式碼主要用途為:

得知遙控器之編碼數值好做進一步的測試

#include <IRremote.h>

int RECV_PIN = 2; // 使用數位腳位2接收紅外線訊號

IRrecv irrecv(RECV_PIN); // 初始化紅外線訊號輸入

decode_results results; // 儲存訊號的結構

int LedMode =0;

void setup()

{

Serial.begin(115200);

irrecv.blink13(true); // 設為true的話，當收到訊號時，腳位13的LED便會閃爍

irrecv.enableIRIn(); // 啟動接收

Serial.println("紅外線訊號輸入啟動接收");

}

void loop() {

if (irrecv.decode(&results)) { // 接收紅外線訊號並解碼

Serial.print("results value is "); // 輸出解碼後的資料

Serial.print(results.value, HEX);

Serial.print(", bits is ");

Serial.print(results.bits);

Serial.print(", decode_type is ");

Serial.println(results.decode_type);

switch (results.value){

case 0xc101E57B:Serial.println("Press 0");LedMode =0;break;

case 0x9716BE3F:Serial.println("Press 1");LedMode =1;break;

}

irrecv.resume(); // 準備接收下一個訊號

}

下方程式碼主要用途為:

用遙控器操控發抒藍芽，MEGA-2560接收要數值轉換成頻率與時間，輸出到蜂鳴器，使其發出聲音。

#include <IRremote.h>

int RECV_PIN = 2; // 使用數位腳位2接收紅外線訊號

IRrecv irrecv(RECV_PIN); // 初始化紅外線訊號輸入

decode_results results; // 儲存訊號的結構

int LedMode = 0;

void setup()

{ pinMode(9, OUTPUT);

Serial.begin(115200);

irrecv.blink13(true); // 設為true的話，當收到訊號時，腳位13的LED便會閃爍

irrecv.enableIRIn(); // 啟動接收

Serial.println("紅外線訊號輸入啟動接收");

}

void loop() {

if (irrecv.decode(&results)) { // 接收紅外線訊號並解碼

Serial.print("results value is "); // 輸出解碼後的資料

Serial.print(results.value, HEX);

Serial.print(", bits is ");

Serial.print(results.bits);

Serial.print(", decode_type is ");

Serial.println(results.decode_type);

switch (results.value) {

case 0xFF6897: Serial.println("Press 0"); LedMode = 0; tone(9, 200, 500); break;

case 0xFF30CF: Serial.println("Press 1"); LedMode = 1; tone(9, 300, 500);break;

case 0xFF18E7: Serial.println("Press 2"); LedMode = 2; tone(9, 400, 500);break;

case 0xFF7A85: Serial.println("Press 3"); LedMode = 3; tone(9, 500, 500);break;

case 0xFF10EF: Serial.println("Press 4"); LedMode = 4; tone(9, 600, 500);break;

case 0xFF38C7: Serial.println("Press 5"); LedMode = 5; tone(9, 700, 500);break;

case 0xFF5AA5: Serial.println("Press 6"); LedMode = 6; tone(9, 800, 500);break;

case 0xFF42BD: Serial.println("Press 7"); LedMode = 7; tone(9, 900, 500);break;

case 0xFF4AB5: Serial.println("Press 8"); LedMode = 8; tone(9, 1000, 500);break;

case 0xFF52AD: Serial.println("Press 9"); LedMode = 9; tone(9, 1100, 500);break;

}

irrecv.resume(); // 準備接收下一個訊號
