Cara Menggunakan Pemutar MP3 Serial dari CATALEX

Tutorial saya sebelumnya tentang hal ini, hanya satu library yang diperlukan (#include <SoftwareSerial.h>), dan beberapa fungsi mudah yang sudah dijelaskan dalam tutorial sebelumnya:

void sendCommand(int8_t command, int16_t dat) { if (command==CMD_PLAY_WITHFOLDER or command==CMD_PLAY_WITHVOLUME){Serial.print("PLAYING SONG, SLIGHTLY MOVE YOUR HEAD FOR GREAT EFFECT");} delay(20); Send_buf[0] = 0x7e; //starting byte Send_buf[1] = 0xff; //version Send_buf[2] = 0x06; //the number of bytes of the command without starting byte and ending byte Send_buf[3] = command; // Send_buf[4] = 0x00;//0x00 = no feedback, 0x01 = feedback Send_buf[5] = (int8_t)(dat >> 8);//datah Send_buf[6] = (int8_t)(dat); //datal Send_buf[7] = 0xef; //ending byte for(uint8_t i=0; i<8; i++)// { mySerial.write(Send_buf[i]) ;//send bit to serial mp3 } Serial.println(); }

Cara Menggunakan Jarak Jarak Ultrasonik HC-SR04

Tutorial saya sebelumnya tentang hal ini, tidak perlu library, mudah digunakan. Saya hanya mengambil posting HC-SR04 saya sebelumnya dan memasukkannya ke dalam fungsi ini:

long measureDistance(){ long duration, distance; digitalWrite(trigPin, LOW); //PULSE ___|---|___ delayMicroseconds(2); digitalWrite(trigPin, HIGH); delayMicroseconds(10); digitalWrite(trigPin, LOW); duration = pulseIn(echoPin, HIGH); distance = (duration/2) / 29.1; Serial.println("distance:"); Serial.println(distance); return distance; //returns distance in cm }

Cara Menggunakan Keduanya Versi 1: Pemicu Jarak MP3 Sederhana

Pertama, instal library jika Anda belum memilikinya (<SoftwareSerial.h>).

Dalam versi kode ini, jika sesuatu mendekat lebih dari 50cm, maka akan memicu audio MP3. Saya menggunakannya untuk menakut-nakuti rekan kost saya dengan klip "surprise motherfucker" yang sangat keras.

Catatan: Kode .ino lengkap ada di Lampiran Proyek di bawah ini.

void loop() { if(measureDistance()<50){ sendCommand(CMD_PLAY_WITHFOLDER, 0X0203);//play the third song of the second folder delay(1000);//wait to avoid errors } delay(300); }

Cara Menggunakan Keduanya Versi 2 dan Pemicu Jarak MP3 Gangguan

Versi ini tidak peduli dengan jarak, hanya mendeteksi perbedaan antara pembacaan. Jika tiba-tiba memicu karena kesalahan, masukkan nilai yang lebih tinggi di if(gap>20){....... kita perlu mendeklarasikan variabel baru di luar loop. Saya melakukannya di awal kode.

int firstTime=0;//we need to declare firstTime outside the loop long Distance,auxDistance,gap=0; void loop() { Distance=measureDistance(trigPin,echoPin);//measure distance and store gap=abs(Distance-auxDistance);// calculate the difference between now and last reading if(firstTime==0){//necesary for stability things auxDistance=Distance; gap=0; //does it only the first time after play a song to avoid first loop malfuntcion firstTime++; delay(1000); } if(gap>20){ //if distance variation is 20cm sendCommand(CMD_PLAY_WITHFOLDER, 0X0201);//play the first song of the second folder firstTime=0;//avoid errors!!we dont like errors delay(2000); } Serial.print("New Distace:");//debugggggg Serial.print(Distance); Serial.print(" Old Distance: "); Serial.print(auxDistance); Serial.println(gap); delay(300); auxDistance=Distance;//store the value for the if() in the next loop }

Cara Menggunakan Keduanya Versi 3: Dua Sensor Jarak

Dengan dua sensor jarak Anda sebenarnya dapat menebak arah gerakan jadi saya membuat program yang mengatakan "hello" atau "bye" tergantung pada arah gerakan orang.

Pertama, kita definisikan dua pin DIGITAL lain untuk mengontrol HC-SR04 kedua:

#define trigPin 13//for the FIRST distance module #define echoPin 12 #define trigPin2 10//for the SECOND distance module #define echoPin2 9

Variabel baru! Yeah!

long Distance,auxDistance,gap=0; long Distance2,auxDistance2,gap2=0; //new variables

Dalam setup() kita tambahkan deklarasi pin baru kami.

pinMode(trigPin, OUTPUT); pinMode(echoPin, INPUT); pinMode(trigPin2, OUTPUT); pinMode(echoPin2, INPUT);

Kita mengubah fungsi measureDistance(), sekarang fungsi membaca pin dari argumen.

long measureDistance(int trigger,int echo){ long duration, distance; digitalWrite(trigger, LOW); //PULSE ___|---|___ delayMicroseconds(2); digitalWrite(trigger, HIGH); delayMicroseconds(10); digitalWrite(trigger, LOW); duration = pulseIn(echo, HIGH); distance = (duration/2) / 29.1; Serial.println("distance:"); Serial.println(distance); return distance; }

Dalam loop():

void loop() { Distance=measureDistance(trigPin,echoPin);//measure distance1 and store Distance2=measureDistance(trigPin2,echoPin2);//measure distance2 and store gap=abs(Distance-auxDistance);// calculate the difference between now and last reading gap2=abs(Distance2-auxDistance2);// calculate the difference between now and last reading if(firstTime==0){//necesary for stability things auxDistance=Distance; auxDistance2=Distance2; gap=0; gap2=0; //does it only the first time after play a song to avoid first loop malfuntcion firstTime++; delay(2000); } if(gap>20 and gap2<20 ){ //if distance variation is 20cm sendCommand(CMD_PLAY_WITHFOLDER, 0X0201);//play the first song of the second folder firstTime=0;//avoid errors!!we dont like errors Serial.println("RIGHT MOVEMENT DETECTED"); delay(2000); } if(gap2>20 and gap<20){ //if distance variation is 20cm sendCommand(CMD_PLAY_WITHFOLDER, 0X0202);//play the second song of the second folder firstTime=0;//avoid errors!!we dont like errors Serial.println("LEFT MOVEMENT DETECTED"); delay(2000); } Serial.println("\\\\\\\\\\\\\\\\\\\\\\");//debugggggg Serial.print(" New Distace:");//debugggggg Serial.print(Distance); Serial.print(" Old Distance: "); Serial.print(auxDistance); Serial.print(" GAP "); Serial.println(gap); Serial.print("New Distace2:");//debugggggg Serial.print(Distance); Serial.print(" Old Distance2: "); Serial.print(auxDistance); Serial.print(" GAP2 "); Serial.println(gap); Serial.println("\\\\\\\\\\\\\\\\\\\\\\");//debugggggg delay(300); auxDistance=Distance;//store the value for the if() in the next loop auxDistance2=Distance2;//store the value for the if() in the next loop } Disturbance2=0; left=0; right=0; delay(1000);//wait to avoid errors } delay(300); auxDistance=Distance;//store the value for the if() in the next loop auxDistance2=Distance2;//store the value for the if() in the next loop }
