I am trying to connect a df player with an ultrasonic sensor so that once a hand is put near, a song plays from the df player. I've already connected the components properly and put the micro sd card(16GB) with the music in the df player.
I am using an Arduino UNO.
I used the files from this website:
#include <SoftwareSerial.h>
#include <DFPlayer_Mini_Mp3.h>
//√ ¿Ω∆ƒ ºæº≠ «…º≥¡§
int trigPin = 9;
int echoPin = 8;
void setup () {
Serial.begin (9600);
mp3_set_serial (Serial); // DFPlayer-mini mp3 module Ω√∏ÆæÛ ºº∆√
delay(1); // ∫º∑˝¿ª Setup «œ±‚ ¿ß«— delay
mp3_set_volume (30); // ∫º∑˝ 0~30
//√ ¿Ω∆ƒ ºæº≠ «…º≥¡§
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
}
void loop () {
float duration, distance;
digitalWrite(trigPin, HIGH);
delay(10);
digitalWrite(trigPin, LOW);
// ¿Âæ÷π∞∞˙¿« ∞≈∏Æ∞˪Í
duration = pulseIn(echoPin, HIGH);
distance = ((float)(340 * duration) / 10000) / 2;
delay(100);
if(distance < 50) //¿Âæ÷π∞¿Ã 50cm ¿Ã≥ª¿œ∂ß
{
mp3_play(99); //æ»≥Á«œººø‰... mp3 (0099.mp3) ∆ƒ¿œ «√∑π¿Ã
delay(7000);
}
}
Then there is another folder with a bunch of codes; I attached it as well.
I am not sure of what I should do after pasting this code. I simply tried adding a zip file with the files attached below, but it shows this error message:
