A timing music player allows us to relax with a piece of music on a designated time or remind us it is time to do something. Today we are going to make a timing music player with Arduino UNO.

1 X Freaduino UNO Rev2.2 MB_EFUNO

1 X Mp3 Module

2 X Octopus Real-time Clock

1 X Micro SD Card

1 X Speaker

Let's take a look at our final work of hardware connection first.

Plug your components together according to the table below.

Finnally, connect Mp3 Module with your speaker. Now all connection are completed!

It is inspired by JQ6500-24SS MP3 chipset of Jiaqiang Electronics. It supports SD cards for FAT16, FAT32 file systems and SPI Flash updates via PC. With some very simple serial commands to control music playback, it owns the characteristics of easy operation and stable performance. Additionally, with an external headphone (PH) and an external speaker (SP), the MP3 Module provides more interfaces and utilities.

This is a clock module which can achieve counting for year, month, day, hour by using the DS1307 clock chip.This chip has lots of merits. For example, low power supply, with 56 bytes of non-volatile RAM clock calendar and BCD code real-time clock chip, transmit address and data via a two-wire bidirectional serial bus, provide time information in detail as well as other information, automatically adjust the number of days in each month, etc.. And more surprisingly, the chip has also equipped with the function of leap year compensation. It has a built-in power-sense circuit with the function of brownout detection and battery switching.

First of all, we have to upload 2 package files: "DS1307RTC" and "Time".

Next click "", choose "SetTime", and then upload your code. Set your computer system time to be time showed within Octopus Real-time Clock.

"Jul", "Aug", "Sep", "Oct", "Nov", "Dec"
};

tmElements_t tm;

void setup() {
bool parse=false;
bool config=false;

// get the date and time the compiler was run
if (getDate(__DATE__) && getTime(__TIME__)) {
parse = true;
// and configure the RTC with this info
if (RTC.write(tm)) {
config = true;
}
}

Serial.begin(9600);
while (!Serial) ; // wait for Arduino Serial Monitor
delay(200);
if (parse && config) {
Serial.print("DS1307 configured Time=");
Serial.print(__TIME__);
Serial.print(", Date=");
Serial.println(__DATE__);
} else if (parse) {
Serial.println("DS1307 Communication Error :-{");
Serial.println("Please check your circuitry");
} else {
Serial.print("Could not parse info from the compiler, Time=\"");
Serial.print(__TIME__);
Serial.print("\", Date=\"");
Serial.print(__DATE__);
Serial.println("\"");
}
}

void loop() {
}

bool getTime(const char *str)
{
int Hour, Min, Sec;

if (sscanf(str, "%d:%d:%d", &Hour, &Min, &Sec) != 3) return false;
tm.Hour = Hour;
tm.Minute = Min;
tm.Second = Sec;
return true;
}

bool getDate(const char *str)
{
char Month[12];
int Day, Year;
uint8_t monthIndex;

if (sscanf(str, "%s %d %d", Month, &Day, &Year) != 3) return false;
for (monthIndex = 0; monthIndex < 12; monthIndex++) {
if (strcmp(Month, monthName[monthIndex]) == 0) break;
}
if (monthIndex >= 12) return false;
tm.Day = Day;
tm.Month = monthIndex + 1;
tm.Year = CalendarYrToTm(Year);
return true;
}

 commands have to be written into code in the format of array. Send these commands through serial port so as to achieve the control of Mp3 Module.

unsigned char play[6] = {0x7E, 0x04, 0x03, 0x00, 0x01, 0xEF}; //play bofang

unsigned char SC_SD[5] = {0x7E, 0x03, 0x09, 0x01, 0xEF};//set music effects

unsigned char play_mode[5] = {0x7E, 0x03, 0x11, 0x00, 0xEF};//set play mode

unsigned char pause[4] = {0x7E, 0x02, 0x0E, 0xEF}; //stop

unsigned char next[4] = {0x7E, 0x02, 0x01, 0xEF}; //next one

SoftwareSerial mySerial(2, 3);

In the array, there are 3 values relatively for: the hour pin in the beginning, the minute pin and the end minute pin in the play.

unsigned int time1[3] = {9, 0, 5}; //start at 9:00 and end at 9:05.

Judge if time is between 9:00 and 9:05. If it is, then play music.

if (TimeHour == time1[0] && TimeMinute >= time1[1] && TimeMinute < time1[2] ) //9:00

{

if (MP3status == 0)

{

mySerial.write(next, 4);

delay(5);

mySerial.write(play, 6); //start play

delay(10);

Serial.println("The first start");

MP3status = 1;

}

else

Serial.println("The first start");

}

Judge if time is 9:05. If it is, stop playing music. 

if (TimeHour == time1[0] && TimeMinute == time1[2] )

{

if (MP3status == 1)

{

mySerial.write(pause, 4); //stop play

delay(10);

Serial.println("The first one is over");

MP3status = 0;

}

else

Serial.println("The first one is over");

}
