In this project I will show you how you can make an Arduino Touch Screen MP3 Music Player and Alarm Clock. You can watch the following video or read the written tutorial below.
OverviewThe home screen features a big clock, date and temperature information, as well as, two buttons for the Music Player and the Alarm Clock.
If we enter the Music Player we can start playing the music by pressing the big “Play” button in the middle of the screen. Right beside it, there are two more buttons, for playing the previous or the next song.
Above these buttons there is the song progress bar, and at the bottom of the screen we have a volume bar and two buttons for decreasing and increasing the volume. In the upper right corner there is a clock and on the left side is the “Menu” button which brings us back to the home screen.
On the other hand, if we enter the Alarm Clock we can set an alarm by using the two buttons for setting the hours and the minutes.
When the alarm will be activated, a song will start playing at a higher volume, and it will keep playing until we press the “Dismiss” button.
How It WorksNow let’s take a look how this device works. It uses an Arduino Mega board and a 3.2” TFT touch screen with a suitable shield for connecting the screen with the Arduino Board. For playing the music, it uses the BY8001 MP3 Player module and for the alarm clock it uses the DS3231 Real Time Clock module.

Circuit SchematicsHere’s the circuit schematics of this project:
We can note here that the TFT shield is blocking the free pins of the Arduino board so we need to make a custom-made pin headers which we will be able to insert them between the shield and the Arduino.
Also note that for powering the Arduino we need to solder additional pin header to the 5 V pin on the shield, as the shield already uses all Arduino VCC pins.
Once we connect everything together we can proceed with programing the Arduino. However, before we continue I would to suggest you to check my previous detailed tutorials for the TFT touch screen and the DS3231 Real Time Clock module. And as for the MP3 Player module I will give it a quick explanation here in this article.
BY8001-16P MP3 Player ModuleThe BY8001-16P is a MP3 module which works with MicroSD cards and supports MP3 and WAV audio format files. The module has a built-in 3W power amplifier and can directly drive a single 3W speaker.
The MP3 Player module can be button controlled using the 5 input pins or using a microcontroller via the serial communication.
Note here that the serial port pins of the module work at 3.3V so the RX pin of the module needs to be connected through a 1K resistor to the Arduino TX pin. Also note the 3 ports A, B and C which are used for selecting the control modes. For controlling the module using a microcontroller the 3 resistors at these pads need to be removed. The pins number 6 and 7 can be used for directly connecting low power speakers or the pins number 4 and 5 if using external amplifier.
As for the Arduino part the easiest way is to use the BY8001 library which can be downloaded from GitHub. If we open some of its demo examples we can see how it works. So after initializing the module in the setup section, we can use any of the custom-made functions for controlling the module.
Source codeNow we are ready to take a look at the code of this Arduino Touch Screen MP3 Screen Music Player and Alarm Clock. As the code is a bit longer, for better understanding, I will post the source code of the program in sections with description for each section. And at the end of this article I will post the complete source code.
So, first we need to include the libraries for the TFT touch screen, the BY8001-16P MP3 Player and the DS3231 Real Time Clock module, as well as, the library for the serial communication. Then we have to create the appropriate objects and define some variables needed for the program.

String currentClock, currentHours, currentMinutes, currentSeconds, currentDate;
String timeString, hoursString, minutesString, secondsString, hoursS, minutesS, secondsS, dateS;Code language: PHP (php)We can note here the defining of the bitmaps. Some of the buttons of the program are actually images which are converted into bitmaps using the ImageConverter565 tool which comes with the TFT library.
So, these “.c” files needs to be included in the directory of the code file so that they load when launching the sketch. Here you can download these images and “.c” files.
In the setup section after initializing the objects, we call drawHomeScreen() custom function which draws all the graphics of the home screen. Also here we set the initial values of some of the variables, like the playStatus, currentTemp and Date, the initial value of the volume and so on.
void setup() {
myGLCD.InitLCD();
myGLCD.clrScr();
myTouch.InitTouch();
myTouch.setPrecision(PREC_MEDIUM);
rtc.begin();
Serial.begin(9600);
mp3Serial.begin(9600);
mp3.setup(mp3Serial);
delay(800);
drawHomeScreen();
currentPage = '0';
playStatus = '0';
mp3.setVolume(15);
delay(100);
currentTemperature = rtc.getTemp();
currentDate = rtc.getDateStr();
currentClock = rtc.getTimeStr();
timeString = rtc.getTimeStr();
currentHours = timeString.substring(0, 2);
currentMinutes = timeString.substring(3, 5);
currentSeconds = timeString.substring(6, 8);
}Code language: JavaScript (javascript)Next is the loop section. The first if statement is true as we have set the currentPage variable to be 0 which indicates that we are on the home screen. Here with the next if statement we check whether we have a change in the clock and this happens each second. Now as we are using the seven segment font of the TFT libraries, which doesn’t support any character except numbers, we have to extract only the numbers from the string that is coming with the getTimeStr() function for reading the clock from the DS3231 RTC module.
So using the substring() function we get the hours, the minutes and seconds into separate variables and print them each time a changed has happened in the seconds, the minutes or the hours.
As for the date and temperature, similar, we check whether there is a change compared to the previous state.
void loop() {
if (currentPage == '0') {
if ( currentClock != rtc.getTimeStr()) {
timeString = rtc.getTimeStr();
hoursS = timeString.substring(0, 2);
minutesS = timeString.substring(3, 5);
secondsS = timeString.substring(6, 8);
myGLCD.setFont(SevenSegNumFont);
myGLCD.setColor(0, 255, 0);
myGLCD.print(secondsS, 224, 50);
if ( currentMinutes != minutesS ) {
myGLCD.print(minutesS, 128, 50);
currentMinutes = minutesS;
}
if ( currentHours != hoursS ) {
myGLCD.print(hoursS, 32, 50);
currentHours = hoursS;
}
dateS = rtc.getDateStr();
delay(10);
if ( currentDate != dateS){
myGLCD.setColor(255, 255, 255);
myGLCD.setFont(BigFont);
myGLCD.print(rtc.getDateStr(), 153, 7);
}
temperature = rtc.getTemp();
delay(10);
if ( currentTemperature != temperature ){
myGLCD.setColor(255, 255, 255);
myGLCD.setFont(BigFont);
myGLCD.printNumI(temperature, 39, 7);
currentTemperature = temperature;
}
delay(10);
currentClock = rtc.getTimeStr();
}Code language: PHP (php)Next, using the myTouch.dataAvailable() function we check whether we have touched the screen and also check whether it’s the Music Player or the Alarm button. So if that’s the Music Player button, first we call the drawFrame() custom function which draws a red circle around the button indicating that the button has been pressed. Also this custom function has a while loop which hold the program stacked until we release the button. Right after that, we set the currentPage variable to 1, clear the screen and call the drawMusicPlayerScreen() custom function which draws all the graphics of the Music Player screen. Similar, if we press the Alarm button we, we set the currentPage variable to 2 and clear the screen.
if (myTouch.dataAvailable()) {
myTouch.read();
x = myTouch.getX();
y = myTouch.getY();
if ((x >= 55) && (x <= 120) && (y >= 125) && (y <= 190)) {
drawFrame(87, 157, 33);
currentPage = '1';
myGLCD.clrScr();
delay(100);
drawMusicPlayerScreen();
delay(100);
}
if ((x >= 195) && (x <= 260) && (y >= 125) && (y <= 190)) {
drawFrame(227, 160, 29);
currentPage = '2';
myGLCD.clrScr();
}
}Code language: JavaScript (javascript)Next, let’s see what happens in the Music Player screen. Here we are constantly checking whether we have touched the screen. If we touch the Play button and the current playStatus variable is 0, we will call the mp3.playTrackFromFolder() function which will start playing the first song from the MicroSD card. At the same time, we call the drawPauseButton() custom function which draws the Pause button and set the playStatus variable to 2. Using the next two if statements, depending on the playStatues variable, we toggle between playing and pausing the song.
if (currentPage == '1') {
if (myTouch.dataAvailable()) {
myTouch.read();
x = myTouch.getX();
y = myTouch.getY();
if ((x >= 116) && (x <= 204) && (y >= 77) && (y <= 165)) {
if (playStatus == '0') {
drawFrame(159, 121, 42);
drawPauseButton();
mp3.playTrackFromFolder(00, 001);
delay(100);
playStatus = '2';
return;
}
if (playStatus == '1') {
drawFrame(159, 121, 42);
drawPauseButton();
mp3.play();
delay(100);
playStatus = '2';
return;
}
if (playStatus == '2') {
drawFrame(159, 121, 42);
drawPlayButton();
mp3.pause();
delay(100);
playStatus = '1';
return;
}
}Code language: JavaScript (javascript)In similar way, for each pressed button we call the appropriate functions for playing the previous or the next track, decrease or increase the volume, as well as the “Menu” button which brings us back to the home screen.
if ((x >= 45) && (x <= 95) && (y >= 97) && (y <= 147)) {
drawFrame(70, 121, 26);
mp3.previousTrack();
delay(100);
drawTrackBar();
}
if ((x >= 227) && (x <= 277) && (y >= 97) && (y <= 147)) {
drawFrame(252, 122, 26);
mp3.nextTrack();
delay(100);
drawTrackBar();
}
if ((x >= 35) && (x <= 75) && (y >= 165) && (y <= 209)) {
drawUnderline(45, 205, 65, 205);
if (iV >= 0 & iV <= 30) {
iV--;
drawVolume(iV);
}
mp3.decreaseVolume();
delay(100);
}
if ((x >= 230) && (x <= 280) && (y >= 165) && (y <= 209)) {
drawUnderline(235, 205, 275, 205);
if (iV >= 0 & iV <= 30) {
iV++;
drawVolume(iV);
}
mp3.increaseVolume();
delay(100);
}
if ((x >= 0) && (x <= 75) && (y >= 0) && (y <= 30)) {
myGLCD.clrScr();
drawHomeScreen();
currentPage = '0';
return;
}Code language: JavaScript (javascript)The next if statement is used for updating the track progress bar.
// Updates the track bar
if (playStatus == '1' || playStatus == '2') {
trackPlayTime();
}
So if the music is playing we call the trackPlayTime() custom function which using some of the Music Player library functions, like the mp3.getElapsedTrackPlaybackTime(), calculates and prints the elapsed and remained time as well as the track progress bar graphics. Using the printClock() custom function we print the clock in the upper right corner.
void trackPlayTime() {
totalTime = mp3.getTotalTrackPlaybackTime();
delay(10);
elapsedTime = mp3.getElapsedTrackPlaybackTime();
delay(10);
minutes = (int)elapsedTime / 60;
seconds = (((float)elapsedTime / 60) - minutes) * 60;
playback = totalTime - elapsedTime;
minutesR = (int)playback / 60;
secondsR = (((float)playback / 60) - minutesR) * 60;
myGLCD.setFont(SmallFont);
myGLCD.setColor(255, 255, 255);
myGLCD.printNumI(minutes, 8, 48);
myGLCD.print(":", 16, 48);
myGLCD.printNumI((int)seconds, 24, 48, 2, '0');
myGLCD.print("-", 276, 48);
myGLCD.printNumI(minutesR, 284, 48);
myGLCD.print(":", 292, 48);
myGLCD.printNumI((int)secondsR, 300, 48, 2, '0');
int trackBarX = map(elapsedTime, 0, totalTime, 0, 224);
myGLCD.setColor(255, 0, 0);
myGLCD.fillRect (48, 50, 48 + trackBarX, 50 + 8);
if (totalTime == elapsedTime) {
mp3.nextTrack();
delay(30);
myGLCD.setColor(255, 255, 255);
myGLCD.fillRect (48, 50, 48 + 224, 50 + 8);
}
}Code language: PHP (php)Next is the Alarm Clock screen. Here first we draw all the graphics, the clock, the text and the buttons and also set the variable alarmNotSet to be true so that we can enter the next while loop. Here using the two buttons, H and M, we set the alarm and once we click the “Set” button the value of the alarm is stored into the alarmString variable.
if (currentPage == '2') {
myGLCD.setFont(BigFont);
myGLCD.setColor(255, 255, 255);
myGLCD.print("MENU", 5, 5);
myGLCD.print("Set Alarm", CENTER, 20);
myGLCD.setColor(0, 255, 0);
myGLCD.fillCircle (112, 65, 4);
myGLCD.setColor(0, 255, 0);
myGLCD.fillCircle (112, 85, 4);
myGLCD.setFont(SevenSegNumFont);
myGLCD.setColor(0, 255, 0);
myGLCD.printNumI(aHours, 32, 50, 2, '0');
myGLCD.printNumI(aMinutes, 128, 50, 2, '0');
myGLCD.setColor(255, 255, 255);
myGLCD.drawRoundRect (42, 115, 82, 145);
myGLCD.drawRoundRect (138, 115, 178, 145);
myGLCD.setFont(BigFont);
myGLCD.print("H", 54, 122);
myGLCD.print("M", 150, 122);
myGLCD.drawRoundRect (215, 60, 303, 90);
myGLCD.print("SET", 236, 67);
myGLCD.drawRoundRect (215, 115, 303, 145);
myGLCD.print("CLEAR", 220, 122);
alarmNotSet = true;
while (alarmNotSet){
if (myTouch.dataAvailable()) {
myTouch.read();
x = myTouch.getX();
y = myTouch.getY();
if ((x >= 42) && (x <= 82) && (y >= 115) && (y <= 145)) {
drawRectFrame(42, 115, 82, 145);
aHours++;
if(aHours >=24){
aHours = 0;
}
myGLCD.setFont(SevenSegNumFont);
myGLCD.setColor(0, 255, 0);
myGLCD.printNumI(aHours, 32, 50, 2, '0');
}
if ((x >= 138) && (x <= 178) && (y >= 115) && (y <= 145)) {
drawRectFrame(138, 115, 178, 145);
aMinutes++;
if(aMinutes >=60){
aMinutes = 0;
}
myGLCD.setFont(SevenSegNumFont);
myGLCD.setColor(0, 255, 0);
myGLCD.printNumI(aMinutes, 128, 50, 2, '0');
}
if ((x >= 215) && (x <= 303) && (y >= 60) && (y <= 80)) {
drawRectFrame(215, 60, 303, 90);
if (aHours < 10 && aMinutes < 10){
alarmString = "0"+(String)aHours + ":" + "0"+ (String)aMinutes + ":" + "00";
}
else if (aHours < 10 && aMinutes > 9){
alarmString = "0"+(String)aHours + ":" + (String)aMinutes + ":" + "00";
}
else if (aHours > 9 && aMinutes < 10){
alarmString = (String)aHours + ":" + "0"+ (String)aMinutes + ":" + "00";
}
else {
alarmString = (String)aHours + ":" + (String)aMinutes + ":" + "00";
}
myGLCD.setFont(BigFont);
myGLCD.print("Alarm set for:", CENTER, 165);
myGLCD.print(alarmString, CENTER, 191);
}
if ((x >= 215) && (x <= 303) && (y >= 115) && (y <= 145)) {
drawRectFrame(215, 115, 303, 145);
alarmString="";
myGLCD.setColor(0, 0, 0);
myGLCD.fillRect(45, 165, 275, 210);
}
if ((x >= 0) && (x <= 75) && (y >= 0) && (y <= 30)) {
alarmNotSet = false;
currentPage = '0';
myGLCD.clrScr();
drawHomeScreen();
}
}
}
}Code language: JavaScript (javascript)Note here that we need to adjust this string to have the same form as the string that we get from the getTimeString() function. In this way we will be able to compare them and activate the alarm when the clock will reach that same value or time.
If we press the clear button we will clear the alarmString and if we press the menu button it will get us out of the while loop and send back to the home screen.
For activating the alarm, we check whether the alarm has been set and if the alarm matches with the clock, the first song on the MicroSD card will start playing at a higher volume. Also we will draw all the graphics together with the “Dismiss” button and set the alarmOn variable to true. This will get us into the next while loop which will enable to song to keep playing until we press the “Dismiss” button.
if (alarmNotSet == false) {
if (alarmString == rtc.getTimeStr()){

myGLCD.print(alarmString, CENTER, 114);

}Code language: PHP (php)So that’s how the code works and you can find the complete source code at the bottom of the article.
Building the deviceUsing Solidworks I made the design and here’s how it looks.
You can download this model so you can take the measurements here:
For this project I choose to use Aluminum sheet metal which I cut it to size using a multi tool. Then on the edge of my desk and with the help of some clamps and laths I bent the sheet metal.
As for the speakers, I printed a circular pattern, attached it to place and using a drill I made all of the holes.
After that I cut the sides to the appropriate form and secured them to the previously bent sheet metal using a glue gun.
At the end I painted the sheet metal box and it was ready for the electronics components to be attached. Again, using a glue gun I secured all of the components, connected everything together and secured the back lid of the device using two bolts.
That’s all, feel free to ask any question in the comments section below.
