To further specialize your microcontroller, we carry a large selection of daughter boards (shields) which can add powerful sensors, GPS, or even LCD screens to your project! Just getting started with microcontrollers? We carry a variety of Arduino starter kits to get you reading sensors and blinking lights as easily as quickly as possible! We carry a variety of Arduino compatible microcontrollers from several manufacturers, each with their own specific strengths and purposes. Their ability to interact with the real world by way of sensors and other electronics makes them ideal for automation such as watering a plant when it is dry, reading the weather, or controlling lights when it gets dark – the possibilities are endless. These easy to program devices can read sensors, control relays, light up LEDs, and even talk to one another. Arduino Arduino is the most popular open source microcontroller platform on the market.
#MP3 PLAYER ARDUINO SERIAL#
here we set the pin mode of the pushbuttons, turn on the Arduino internal pull up resistors, initialize the serial communication among other things. Next, we move to the void setup function. SoftwareSerial mySerial ( 10, 11 ) # define Start_Byte 0x7E # define Version_Byte 0xFF # define Command_Length 0x06 # define End_Byte 0圎F # define Acknowledge 0x00 //Returns info with command 0x41 # define ACTIVATED LOW int buttonNext = 2 int buttonPause = 3 int buttonPrevious = 4 Then we declare the pins on the Arduino to which our pushbuttons and Dfplayer mini are connected.
#MP3 PLAYER ARDUINO SOFTWARE#
The first thing we do in the code is, as usual, include the libraries needed for the project in this case, the software serial library. Additional functions can be found in the description of the video on youtube.
Although the DFplayer mini has its own library that enables us to write the code easily, it is not used for this tutorial, Instead, we created functions which can be called to perform the tasks involved with this project. The code for this project is a fairly simple one, we will be using the Arduino software serial library which comes pre-installed on the Arduino IDE as the communication between the Arduino and the DFplayer mini is over serial as earlier stated and to avoid code uploading issues that may arise from using the hardware serial(pin D0 and D1), we will be using a software serial connection. Go over the schematics once again to ensure everything is as it should be before proceeding to the code.
#MP3 PLAYER ARDUINO HOW TO#
You probably noticed that the pushbuttons were connected without a pull-up or pull-down resistor, check this () tutorial to know how to use the pushbuttons without pull up or pull down resistors on the Arduino. Thank you for your support!Ĭonnect the components as shown in the image below.Īs shown above, the connection between the Arduino and the DFplayer mini is pretty simple. The pin connections are described below to make it easier to follow.Ī speaker is connected to the speaker output(pin 6 and 8) of the DF player mini to air the sound being played. I get a small percentage of each sale they generate. The following parts are needed to build this project and each part can be bought by clicking on the link in front of it.įull disclosure: All of the links above are affiliate links. Ready? let’s build! Required Parts and Where to Buy The music files to be played using the DFplayer mini are pre-stored on an SD card which is inserted into the DF player mini.įor this tutorial, we will be using the Arduino Uno, but you can use any other Arduino or microcontroller to build this project. For this tutorial, we will be building a simple mp3 player which will have 3 buttons, The first button will be used to Play/Pause the music currently being played, while the second one will be used to load the next song(the next button) and the last one will be used to load the previous song ( the previous button).
