Add the following snippet to your HTML:. In this video I explain how you can use an Arduino to make music using just a speaker and a resistor. Like many similar projects, this one generates tones that match the notes of a piano.
Unlike many of these projects, however, this one does not use a lookup table to obtain the frequencies. Instead, the tones are generated using a calculation. The calculation accepts a number from 1 through to This number correlates to a key on an key piano.
The Arduino library offers a tone function which can be used to generate square-wave tones, but this function is unable to generate tones under 31Hz. An key piano has a few notes with frequencies that fall below 31Hz. Instead, I will show you how to generate square-wave tones using a simple delay. This project works at a microsecond level.
A microsecond is one millionth of a second. One last thing about this project is that, despite the issues described above, the code for the project is really rather small, as the code just about fits onto a single screen your resolution may vary!
To be fair, that is without any code comments, but a link to fully commented code is available in the video description. Please log in or sign up to comment. Project in progress by Michael Marinis.

Especially if you are using an Arduino and you have lots of pins free, you can easily add sound effects to your project by just investing in an extra SD card module and a normal speaker.
The Arduino Synthesizer
Thanks to the Arduino community who have developed some libraries to build this in a fast and easy way. We have also used IC LM here for amplification and noise cancelation purpose. For playing sounds from SD Card using Arduinowe need audio files in. To make an arduino mp3 playerthere are a lot of mp3 shields are available which you can use with arduino.
Step 2: Arduino can play a wav file in the following format. You can toy around with the settings later, but these settings were experiment to be the best in quality.
Then feed in the above settings. Once done it should look something like this in the below image. Wav file format. It will also be downloaded once the conversion is done.
Step 5: Finally format your SD card and save your. Make sure you format it before you add this file. Also remember the name of your audio file. Similarly you can select any of your four audios and save them with names 1, 2, 3 and 4 Names should not be changed. I have converted four songs and have saved them as 1. The complete circuit diagram is shown in the Image below. As we know our audio files are saved into the SD card, hence we interface a SD card reader module with our Arduino.
It is further listed in the table below. Now the Arduino will be able to read the music file from the SD card and play it on the pin number 9. But the audio signals produced by the Arduino on pin 9 will not be audible much. The amplifier shown above is designed for a Gain of and the Vdd pin 6 is powered by the 5V pin of the Arduino.
It can withstand a maximum of 15V. Learn more about this gain amplification configuration for LM here. We also have two push buttons connected to the pin 2 and 3 of the Arduino. I have used these buttons just to demonstrate its abilities; you can play the song whenever required. Check the Demo Video at the end.
You can assemble this circuit completely over a Breadboard as shown in the picture below. Once we are ready with the Hardware and the SD card, we are just one step away playing those songs. Insert the card into your SD card module and follow the steps below.
Step 1: As said earlier we will be using a library to make this project work. The link for the library is given below.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. If nothing happens, download GitHub Desktop and try again. If nothing happens, download Xcode and try again. If nothing happens, download the GitHub extension for Visual Studio and try again.How to Play audio with Arduino
Every code here should run on every arduino board without problems. The sketches rely solely on the tone function from Arduino, so the sounds are all monophonic. On the bright side, libraries are not required. If you want to compare the code with the original score, I try to group the notes in a measure as one line of ccode and the staves as groups of lines. However, in some cases notes will be tied together among measures or be dotted and this rule is broken.
Just connect an piezo to the board and you are good to go. Pin 11 is used in every sketch because some piezo speakers can be connected between it and the close GND pin without any wiring. You can use basically any pin, as long as they can be used as digital pins pins A6 and A7 of the Arduino Nano and mini are analog only. Just remember to assign the pin number to the buzzer variable.
There are two kinds of piezo buzzers: active and passive. The active one that plays a specific pitch when powevered and is not good for this purpose. The passive kind functions like a speaker, reproducing the pitch you apply to it. You can test the piezo speaker with the "blink" example, the good piezo speaker will just click, while the other kind will play a pitch every other second.
Every sketch here has been written by myself, although based on scores I found online or books I own. These scores are linked in each file when possible. You can use the sketches for anything, I only kindly ask that you give credit if you use these codes on a tutorial, video, example, etc.The Arduino is able to output sound through a library that has been developed called the Tone Library.
By creating an interface and a program that can call certain values to be output to an audio out, the Arduino Synthesizer is a robust tool for making a rudimentary noise machine. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. The grain consists of two triangular waves of adjustable frequency, and adjustable decay rate. The repetition rate is set by another control. I have attached the code for the Arduino to this Instructable.
You will need a USB 2. After you have uploaded the code from your computer, go ahead and attach the Proto Shield to your Arduino. You have many options when it comes to power.
The Arduino is capable of running on a 9v wall wart power supply, or you may use a 9V battery with a battery clip to a size M coaxial DC power plug. You may also power via your USB cable. The circuit diagram was made with Fritzingit has also been attached to this step.
By using a breadboard to build the circuit first, it is much easier to transfer the circuit to your Protoboard later.
Then, connect the signal wires from the potentiometers to Analog Input on the Arduino. Connecting the potentiometers will control the grain, frequency, and decay of the synthesizer.
Arduino Random Music Generator
You will need a 10K ohm resistor between the arduino board and the positive lead of your audio jack. Connect the negative lead of your jack to ground rail of the breadboard. One lead of your photoresistor is wired directly to your 5V positive rail on the breadboard, as well as Analog Input 5 on the Arduino. The other lead of the photoresistor is connected to a 10K ohm resisted ground rail. The remaining leads are connected to ground, and the 5V positive rail that is resisted by a 10K ohm resistor.
The tactile switch has four leads. Allow the switch to straddle the bridge of the breadboard.Project tutorial by Arnov Sharma.

An Arduino microcontroller board. There are many versions of the Arduino, but I would recommend the Arduino Duemilanove. Three resistors depending on your LEDs, the resistor value will be different - check the ratings on the LEDs to see what resistance corresponds to their maximum brightness, without burning them out 4.
A solderless breadboard 5. A computer 7. Arduino Software Environment 2. Processing Software Environment 3. The "arduino" library for Processing 4. In order to have the Arduino access the LEDs, you have to build a small circuit on a solderless breadboard. The breadboard has two parts: the inner rails which run width-wise and the outer rails which run length-wise. The rails are electrically connected along their lines, so you can connect components without actually soldering them together.
Here is how to make our simple circuit: 1. Run a wire from the digital GND port of the Arduino to the negative outer rail of the breadboard, as shown in image 1. Place your three resistors I used 1kilo-ohm resistors for this example, which matched my LEDs well enough in an evenly-spaced fashion on the inner rails of the breadboard. Note that on a breadboard, a line runs length-wise, halfway down the middle. This separates the left inner rails from the right inner rails, so you can connect more components.
Position the resistors so that they bridge the gap between the inner rails, as shown in image 2. Place the LEDs right next to the right side of the resistors, with the anode the longer end in the slot right next to the resistor, and the cathode the shorter end into the slot that is offset to the resistors by 1 slot, as shown in image 3 see image 4 to see the difference between an anode and a cathode.
Run wires from the cathode rail of the LEDs to the ground outer rail, as shown in image 5. Run wires from the anode side of the resistors to digital pins 12, 8, and 2 on the Arduino to complete the circuit, as shown in image 6 and 7. Now that we have our circuit made, it's on to the programming. Programming the Arduino is pretty simple. Through a couple of small programs, your simple LED circuit will be dancing to the beat in no time.This is my Arduino project.
It is a VU meter, where the LEDs light up to the tune, in a more accurate way to say is the volume of the music. It is comprised of a sound detector board and 10 differently colored LEDs which depicts the meter. I also add Photoresistance to my project to make it even better. There is a blue LED light at the end of this clip which is manipulated by own. This is a kind of sensor that detects whether the light should be turned on or turned off.
Oh, by the way, a VU meter is a volume indicator tool usually represented by either a needle and a gauge or with LEDs. Of course, the latter looks cooler! VU meters are more commonly known for their visual appeal, with LED lights lighting up to the sound of music!
Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. I decided on ordering my LEDs on the same roll to be clear and obvious. I started from left to right, from red to green. I did not count the blue LED because it's for Photoresistance. Using red, yellow, green, and blue LEDs for my project, it seems to be more attractive. I encourage you to design your own pattern that suits your own creative style!
Connect all the cathodes aka negative pins of each of the LEDs to the ground rail on the breadboard. Then, connect this ground rail to the GND pin on the Arduino board.
Arduino LED Music
Connect the free end of each of the resistors starting from the bottommost LED to pins 2 to 11 in consecutive ascending order. Connect the VCC pin on the sound detector board to the 3. Connect the Envelope pin on the sound detector board to the A0 pin on the Arduino board. Photoresistance does not have a positive and negative side. So it doesn't matter which side is connecting to which place. Connect one side of Photoresistance to the anodes. And that is it! This is only a reference for you.
The first image is my sound, and the second image is my Photoresistance sensor. Play some music, the ones with more volume changes would result in a prettier light show. Remember to turn off the lights and watch the music! There are many songs that did very well, have fun! Add Teacher Note. For the Photoresistance: Photoresistance does not have a positive and negative side. Did you make this project? Share it with us! I Made It!
