mban21 Guest; Keyboard/Electric piano controlled by arduino.
13 keys, 20x4 LCD display, and 2 buttons to reset or change songs.I'm an Electrical Engineering student and in one of my classes we had a semester long project.
Use 2 interrupts. When a button is pushed, that particular PWM signal is generated through the Piezo Electric Buzzer.Now for the record and repeat mode, play a few tones using different buttons. But after some troubleshooting and some help, I managed to code my for loops and my interrupts correctly. Circuits Making an array for the tones was easy, it was the tempo that was a bit interesting to make.
And download the LCD I2C Arduino Library. I had help from this website Dec 25, 2014, 05:40 pm Last Edit: Dec 25, 2014, 05:47 pm by mban21. As first, I hope my thread is in right place. The only trouble was figuring out the interrupts and the for loop. It is a simple project made using Arduino UNO, few push buttons and a Piezo Buzzer. ***************************************************************************************************************************************************************I coded the songs using arrays and a for loop to step through the arrays.
For example, Flamingo is a 178 bpm. Troubleshooting is the best way to learn sometimes!
its positive terminal to Pin 10 of Arduino. During repeat mode, it stays OFF.An important point to understand here is that I did not use the tone() function of Arduino.
There are 12 keys on the piano, each of which respectively activates one note from C,C#,D,D#,E,F,F#,G,G#,A,A#,B. The project was open-ended and it to incorporate something in the electronics field of study. As you can see from the circuit diagram, it is a fairly simple circuit.The design of Arduino Piano circuit is very easy. We know that Arduino is capable of producing PWM signals.I will be using this feature of Arduino to generate tones.
Using ratios and number manipulation I can get an half note, eighth note, sixteenth note, etc. It is necessary that you connect the Piezo Buzzer to one of the PWM capable pins of Arduino. An electronic keyboard with 7 piano keys, programmed to Middle B/A/G/F/E/D/C, and an 8th button used to access a menu of preset songs on a 16x2 LCD screen. I used a bool to latch on my code, and to latch out when I needed to with the interrupts.
Doing a project by yourself is challenging but very rewarding.
I decided to make a piano using Arduino since I had knowledge from the previous year of coding. 13 keys, 20x4 LCD display, and 2 buttons to reset or change songs.Arduino Piano using an Arduino Mega2560. The design of Arduino Piano circuit is very easy. These pins act as the tone input pins.
I noticed that sometimes changing songs, there is sometimes issues changing songs. I think maybe it's due to the interruption of the for loop and the Arduino has trouble changing into the next song. As soon as the Arduino enters Interrupt Mode, all the previously pressed tones are played back through the Piezo Buzzer.During normal tone playback i.e. Code my piano keys with while loops. Makes the circuit naturally ON or HIGH. Display.

First, connect a 5V Piezo Buzzer i.e. The project display is on Youtube. Dependent on whether you use an active or passive buzzer, there will be differences in sound quality, etc.Make sure to make a header file/include a Pitches.h file.
Once the power to the circuit is turned on, Arduino is ready to accept the input from the buttons.Each button is associated with a PWM signal in the code. There are two ways to do the tempo array, here's one way to do the ratio, since all tempo is a ratio based on BPM and 60, 000 ms (1 minute in milliseconds). 337 / 2 = 168.5 == 169 ms. The other way to generate tones using Arduino is to use the function tone () function.Using tone () function, you can generate square waves of different frequencies but with fixed duty cycle (50%). I decided to make a piano using Arduino since I had knowledge from the previous year of coding.
You can try to generate sounds of different frequencies using that function.A fun DIY Project called Arduino based Piano is implemented here.
A piano is a musical instrument that produces different types of sounds when we press different buttons. ***Feel free to change components or pins as needed, this is just what I did for my project. Arduino Piano using an Arduino Mega2560. Collaborator.
So plug in the 5V, ground, SDA, SCL from LCD to Arduino.
