There is a pretty huge amount of code in this Sketch.
Connect the other side of the 1 k ohm resistor to ground(GND) pin on the Arduino.
All fame goes to, dipto Pratyaksa for making the Sketch code and sharing it with us!
If you have an Arduino Uno(which most people have connect the components with the help of the image below.If you connect without the resistor, the buzzer will be a lot louder, and the sound quality might degrade.Int noteDuration 1000 / tempothisNote; buzz(melodyPin, melodythisNote, noteDuration / to distinguish the notes, set a minimum time between them.the note's duration 30 seems to work well: int pauseBetweenNotes noteDuration *.30; delay(pauseBetweenNotes / stop the tone playing: buzz(melodyPin, 0, noteDuration else intln 'Mario Theme int size sizeof(melody) / sizeof(int for (int thisNote 0; thisNote size; thisNote) / to calculate the note duration.Today I found a complete post on how to play Super Mario Bros theme song on a piezo buzzer!Below is an illustration of how to connect the buzzer and resistor to an Arduino Nano.Connect the positive side of the buzzer to digital pin 3, then the negative side to a 1k ohm resistor.Another idea is using a potentiometer instead of a resistor to act as a volume controller!Its very simple and fun, and great as a beginner Arduino project.
Arduino Mario Bros Tunes With Piezo Buzzer and PWM Connect the positive side of the Buzzer to pin 3, then the negative side to a 1k ohm resistor.
DigitalWrite(targetPin, high / write the buzzer pin high to push out the diaphram delayMicroseconds(delayValue / wait for the calculated delay value digitalWrite(targetPin, LOW / write the buzzer pin low to pull back the diaphram delayMicroseconds(delayValue / wait again or the calculated delay value digitalWrite(13, LOW.
Remember to connect the buzzer the right way, the buzzer has positive and negative pins!
I modified the code posted by Dipto and added the PWM-pitches in directly into the Sketch, so you dont have to mess around with Arduino libraries!
Below is an illustration of how to connect the buzzer and resistor to an Arduino Uno.
