Description: It will play a song (Ode to Joy), and there are 7 leds display cording to the rhythm, believe you'll like it.
Here we go:
Code:
[code]
/*
* define a1 to b5 and assign the frequency value
*/
int a1=523; //alto Do
int a2=587; //alto Re
int a3=659; //alto Mi
int a4=698; //alto Fa
int a5=784; //alto So
int a6=880; //alto La
int a7=988; //alto Xi
int b5=392; //bass So
int PWMPin=9;
/*
* we will support you a sheet which contains all of the frequency belong to notes in every tone.
*/
void setup() {
// put your setup code here, to run once:
pinMode(1, OUTPUT);
pinMode(2, OUTPUT);
pinMode(3, OUTPUT);
pinMode(4, OUTPUT);
pinMode(5, OUTPUT);
pinMode(6, OUTPUT);
pinMode(7, OUTPUT);
pinMode(PWMPin, OUTPUT);
}
void loop() {
// put your main code here, to run repeatedly:
/*
* the following code tone(8, a3) means output pin 8, frequcy is a3
* delay(375) means delay the frequcey for 375ms, all of the code you can modifate
* the numbered musical notation of ODe to Joy:
* 3345|5432|1123|3·22-|
* 3345|5432|1123|2·11-|
* 2231|23431|23432|125-|
* 3345|5432|1123|2·11-|
