This is based on Catduino ( the same function as Arduino )
Descripe: it will play a song ( Ode to Joy ), the single LED will light and off cording to the tone.
Here we go:
[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 n1=36; int n2=72; int n3=108; int n4=144; int n5=180; int n6=216; int n7=252;
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(8, OUTPUT); //pin 8 was set as output pin
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-|
