How can I combine your experiments?

[Jacket_Chen]

I bought your ARDX starter kit for Arduino hoping it would help my daughter’s science fair project. How can I combine your experiments? She wants to remotely control (RF) LEDs and a noisemaker (piezo I guess), but if the wireless control is too hard to do, wants a push button. So basically I want to combine CIRC-02 + CIRC-06 with a pushbutton. (We only need 5 LEDs not 8; CIRC-07 has two pushbuttons, can’t it be just done with one?) We have tried combining the projects and code ourselves and nothing has worked. Can do the individual projects, just not the combination. HOW CAN WE COMBINE THEM?

Maybe you can have the following demo tested. However, i don’t try it yet ~~

[code]int speakerPin = 9;
const int buttonPin = 2;
int ledPins[] = {4,5,6,7,8};

int length = 15; // the number of notes
char notes[] = "ccggaagffeeddc "; // a space represents a rest
int beats[] = { 1, 1, 1, 1, 1, 1, 2, 1, 1, 1, 1, 1, 1, 2, 4 };
int tempo = 300;

int buttonState = 0;

void setup() {
pinMode(speakerPin, OUTPUT);
pinMode(buttonPin, INPUT);

for(int i = 0; i < 5; i++){ //this is a loop and will repeat eight times
pinMode(ledPins[i],OUTPUT); //we use this to set each LED pin to output
}
}

void loop() {

while(buttonState == HIGH) {
oneAfterAnotherNoLoop();
for (int i = 0; i < length; i++) {
if (notes[i] == ’ ') {
delay(beats[i] * tempo); // rest
} else {
playNote(notes[i], beats[i] * tempo);
}

// pause between notes
delay(tempo / 2); 

}
}
if(buttonState == LOW)
{digitalWrite(speakerPin, LOW);}
}

void oneAfterAnotherNoLoop(){
int delayTime = 100; //the time (in milliseconds) to pause between LEDs
//make smaller for quicker switching and larger for slower
digitalWrite(ledPins[0], HIGH); //Turns on LED #0 (connected to pin 2 )
delay(delayTime); //waits delayTime milliseconds
digitalWrite(ledPins[1], HIGH); //Turns on LED #1 (connected to pin 3 )

//Turns Each LED Off
digitalWrite(ledPins[7], LOW); //Turns on LED #0 (connected to pin 2 )

digitalWrite(ledPins[0], LOW); //Turns on LED #7 (connected to pin 9 )
delay(delayTime); //waits delayTime milliseconds
}

void playTone(int tone, int duration) {
for (long i = 0; i < duration * 1000L; i += tone * 2) {
digitalWrite(speakerPin, HIGH);
delayMicroseconds(tone);
digitalWrite(speakerPin, LOW);
delayMicroseconds(tone);
}
}

void playNote(char note, int duration) {
char names[] = { ‘c’, ‘d’, ‘e’, ‘f’, ‘g’, ‘a’, ‘b’, ‘C’ };
int tones[] = { 1915, 1700, 1519, 1432, 1275, 1136, 1014, 956 };

// play the tone corresponding to the note name
for (int i = 0; i < 8; i++) {
if (names[i] == note) {
playTone(tones[i], duration);
}
}
