Arduino. count the number of button press then play sequence

Question

help me to code this program

1. when i press the button once, sequence s1() play.
2. when i press the button twice, sequence s2() play.
3. when i press the button thrice, sequence s3() play.
4. when i press the button 4 times, sequence s4() play.

//code
const int buttonPin = 10; 
int buttonState = 0;
void setup(){
 Serial.begin(9600);
 //initialize pin 2 - 9 as output
 for(int i=2;i<=9;i++){ 
 pinMode(i,OUTPUT);
 }
 pinMode(buttonPin, INPUT);
}
void loop(){
 buttonState = digitalRead(buttonPin);
 if (buttonState == HIGH) { 
 s1();
 s2();
 s3();
 s4(); 
 } 
}
void s1(){
 int i = 2 ;
 for(int z=0;z<=1;z++){
 for(int x=i;x<=9;x++){ 
 digitalWrite(i,HIGH);
 digitalWrite(x-1,LOW);
 delay(500);
 i = i + 1;
 }
 i = 2;
 if(i = 2){
 digitalWrite(9,LOW);
 }
 }
}
void s2(){
 int y = 9; 
 for(int i=0;i<=1;i++){
 for(int x=2;x<=5;x++){
 if(y>=1){
 digitalWrite(x,HIGH);
 digitalWrite(y,HIGH);
 delay(500);
 y = y - 1;
 }
 }
 off();
 y = 9;
 delay(500);
 } 
}
void s3(){
 for(int i=0;i<=2;i++){
 for(int z=2; z<=9;z++){
 if(z % 2 == 0){
 digitalWrite(z,HIGH);
 }
 }
 delay(500);
 for(int z=2; z<=9;z++){
 if(z % 2 == 0){
 digitalWrite(z,LOW);
 }
 }
 delay(500);
 for(int z=2; z<=9;z++){
 if(z % 2 != 0){
 digitalWrite(z,HIGH);
 }
 }
 delay(500);
 for(int z=2; z<=9;z++){
 if(z % 2 != 0){
 digitalWrite(z,LOW);
 }
 }
 delay(500);
 }
}
void s4(){
 for(int i=0;i<=2;i++){
 for(int x=2;x<=9;x++){
 digitalWrite(x,HIGH);
 delay(500);
 }
 off();
 delay(500);
 }
 }
void off(){
 for(int i=2;i<=9;i++){ 
 digitalWrite(i,LOW);
 } 
}

Answer 1

You mean something like that? I've used internal pull-up and button as active-low switch so I've used comparing with LOW:

const int btn = 4;
byte btn_tim_on = 0;
byte btn_tim_off = 0;
byte btn_val = 0;
void setup() {
 pinMode(btn, INPUT_PULLUP);
 Serial.begin(57600); // debug purposes
}
void loop() {
 if (digitalRead(btn) == LOW) {
 if (++btn_tim_on == 5) { // 5 checks before it's considered as key press and every 256*4ms repeat
 ++btn_val;
 }
 btn_tim_off = 80; // about 0.32 second to confirm
 } else {
 btn_tim_on = 0; // reset button pressed timer
 if (btn_tim_off > 0) {
 if (--btn_tim_off == 1) { // call action
 Serial.println(btn_val); // print in serial monitor
 switch (btn_val) {
 case 1: s1(); break;
 case 2: s2(); break;
 case 3: s3(); break;
 case 4: s4(); break;
 default: Serial.println(F("no action")); break;
 }
 }
 } else {
 btn_val = 0; // reset button press counter
 }
 }
 delay(4);
}
// where to place s1, s2, s3 and s4 ...
// playing these actions is blocking, so no keys are detected during "play"

• eleos: Thanks! is there a way to break the loop when i press the button when the loop is running?
