Update:
I changed the code to this, but it does not work either.
`if ((millis() - lastDebounceTime) > debounceDelay) {
if (button) {
//DEBOUNCING
if (!button_prev && button) {
int e = input[j];`
I am trying to debounce a button and integrated this code http://arduino.cc/en/Tutorial/Debounce into my sketch. The result is, that there is no reaction to the button at all. I can't figure out the mistake, but maybe someone else sees what I overlook.
Circuit
Parts marked with //DEBOUNCING are only for the purpose of it, parts marked //DEBOUNCE relevant are necessary for the code to run as well when there is no debouncing.
void setup() {
Serial.begin(9600);
//setting button pin as input and LOW
pinMode(8, INPUT);
digitalWrite(8, LOW); //DEBOUNCE relevant
//setting input pins as output
int act_pin[6] = {A0, A1, A2, A3, A4};
int k = 0;
for (k = 0; k < 5; k++) {
pinMode(act_pin[k], OUTPUT);
}
//setting state pins as output
int z_pin[5] = {2, 3, 4, 5};
int a = 0;
for (a = 0; a < 4; a++) {
pinMode(z_pin[a], OUTPUT);
}
//setting output pins as output
int out_pin[6] = {9, 10, 11};
int b = 0;
for (b = 0; b < 3; b++) {
pinMode(out_pin[b], OUTPUT);
}
//setting input
for(k = 0; k < 5; k++) {
randomSeed(analogRead(5));
int i = random(2);
if(i == 1){
digitalWrite(act_pin[k], HIGH);
input[k] = 1;
Serial.print(input[k]);
}
else{
digitalWrite(act_pin[k], LOW);
input[k] = 0;
Serial.print(input[k]);
}
}
//setting initial situation
digitalWrite(2, LOW);
digitalWrite(3, HIGH);
digitalWrite(4, LOW);
digitalWrite(5, LOW);

//setting initial state

void loop() {

// DEBOUNCING
if (button != button_prev) {
lastDebounceTime = millis();
}
if ((millis() - lastDebounceTime) > debounceDelay) {
if (button != button_prev) {
//DEBOUNCING
if (!button_prev && button) {
int e = input[j];
//provides a nice output
Serial.println(" ");
Serial.print("Current lamp being processed:");
Serial.println(j);
Serial.println(" ");
Serial.print("Current input:");
Serial.println(e);
delta(e, z);
Serial.print("State outside function:");
Serial.println(z);
lamda(e, z);
j = (j+1) % 5;
}
}
}
