got pretty bored so I made this
it compiles fine on my machine so if you have any errors I will fix them
int switchPin = 2; // switch is connected to pin 2
int led1Pin = 8;
int led2pin = 9;
int val; // variable for reading the pin status
int val2; // variable for reading the delayed status
int buttonState; // variable to hold the button state
int Mode = 0; // What mode is the light in?
void setup() {
pinMode(switchPin, INPUT); // Set the switch pin as input
pinMode(led1Pin, OUTPUT);
pinMode(led2pin, OUTPUT);
buttonState = digitalRead(switchPin); // read the initial state
}
void loop(){
val = digitalRead(switchPin); // read input value and store it in val
delay(10); // 10 milliseconds is a good amount of time
val2 = digitalRead(switchPin); // read the input again to check for bounces
if (val == val2) { // make sure we got 2 consistant readings!
if (val != buttonState) { // the button state has changed!
if (val == LOW) { // check if the button is pressed
if (Mode == 0) {
Mode = 1;
} else {
if (Mode == 1) {
Mode = 2;
} else {
if (Mode == 2) {
Mode = 3;
} else {
if (Mode == 3) {
Mode = 0;
}
}
}
}
}
}
buttonState = val; // save the new state in our variable
}
// Now do whatever the lightMode indicates
if (Mode == 0) { // all-off
digitalWrite(led1Pin, LOW);
digitalWrite(led2pin, LOW);
}
if (Mode == 1) {
digitalWrite(led1Pin, HIGH);
digitalWrite(led2pin, LOW);
}
if (Mode == 2) {
digitalWrite(led1Pin, LOW);
digitalWrite(led2pin, HIGH);
}
if (Mode == 3) {
digitalWrite(led1Pin, HIGH);
digitalWrite(led2pin, HIGH);
}
}
Cheers
