I am trying to write a simple program that will cycle threw an array using push buttons. My current version of the program uses if statements and print lines. My goal is to have contact information for 4 people stored in an array. I can either have an array of strings per person or make different arrays of strings for the different type of information (ie names, phone numbers). I would like one push button to style threw the data in one direction and another push button to cycle threw the data in the other direction. This is my code so far using the if statements. I modified the code from a traffic light tutorial hence you will see some of the variables named after colors.
//------------------------------- Declare variables
int ledPinOne = 2;
int ledPinTwo = 3;
int ledPinThree = 4;
int ledPinFour = 5;
int buttonPin = 6;
int state = 0;
char user_name_array[32];
char econ_one_name_array[32];
char econ_two_array[32];
char econ_three_name_array[32];
//------------------------------- Setup
void setup() {
Serial.begin(9600);
//------------------------------ Sets pins for I/O
pinMode(ledPinOne, OUTPUT);
pinMode(ledPinTwo, OUTPUT);
pinMode(ledPinThree, OUTPUT);
pinMode(ledPinFour, OUTPUT);
pinMode(buttonPin, INPUT);
Serial.println("ID");
Serial.println(user_name_array);
}
//------------------------------- Main Program
void loop() {
if (digitalRead(buttonPin))
{
if (state == 0)
{
Serial.println("Athlete");
Serial.println("John Smith");
Serial.println("No allergies, no medications");
Serial.println(" ");
setLights(HIGH, LOW, LOW, LOW);
state = 1;
}
else if (state == 1)
{
Serial.println("Emergency Contact - Sister");
Serial.println("Eliza Smith");
Serial.println("Cell - 333.888.777");
Serial.println(" ");
setLights(LOW, HIGH, LOW, LOW);
state= 2;
}
else if (state == 2)
{
Serial.println("Emergency Contact - Hermosita");
Serial.println("Jackie Smith");
Serial.println("Cell - 777.888.7777");
Serial.println(" ");
setLights(LOW, LOW, HIGH, LOW);
state= 3;
}
else if (state == 3)
{
Serial.println("Emergency Contact - Father");
Serial.println("Michael Smith");
Serial.println("Cell - 888.777.777");
Serial.println(" ");
setLights(LOW, LOW, LOW, HIGH);
state = 0;
}
delay(1000);
}
}
void setLights(int red, int yellow, int green, int blue)
{
digitalWrite(ledPinOne, red);
digitalWrite(ledPinTwo, yellow);
digitalWrite(ledPinThree, green);
digitalWrite(ledPinFour, blue);
}
I also have 4 leds setup. When the button is pushed one of the LEDs turn on and then when the button is pushed again it turns it off and turns the second one on and so forth.
thank you in advance for any help.
