Multi Toggle

CAN SOMEONE WITH MORE EXPERIENCE THAN ME HELP WITH THE MISTAKE WITH THIS CODE.

THE PROBLEM IS THAT EITHER PINS 2 OR 3 WILL TOGGLE PINS 12 OR 13.

WHAT I WANT IS PNE 2 TOGGLE PIN 12 AND PIN 3 TOGGLE PIN 13

THANKS. GARY

Button

The circuit:

- LED attached from pin 13 to ground through 220 ohm resistor

- pushbutton attached to pin 2 from +5V

- 10K resistor attached to pin 2 from ground

- Note: on most Arduinos there is already an LED on the board

attached to pin 13.

// constants won't change. They're used here to set pin numbers:

const int buttonPin2 = 2; // the number of the pushbutton pin

const int ledPin13 = 13; // the number of the LED pin

const int buttonPin3 = 3; // the number of the pushbutton pin

const int ledPin12 = 12; // the number of the LED pin

// variables will change:

int buttonState2 = 0; // variable for reading the pushbutton status

int buttonState3 = 0; // variable for reading the pushbutton status

void setup() {

// initialize the LED pin as an output:

pinMode(ledPin13, OUTPUT);

// initialize the pushbutton pin as an input:

pinMode(buttonPin2, INPUT);

// initialize the LED pin as an output:

pinMode(ledPin12, OUTPUT);

// initialize the pushbutton pin as an input:

pinMode(buttonPin3, INPUT);

}

void loop() {

// read the state of the pushbutton value:

buttonState2 = digitalRead(buttonPin2);

// check if the pushbutton is pressed. If it is, the buttonState is HIGH:

if (buttonState2 == HIGH) {

digitalWrite(13, !digitalRead(13)); // toggle state

delay(500); // wait around for 1 sec (1000 ms)

}

// read the state of the pushbutton value:

buttonState3 = digitalRead(buttonPin3);

// check if the pushbutton is pressed. If it is, the buttonState is HIGH:

if (buttonState3 == HIGH) {

digitalWrite(12, !digitalRead(12)); // toggle state

delay(500); // wait around for 1 sec (1000 ms)

}else {

}
