Controladora patrones led con guardado

International Español Software
1

He hecho un codigo en el que con un botón puedo ir cambiando entre x patrones de parpadeo de unos leds, pero cuando se reinicia la placa, la variable que se encarga de ir cambiando de patrón a medida que se va pulsando el botón, se reinicia a 1(que se corresponde con el primer patron).
Mi duda es, ¿como puedo hacer que se almacene la ultima posicion de la variable para que de esta manera aunque reincie la placa, inicie el ultimo patrón que seleccione anteriormente?

int t = 1;
void setup()
{
  
  pinMode (1 , OUTPUT);
  pinMode (2 , OUTPUT);
  pinMode (3 , OUTPUT);
  pinMode (4 , OUTPUT);
  pinMode (5 , OUTPUT);
  pinMode (6 , OUTPUT);
  pinMode (7 , OUTPUT);
  pinMode (8 , OUTPUT);
  pinMode (9 , OUTPUT);
  pinMode (10 , OUTPUT);
  pinMode (11, OUTPUT);
  pinMode (12 , OUTPUT);
  pinMode(13, INPUT);
}

void loop()
{
  if (digitalRead(13)==HIGH){
    t++;
    delay(50);}
    
if (t==1){
  pattern1();}
if (t==2){
  pattern2();}
if (t==3){
  pattern3();}
if (t==4){
  pattern4();}
if (t==5){
  pattern5();}
if (t==6){
  pattern6();}


}

Muy buena explicación y qué quieres que hagamos nosotros si no vemos el código?
Te recomiendo que hagas lo que te pondré a continuación

Moderador.
Lee las Normas del foro y postea el código usando etiquetas.

Respalda el valor de la variable en la eeprom y al iniciar la recuperas.
Googlea "eeprom arduino" que vas a encontrar mucha información al respecto.

4

Usted perdone, ahí está el código.

Muchas gracias!!
Buscaré mas info.
