Try this
const int boton1 = 2;
const int bomba1 = 10;
void setup()
{
pinMode(bomba1, OUTPUT);
}
void loop()
{
if (digitalRead(boton1) == HIGH)
{
// Enciende la bomba 1 durante 3 segundos
digitalWrite(bomba1, HIGH);
delay(3000); // Modifica el tiempo aqui, en milisegundos
digitalWrite(bomba1, LOW);
}
}
After it works , add more things one by one(or take care of the delays)
