Any tips on the code for this? Por favor?
Clearly you've invested NO effort in trying anything, but just to get you to quit whining:
unsigned long lastSwitchOnTime = 0;
void isr1()
{
if(millis() - lastSwithOnTime > 5) // Ignore any events that happen within 5 milliseconds of the last one
{
buttonPushCounterOn+=1;
if(buttonPushCounterOn > 60)buttonPushCounterOn =0; // rollover after 60.
}
lastSwitchOnTime = millis();
}
