Increasing the variable when the button is pressed with Exti. When the variable reaches 5, the 500ms timer will turn on, the led will start flashing, when it reaches 10 the timer will turn off. This process will continue in multiples of 5 and 10. I
I am trying to do this but I cannot do it fully.
MY MAİN CODE
Even the slightest help will open my way. thanks
