How do you want to have
your wipers become more intelligent? In this way, they could remember
how frequent you need to use them. But of course, this will need the
help of an ATmega8L microcontroller.
When you need to activate the wiper, you just press the button and
it will run in one course. There is a 45 seconds waiting time that if
you do not press the button, it will go on standby while telling itself
that only one course is needed. The system will activate the wiper again
if the button is pressed before 45 seconds. The good thing is that it
will remember the interval when you pressed the button.
