Basically I'm using C to control an external board. (interfacing)
So, what I need the LEDs on the board is to blink until a user inputs char 'a'.
The thing is, if I used scanf, the blinking would pause and wait until the user inputs char 'a'.
Is there any way to avoid pausing the program, but at the same time end the blink loop when the user inputs char 'a'??
Its not necessary to use scanf here.. Any solution will do.
