    Need build a circuit that flashes 4x

    Guys, I need some help. I need to build a circuit, that flashes a LED 4 times (only 4x, in a short time, like less than 1/2 second), every time that i click a bottom (click switch). If you can draw me a circuit that may work, I'll be grateful (cuz I'm still learning circuits).
