How to create an dynamic heartbeat?

Hi guys, I’m new to Unity and I’m exercising myself trying to make a sort of beat monitor: each time the user presses the spacebar, a blip goes up. Do you know how can I make something like this?

Not exactly sure what you mean by a blip goes up, but heres how to do it…

void Update () {
		if (Input.GetKey (KeyCode.Space)) {
			//blip goes up
		}
}
