Please, someone help me out? I'd really appreciate it.
Stary by looking at the BlinkWithoutDelay example. It will show you how to do a symmetrical very slow "tap" to one pin.
Change from millis() timing to micros() and you can have faster "taps".
Change the period at each change of output state and you can have a faster asymmetrical "tap".
Repeat the code in loop() using different parameters and variable and you can have 2 fast, asymmetrical "taps"
