-Below is a complete example that produces two different pulse trains with the signal output linked to the ESP32 device's built-in LED.  For illustrative purposes tick duration is set to a very long 100𝛍s and pulse times range from of 1000-10,000 ticks so that the individual pulses are easily discernable on the LED.
