Buzzer - Set Frequency

This block sets the Buzzer to produce a sound at the desired frequency (Hz) for the set duration (milliseconds).
If the duration is set to 0, then the Buzzer will continuously be active until a Buzzer - Off block is encountered.

Note: If the duration is set (not 0) this block is holding. Which means the frequency must complete playing before the program goes to the next block in the script.

Issues

The Buzzer trinket utilizes a resource called a timer. This can cause issues with analog write (PWM), the IR Receiver, and other functions. Undesired or unintended behavior can occur when this timer resource is being accessed by different things at the same time.
