Itty Bitty Buggy: Buzzer Tutorial (mDesigner)

Buzzer

Buggy Base contains a Buzzer capable of producing sounds. When pulses of electricity are sent to the Buzzer, the pulses causes the Buzzer to vibrate and produce an audible sound. Pulses of different frequencies will cause the Buzzer to produce different notes. The following blocks will allow the user to control the Buzzer.

Block: Play Note

Buzzer can be controlled to play a note with the Buzzer - Play Note block.

Function: This block controls the Buzzer to play the selected note for the specified duration. Note: If the duration (seconds) is set (not 0) this block is holding. Which means the note must complete playing before the program goes to the next block in the script. Note: As of mDesigner v1.6: In "online mode" this block accepts whole and decimal numbers. In "offline mode" this block only accepts WHOLE numbers. Decimal numbers will be rounded down. Note - select note to play. Duration - time in seconds to play the selected note.

Example

Description: When activated, this program repeatedly calls the Buzzer - Play Song block in order to play notes using the Repeat block. The amount of time allocated to play the song is calculated by the 0.02 second wait times the number of repeats 400. 0.02 second * 400 = 8 seconds. The Buzzer - Off block MUST be called in order to stop the Buzzer.

Block: Off

This block turns off the Buzzer. It is only useful to use in certain situations such as demonstrated in #Example 3b: Play a song with Buzzer (Offline Mode).

Note: As of mDesigner v1.6, this block has no intended purpose because the Buzzer - Play Note and Buzzer - Play Song blocks will stop automatically based on the duration. It is only useful in certain situations such as demonstrated in #Example 3b: Play a song with Buzzer (Offline Mode). Function: This block controls the Buzzer to stop producing sound.
