 The active speaker simply needs to be toggled on or off to work.
-"digitalWrite (GPIO_PIN, STATE)" -- where:
+<code>
-     GPIO_PIN = the wiringPi pin number or the name you declared for that pin
+digitalWrite (GPIO_PIN, STATE)
-     STATE = HIGH or LOW to either enable or disable the GPIO_PIN
+</code>

 The passive speaker needs to also be given a tone, in Hz, to function.
-"softToneWrite (GPIO_PIN, TONE), where:
+<code>
-     GPIO_PIN = the wiringPi pin number or the name you declared for that pin
+softToneWrite (GPIO_PIN, TONE)
-     TONE = Frequencyof tone to use, or the name you declared for that variable

 ====GPIO MODE SETTING====
 To initialize our GPIO pins, we use the pinMode() function with the first argument being the pin number, and the second argument being the state (input or output).
