A Word on Pins

	You should note that the Morse library uses Pulse Width Modulation (PWM) to activate the speaker. Not all of the Arduino pins are able to do PWM, but the ones that are, are usually indicated as such. On the Arduino Micro, the PWM pins are 3, 5, 6, 9, 10, 11 and 13. On the Arduino Leonardo, the PWM pins are the same.		You should note that the Morse library uses Pulse Width Modulation (PWM) to activate the speaker.

On the Arduino Leonardo, the PWM pins are the same.

			PWM just means that we can send a variable-voltage signal out. Without PWM, all we have is ON and OFF, 1 and 0. But with PWM, we can use variable voltage to control the precise angle of a servo motor, or send a particular sound wave to a speaker.

			Here is the equivalent sketch using the Morse library. Note that this library DOES use pulse width modulation (PWM) to send morse code through the speaker, so we need to switch to pin 9 on the Micro, which supports PWM.

Note that this uses pin 12, which is not a PWM pin. The Arudinomorse library does not use PWM to send morse code to the speaker, so we're good.
