	~~==Installing~~ the ~~Arduinomorse Library==~~		This page covers the use of a morse code library to operate a blinking LED on the Arduino Micro.

	~~On to the next part of the project: getting Arduino to run~~ Morse Code~~! See~~ the ~~[[Arduinomorse Library]] page.~~		=Morse Code on the Arduino=

	~~==An Arduinomorse Sketch==~~		First, let's talk about how to get some morse code libraries on the Arduino.

	~~Now we can rewrite our sketch to use the arduinomorse library. NOTE THAT IT MUST BE LOWERCASE:~~		[[Morse Code Arduino]]

	~~<source lang="c">~~		We basically have two options:
	~~#define PIN_STATUS 12~~		* Use the [[Arduinomorse Library]]
	~~#include <morse.h>~~		* Use the [[Morse Library]]
	~~LEDMorseSender sender(PIN_STATUS);~~
	~~//SpeakerMorseSender sender(PIN_STATUS);~~

	~~void setup() {~~
	~~sender.setup();~~
	~~sender.setWPM(20);~~
	~~sender.setMessage(String("v v v de kc7dbu ar"));~~
	~~sender.startSending();~~
	}
	~~void loop() {~~
	~~sender.continueSending();~~
	}

	~~</source>~~

	~~How does this bad boy work? Well,~~ the ~~morse library contains encodings of letters into dots and dashes. These dots and dashes are then encoded into voltage signals that are dits or dashes. When the voltage is applied, the LED lights up.~~

	~~=Blink Speaker=~~

	~~The next part~~ of the ~~project~~ is ~~to connect~~ a ~~speaker in lieu~~ of ~~an LED~~, so that ~~we can use that same voltage to generate morse code tones from a speaker~~.		I'll show an example of using both, so you can get an idea of the advantages/disadvantages of different libraries. Morse code is a good example of how a relatively simple task can quickly become befuddling to implement, but how there are many tasks that already have libraries.

	The ~~speaker I used was a 3 - 28 V DC piezoelectric speaker. No resistors were needed, since I was using 5 volts, which was in the range of the speaker.~~		==The Arduinomorse Library==

	~~==The Circuit==~~		To use the Arudinomorse library, see the [[Arduinomorse Library]] and [[Arduino Installing Libraries]] for installation instructions for getting libraries into the Arduino Development Environment.

	==~~=Breadboard Diagram=~~==		==The Morse Library==

	~~Here is a breadboard layout using Fritzing:~~		To use the Morse library, see the [[Morse Library]] page for installation.

	~~[[Image:bb_BlinkSpeaker.png\|500px]]~~

	As mentioned, pretty straightforward: we're powering the positive and negative buses with the red and black cables, connected to the Arduino's 12 pin and ground, respectively. We then route power from the positive bus to the piezo speaker's red wire, then the voltage passes through the speaker (generating sound), and the remaining voltage passes through the black wire to ground.

	~~Finally,~~ we can use the ~~Arduinomorse~~ library ~~to generate our morse code tones, by switching from a <code>LEDMorseSender</code> object to a <code>SpeakerMorseSender</code> object~~:		Now we can rewrite our sketch to use the arduinomorse library.

	//LEDMorseSender sender(PIN_STATUS);		LEDMorseSender sender(PIN_STATUS);
	SpeakerMorseSender sender(PIN_STATUS);		//SpeakerMorseSender sender(PIN_STATUS);

			The morse library works differently, by giving the user finer-grained control at the character-by-character level, but it follows the same basic idea.

			<source lang="c">
			Morse morse();
			morse.send(s);
			morse.send(o);
			morse.send(s);

On to the next part of the project: getting Arduino to run Morse Code! See the [[Arduinomorse Library]] page.

==An Arduinomorse Sketch==

Now we can rewrite our sketch to use the arduinomorse library. NOTE THAT IT MUST BE LOWERCASE:

<source lang="c">
#define PIN_STATUS 12
#include <morse.h>
LEDMorseSender sender(PIN_STATUS);
//SpeakerMorseSender sender(PIN_STATUS);

void setup() {
sender.setup();
sender.setWPM(20);
sender.setMessage(String("v v v de kc7dbu ar"));
sender.startSending();
}
void loop() {
sender.continueSending();
}

</source>

How does this bad boy work? Well, the morse library contains encodings of letters into dots and dashes. These dots and dashes are then encoded into voltage signals that are dits or dashes. When the voltage is applied, the LED lights up.

=Blink Speaker=

The next part of the project is to connect a speaker in lieu of an LED, so that we can use that same voltage to generate morse code tones from a speaker.

The speaker I used was a 3 - 28 V DC piezoelectric speaker. No resistors were needed, since I was using 5 volts, which was in the range of the speaker.

==The Circuit==

===Breadboard Diagram===

Here is a breadboard layout using Fritzing:

We then route power from the positive bus to the piezo speaker's red wire, then the voltage passes through the speaker (generating sound), and the remaining voltage passes through the black wire to ground.

==Arduinomorse Speaker Sketch Code==

Finally, we can use the Arduinomorse library to generate our morse code tones, by switching from a <code>LEDMorseSender</code> object to a <code>SpeakerMorseSender</code> object:

<source lang="c">
#define PIN_STATUS 12
#include <morse.h>
//LEDMorseSender sender(PIN_STATUS);
SpeakerMorseSender sender(PIN_STATUS);

void setup() {
sender.setup();
sender.setWPM(20);
sender.setMessage(String("v v v de kc7dbu ar"));
sender.startSending();
}
void loop() {
sender.continueSending();
}

</source>

==Upload and Go==

Once you upload the sketch, your piezo speaker should start sending out morse code.
