    <p>I am trying to make my Arduino blink "SOS" in Morse Code as my first real programming project ever.</p> <p>I have succeeded in doing so, however now I would like to more efficiently write the code. Here is the my version. How can a while loop be implemented to get the S blinking twice? That seems to complicate keeping track of iterations with a counter.</p> <pre><code>int led = 13; //yj Integer representing dit (morse ' . ') int dit = 500; //yj Integer representing dah (morse ' - '&gt;) //yj Testing a multiple of another constant integer to make the timing scalable. int dah = dit*3; int blankTime = 100; // the setup routine runs once when you press reset: void setup() { // initialize the digital pin as an output. pinMode(led, OUTPUT); } // the loop routine runs over and over again forever: void loop() { digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) delay(dit); // wait digitalWrite(led, LOW); // turn the LED off by making the voltage LOW delay(blankTime); // wait digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) delay(dit); // wait digitalWrite(led, LOW); // turn the LED off by making the voltage LOW delay(blankTime); // wait digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) delay(dit); // wait digitalWrite(led, LOW); // turn the LED off by making the voltage LOW delay(blankTime); // wait digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) delay(dah); // wait digitalWrite(led, LOW); // turn the LED off by making the voltage LOW delay(blankTime); // wait digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) delay(dah); // wait digitalWrite(led, LOW); // turn the LED off by making the voltage LOW delay(blankTime); // wait digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) delay(dah); // wait digitalWrite(led, LOW); // turn the LED off by making the voltage LOW delay(blankTime); // wait digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) delay(dit); // wait digitalWrite(led, LOW); // turn the LED off by making the voltage LOW delay(blankTime); // wait digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) delay(dit); // wait digitalWrite(led, LOW); // turn the LED off by making the voltage LOW delay(blankTime); // wait digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) delay(dit); // wait digitalWrite(led, LOW); // turn the LED off by making the voltage LOW delay(blankTime); // wait } //TODO: //Loop counter implementation for multiples (SOS = 3 dit, 3 dah, 3 dit.) </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
