/*Play a Morse Code message on the speaker Rules of Morse Code: - Dots are 1 'unit' of sound - Dashes are 3 'units' of sound (3 times as long as a dot) - Spaces between symbols within the same letter are 1 'unit' of silence - Spaces between letters are 3 'units' of silence - Spaces between words are 7 'units' of silence */ void setup(){ pinMode(10,OUTPUT); //Set the speaker as an 'OUTPUT' } void loop(){ //S //dot tone(10,500); //play a tone of 500 hertz on the speaker delay(300); //wait one 'dot' with the speaker on noTone(10); //turn off the sound delay(300); //wait before the next symbol in a letter //dot tone(10,500); //play a tone of 500 hertz on the speaker delay(300); //wait one 'dot' with speaker on noTone(10); //turn off the sound delay(300); //wait before the next symbol in a letter //dot tone(10,500); //play a tone of 500 hertz on the speaker delay(300); //wait one 'dot' with speaker on noTone(10); //turn off the sound delay(900); //wait before the next letter in a word //O //dash tone(10,500); //play a tone of 500 hertz delay(900); //wait one 'dash' with speaker on noTone(10); //turn off the sound delay(300); //wait before the next symbol in a letter //dash tone(10,500); //play a tone of 500 hertz delay(900); //wait one 'dash' with the speaker on noTone(10); //turn off the sound delay(300); //wait before the next symbol in a letter //dash tone(10,500); //play a tone of 500 hertz delay(900); //wait one 'dash' with speaker on noTone(10); //turn off the sound delay(900); //wait before the letter in a word //S //dot tone(10,500); //play a tone of 500 hertz on the speaker delay(300); //wait one 'dot' with the speaker on noTone(10); //turn off the sound delay(300); //wait before the next symbol in a letter //dot tone(10,500); //play a tone of 500 hertz on the speaker delay(300); //wait one 'dot' with the speaker on noTone(10); //turn off the sound delay(300); //wait before the next symbol in a letter //dot tone(10,500); //play a tone of 500 hertz on the speaker delay(300); //wait one 'dot' with the speaker on //noTone(10); //turn off the sound delay(2100); //wait before the next word } // (c) 2018 Let's Start Coding.
