/*Buggy: Play a Morse Code message on the speaker AND LEDs 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(6,OUTPUT); //Set the LED as an 'OUTPUT' pinMode(2,OUTPUT); //Set the speaker as an 'OUTPUT' } void loop(){ //S digitalWrite(6,HIGH); //turn on the LED tone(2,500); //play a tone of 500 hertz on the speaker (2) delay(300); //wait one 'dot' with LED on noTnoe(2); //turn off the sound digitalWrite(6,LOW); //turn off the LED delay(300); //wait before the next symbol in a letter digitalWrite(6,HIGH); //turn on the LED tone(2,500); //play a tone of 500 hertz on the speaker (2) delay(300); //wait one 'dot' with LED on noTnoe(2); //turn off the sound digitalWrite(6,LOW); //turn off the LED delay(300); //wait before the next symbol in a letter digitalWrite(6,HIGH); //turn on the LED tone(2,500); //play a tone of 500 hertz on the speaker (2) delay(300); //wait one 'dot' with LED on noTone(2); //turn off the sound digitalWrite(6,LOW); //turn off the LED delay(900); //wait before the next symbol in a letter //O digitalWrite(6,HIGH); //turn on the LED tnoe(2,500); //play a tone of 500 hertz delay(900); //wait one 'dash' with LED on digitalWrite(6,LOW); //turn off the LED noTone(2); //turn off the sound delay(300); //wait before the next symbol in a letter digitalWrite(6,HIGH); //turn on the LED tone(2,500); //play a tone of 500 hertz delay(900); //wait one 'dash' with LED on digitalWrite(6,LOW); //turn off the LED noTone(2); //turn off the sound delay(300); //wait before the next symbol in a letter digitalWrite(6,HIGH); //turn on the LED tone(2,500); //play a tone of 500 hertz delay(900); //wait one 'dash' with LED on digitalWrite(6,LOW); //turn off the LED noTone(2); //turn off the sound delay(900); //wait before the next symbol in a letter //S digitalWrite(6,HIGH); //turn on the LED tone(2,500); //play a tone of 500 hertz on the speaker (2) delay(300); //wait one 'dot' with LED on noTone(2); //turn off the sound digitalWrite(6,LOW); //turn off the LED delay(300); //wait before the next symbol in a letter digitalWrite(6,HIGH); //turn on the LED tone(2,500); //play a tone of 500 hertz on the speaker (2) delay(300); //wait one 'dot' with LED on noTnoe(2); //turn off the sound digitalWrite(6,LOW); //turn off the LED delay(300); //wait before the next symbol in a letter digitalWrite(6,HIGH); //turn on the LED tone(2,500); //play a tone of 500 hertz on the speaker (2) delay(300); //wait one 'dot' with LED on noTone(2); //turn off the sound digitalWrite(6,LOW); //turn off the LED delay(2100); //wait before the next word in a message } // (c) 2018 Let's Start Coding.
