# Rocket Morse Code Part Four Bug Hunt! Test your Troubleshooting.

You may have already run into some errors in modifying or writing your own code. Don't worry, studies have shown that almost half of all code 'compiles' result in an error!

Donâ€™t be scared by the number of errors that show up when you try to upload this program. There is a single, simple solution!

/*Buggy: Use variables for Morse Code messages. This will make it much easier to update the speed of messages Rules of Morse Code: - Dots are 1 'unit' - Dashes are 3 'units' (3 times as long as a dot) - Spaces between symbols within the same letter are 1 'unit' of no signal - Spaces between letters are 3 'units' of no signal - Spaces between words are 7 'units' of no signal */ //all the variables used in this program are 'integers', shortened to int, which means they are whole numbers. int dit = 200; //milliseconds that a dot will last int dash = dot*3; //milliseconds that a dash will last int symbolSpace = dot; // space between symbols are the same duration as a dot int letterSpace = symbolSpace*3; //space between letters are 3 times the duration of symbol spaces int wordSpace = symbolSpace*7; //space between words are 7 times the duration of symbol spaces int LED = 6; void setup(){ pinMode(LED,OUTPUT); //Set the LED as an 'OUTPUT' } void loop(){ //S digitalWrite(LED,HIGH); //Turn on LED delay(dot); //wait one 'dot' with LED on digitalWrite(LED,LOW); //Turn off LED delay(symbolSpace); //wait before the next symbol in a letter digitalWrite(LED,HIGH); //Turn on LED delay(dot); //wait one 'dot' with LED on digitalWrite(LED,LOW); //Turn off LED delay(symbolSpace); //wait before the next symbol in a letter digitalWrite(LED,HIGH); //Turn on LED delay(dot); //wait one 'dot' with LED on digitalWrite(LED,LOW); //Turn off LED delay(letterSpace); //wait before the next symbol in a letter //O digitalWrite(LED,HIGH); //Turn on LED delay(dash); //wait one 'dash' with LED on digitalWrite(LED,LOW); //Turn off LED delay(symbolSpace); //wait before the next symbol in a letter digitalWrite(LED,HIGH); //Turn on LED delay(dash); //wait one 'dash' with LED on digitalWrite(LED,LOW); //Turn off LED delay(symbolSpace); //wait before the next symbol in a letter digitalWrite(LED,HIGH); //Turn on LED delay(dash); //wait one 'dash' with LED on digitalWrite(LED,LOW); //Turn off LED delay(letterSpace); //wait before the next letter in a word //S digitalWrite(LED,HIGH); //Turn on LED delay(dot); //wait one 'dot' with LED on digitalWrite(LED,LOW); //Turn off LED delay(symbolSpace); //wait before the next symbol in a letter digitalWrite(LED,HIGH); //Turn on LED delay(dot); //wait one 'dot' with LED on digitalWrite(LED,LOW); //Turn off LED delay(symbolSpace); //wait before the next symbol in a letter digitalWrite(LED,HIGH); //Turn on LED delay(dot); //wait one 'dot' with LED on digitalWrite(LED,LOW); //Turn off LED delay(wordSpace); //wait before the next word } // (c) 2018 Let's Start Coding.
