I've also attached a picture of dots and dashes for every alphabet in this Instructable. Note: I've attached a demonstration video at the end of this Instructable, you can use the video as a model to see if your decoding device functions normally. In order to differentiate every alphabet, you must wait for at least a second after you inserted the first few dots and dashes for your first alphabet. After inserting the dots and dashes of the alphabets, your computer will then translate the morse code into alphabets in the Arduino Serial Monitor window. If the sound lasts for only a second, then it's a dot. Similar for the buzzer, if the sound continues for a while, it's a dash. On the other hand, if the LED only flashed for a second, then it's a dot. If the LED lights up for a while, it's a dash. Once you push the button, the LED will light up and the buzzer will make a sound to notify you whether you inserted a dot/dash. Take note that you must open the Arduino Serial Monitor window while inserting your Morse Code by pushing the button. Throughout this Instructable, I will teach you how to make a decoding device that provides longer intervals between each dash/dot, audio aspect to differentiate dash/dots, and sufficient time for Morse Code beginners to memorize the dash and dots of an alphabet. However, this product was designed to create a friendlier environment who are Morse Code beginners trying to learn Morse Code and to provide a more detailed demonstration of how Morse Code applies to sound and light. This product was inspired by "Morse Code Decoder" created by pinkai_s91 on Instructables, which is available through the link.
