![]() 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.
