I made this just for fun, and it was also very fascinating to think about how a person can communicate with anyone only by using three keys. The first switch on the transmitter device is used for sending the Dot signal, the second is used for Dash, and the third is for enter/space. The morse code translates to English automatically on the receiver end, and if a wrong combination of dot and dash is received then the screen says Invalid!. The primary purpose of this project is to practice morse code, and it can also be used to send messages to a person in close proximity. After building this project, I had an idea about a possible application of these devices in which the transmitter can be used by people who are differently abled. Maybe it can somehow be used by them in such a way that whatever they send gets converted to text or even voice.
