Morse Code is a way of encoding written letters as sequences of dots and dashes. Developing a Morse Code application can improve programming skills. A simple Morse Code application will convert text to Morse Code, send it as an audio message using Twilio, and expose the locally running application to the internet using Ngrok. Before diving into the code, ensure Go 1.22 or above is installed, along with a Twilio Account, Ngrok, and a Twilio phone number. The project covers creating a web app that listens for HTTP requests, decoding Morse Code messages, triggering a phone call where the recipient can hear the Morse Code as an audio message. It also involves configuring a Twilio phone number to respond to incoming voice calls, creating a function to convert text to Morse Code, and utilizing TwiML to generate audio tones for the Morse Code. The project sets up a new Go module, installs required dependencies, downloads beep sound audio files, exposes port 8080 on the local machine using Ngrok, sets up environment variables, builds the project by defining imports, defining TwiML structures, implementing Morse Code conversion, and creating HTTP handlers and the main function. Finally, it creates an HTML form for user input and runs the application to initiate a phone call with the provided message in Morse Code.
