Flashing Lights`: How to Build a SMS to Morse Code Translator with a Particle Electron and Twilio The article discusses how to create an SMS-to-Morse code translator using a Particle Electron, Twilio, and the Particle Cloud REST API. The project involves connecting the Particle Electron's hardware components, such as the SIM card, cellular antenna, and battery, and then writing Python code to handle incoming SMS messages from Twilio. The code sends the Morse code translation to the Particle Electron via the cloud API, which blinks an onboard LED with the corresponding dot or dash sequence. The article also provides instructions on how to set up a Flask server to run the application, expose it to the public using ngrok, and update the firmware for the Particle Electron.
