Requires an Arduino Uno, LED, buzzer, resistors, and jumper wires plus the Arduino IDE.
This is a small student project that demonstrates how to send and receive Morse code using an Arduino microcontroller board. Morse code represents letters and numbers as short and long signals, traditionally called dots and dashes. The project converts typed text into these Morse signals, transmits them using an LED light and a buzzer, and can also decode incoming Morse signals back into readable text. The idea behind it is to show real time signalling that could be useful in situations with very limited communication bandwidth, such as emergencies, where a simple blinking light or beeping sound is enough to get a message across without needing a full data connection. The hardware used is straightforward and inexpensive: an Arduino Uno board, an LED, a buzzer, along with basic resistors and jumper wires to connect everything, programmed through the Arduino IDE, the standard software used to write and upload code to Arduino boards. The README describes this as a learning project, built for a college project expo. The author notes that the idea was inspired by existing online tutorials found on YouTube and other Arduino resources, and that they adapted and customized the approach for their own learning rather than designing it from scratch. The presentation template used alongside the project belongs to the author's college, St. Joseph's Institute of Technology. There is no mention of a license in the README.
A student Arduino project that encodes text into Morse code and transmits it using an LED and buzzer, then decodes it back.
Mainly C++. The stack also includes C++, Arduino.
Setup difficulty is rated moderate, with roughly 1h+ to a first successful run.
Mainly general.
