This Arduino project lets the user send messages in Morse code via selection of text characters, by iterating through a table with them. Those characters are:
- The ASCII letters
- The cardinal numbers
- The Space character
- Placeholder characters for giving instructions: Erase character, Clear text, Send message
The user moves a joystick and presses it to select each character. Since there is no display, one of the LEDs blinks on/off depending on the preselected letter, according to a chess pattern. The other LED is the main one, and blinks according to the message itself.
The following components were used:
- 1 Arduino Nano
- 1 Joystick
- 2 LEDs
- 1 220Ω Resistor
- 1 1kΩ Resistor
