Morse Code Communication with RF24 on Raspberry Pi Pico

Project Overview

The ultimate goal of this project is to enable Morse code communication between two Raspberry Pi Pico boards using the RF24 module.

Project Development Progress

In this update, we will integrate 3 buttons for sending, along with a buzzer and an SH1106 OLED display for outputting and displaying the content.

To clear the screen, press BUTTON_SEND 3 times.
