Code

For C Language User

Go to the code folder compile and run.

cd ~/Basic-Starter-Kit-for-Raspberry-Pi/c/3.1.2/
gcc 3.1.2_MorseCodeGenerator.c -lwiringPi
sudo ./a.out

NOTE: If you want to check the complete codes, you are suggested to use command `nano 3.1.2_MorseCodeGenerator.c` or `nano 3.1.2_MorseCodeGenerator.py`.

For Python Language User

cd ~/Basic-Starter-Kit-for-Raspberry-Pi/Python/
python 3.1.2_MorseCodeGenerator.py

After the program runs, type a series of characters, and the buzzer and the LED will send the corresponding Morse code signals.
