📟 Morse Code Encoder/Decoder 🛠️ Project Overview This Arduino sketch lets you encode and decode Morse Code!

🔹 Decode by keying in Morse sequences with a button. 🔹 Encode by typing letters into the Serial Monitor. 🔹 Watch the LED flash and listen to the buzzer beep as the code is processed.

This project is inspired by the book "Programming Arduino" by Simon Monk (©2016), with some code lines adapted from there.

🔧 Components Needed

🔹 Arduino board 🔹 Piezo buzzer or speaker (connected to pin 2 & ground) 🔹 Button (connected between pin 8 & ground) 🔹 LED (positive leg to pin 13, negative leg with 220Ω resistor to ground)

💡 Features

✅ Encode letters and numbers to Morse Code. ✅ Decode Morse Code sequences using a button. ✅ Plays a sound and flashes an LED during transmission. ✅ Unrecognized sequences give a warning beep and show ?. ✅ Includes a demo that flashes JONOK in Morse Code at startup.

⚡ Usage Instructions 1️⃣ Upload the sketch to your Arduino board. 2️⃣ Open the Serial Monitor (9600 baud). 3️⃣ To Encode:

Type a word or number, press Enter, and watch it convert to Morse Code.

4️⃣ To Decode:

Press the button for short taps (.) and long taps (-). The LED and buzzer will activate. A short pause signals a new letter, and a longer pause signals a new word.

5️⃣ Practice:

Type a word in the Serial Monitor. Listen and try to replicate the sound with button presses.

🚀 Tip: Adjust the Morse speed with dotLength (default = 240 ms, ~5 WPM).

🔥 Demo Output On startup, the LED blinks and the buzzer sounds JONOK in Morse Code: J .---
O ---
N -.
O ---
K -.-

🧠 Future Improvements

🔹 Add support for punctuation. 🔹 Implement adjustable speed via Serial input. 🔹 Save decoded messages for later.
