電子裝置 – 摩斯密碼

I’m already sending my first message in Morse code to a friend after just one evening with this guide. The hands-on circuit exploration makes the dot-and-dash system finally click for me. It’s a clever, practical way to learn something genuinely useful.

The history section is interesting and the dots-and-dashes breakdown is clear enough for a beginner, but the hands-on circuit exploration feels thinner than I hoped for. It works fine as a basic reference, though I wish it went deeper into actual electronic device use.
