From Motorola 68000 to Arduino: Rediscovering My Passion for Embedded Systems| 重拾電子樂趣的嵌入式新旅程
My Journey into Embedded Systems | 我的嵌入式系統學習之路
I studied Electronics back in my polytechnic and university days, and I’ve always had a keen interest in how circuits come alive to make things work.
Back then, the popular microcontroller was the Motorola 68000 — a legendary chip used in many industrial and computing systems.
To be honest, I don’t even remember if we called it “embedded systems” at that time — it was just “microprocessor programming.”
Years later, I’ve decided to revisit that passion and rediscover this exciting field.
Embedded systems today have evolved far beyond what I studied — they’re now everywhere: in smart homes, wearables, drones, and even aircraft systems.
To begin my journey, I’ve purchased several development kits representing the major platforms used today:
- Arduino — beginner-friendly, open-source, and perfect for quick experiments like blinking LEDs or reading sensors.
- STM32 — professional-grade microcontrollers used in real-world products, fast and feature-rich.
- ESP32 — Wi-Fi and Bluetooth built in, perfect for Internet of Things (IoT) projects.
- Raspberry Pi — not just a microcontroller but a small computer, great for robotics, vision, and AI.
Right now, these kits are neatly arranged on my desk, waiting for their first “power-up.”
My plan is to start small, learn step by step, and record the process here — both my mistakes and small victories.
In a way, this feels like reconnecting with an old friend.
Same curiosity, new tools, and endless possibilities ahead.
老實說，我跟「嵌入式系統」的緣分可以追溯到很久以前。
我在理工學院和大學念電子工程的時候，當紅的是 Motorola 68000。
那時候哪裡有人說什麼「嵌入式」？大家只會說「微處理器」—— 用組合語言寫一堆讓人頭大的程式。
幾十年過去了，我又想「玩回電子」。
只是現在的世界已經完全不同了——
一顆小晶片就能上網、測溫度、控制機器人，還能跑 AI。是不是很誇張？
所以我也忍不住手癢，買了幾套開發板：
🟢 Arduino：最親民的小板子，適合暖身。
🔵 STM32：真正工程師的選擇，要動腦但有成就感。
🟠 ESP32：有 Wi-Fi、有藍牙，IoT 全靠它撐場。
🍓 Raspberry Pi 樹莓派：其實是台小電腦，能玩影像、AI、還能連相機。
目前它們都還乖乖地躺在桌上，我還沒正式「開工」。
但光看到那幾個 USB 線和排針，我就覺得回到學生時代的實驗室一樣。
這個部落格，就當是我重新拾起電子樂趣的記錄。
有時會寫筆記，有時可能只是碎碎念。
希望你也能從中找到一點「動手玩」的樂趣。
