How I Learned to Code Arduino

How I Learned to Code Arduino at 16 — One Project, One Mistake, and One Discovery at a Time

Hi! My name is Abtin, and I’m a Grade 11 student at Handsworth Secondary School. Today, I want to share the story of how I started learning Arduino, a journey that began with curiosity, a book, and a couple of boards that completely opened my eyes to the world of electronics and programming.

Where It All Started

Like most students my age, I always wondered how the devices around me worked, phones, microwaves, sensors, even automatic doors. I knew there had to be a combination of hardware and code behind it, but I had never tried building anything myself.

That changed when I came across a book called:

“The Handbook of Arduino: 100 Projects by Example”

This book was packed with simple, real-world Arduino projects. As I read through the pages, something switched inside me. I thought:

“Why not try one by myself? How hard could blinking an LED be?”

Spoiler: a little harder than I expected… but worth it.

Ordering My First Arduino Boards

Once I decided to actually start experimenting, I ordered:

Arduino Uno R3
Arduino Pro
When the packages finally arrived, I opened them like they were treasure chests. Holding the boards in my hands felt unreal — like I had just unlocked a new level in my life.

Learning the Hard (and Fun) Way

At first, I had no idea how to code Arduino. I didn’t even know if I should learn Java, JavaScript, or something else. So I did what every teenager does:

I went online and searched everything.

I found tutorials, YouTube videos, GitHub repos, and forums. Some people used Arduino’s C/C++-based language. Others used libraries that connected Arduino to JavaScript via Node.js. Slowly, I realized:

Arduino isn’t about memorizing syntax — it’s about understanding how code controls hardware.

That was a turning point for me.

My First Working Project

My very first project was simple: making an LED blink.

Was it supposed to blink? Yes.
Did it blink the first time? Absolutely not.
Did I forget a resistor and nearly blow up the LED? Maybe…

But when I finally uploaded the code and saw that tiny light blink — on, off, on, off — I felt something I’ve never felt before.

It was control. It was creation. It was the start of a passion.
