Hello World — First Post on imadestuff

Welcome to imadestuff

This is the first post on imadestuff.com — a place where I document the things I build, break, and learn along the way.

To kick things off, here’s the classic “Hello World” of electronics: a blinking LED on an Arduino.

The Circuit

Wire up an LED to pin 13 on your Arduino Uno with a 220Ω resistor. That’s it. Simple as it gets.

The Code

Here’s the Arduino sketch in C++:

const int LED_PIN = 13;

void setup() {
  pinMode(LED_PIN, OUTPUT);
}

void loop() {
  digitalWrite(LED_PIN, HIGH);
  delay(1000);
  digitalWrite(LED_PIN, LOW);
  delay(1000);
}

Upload that to your board and you’ve got a blinking LED. Not bad for a first post.

Why Start Here?

Every maker I’ve ever talked to started with a blinking LED. It’s the smallest possible proof that you can make hardware do what you want. One LED, one resistor, five lines of code, and you’ve crossed the line from “person who reads about electronics” to “person who builds electronics.”

From here? Sensors, motors, displays, sounds. But this is the moment it starts.

Here’s a great intro to Arduino for anyone just getting started:

What’s Next

Expect posts about retro computing builds, robot attempts, game prototypes, AI experiments, and whatever else I end up making. This is a blog about doing things — especially the messy, imperfect first attempts. Stay tuned.
