[Day 4] Memory-Mapped Registers – Talking to Hardware Like a Pro
So far, we’ve been blinking LEDs and setting GPIO directions using high-level functions like digitalWrite() and pinMode(). But under the hood, your microcontroller communicates...
[Day 1] Embedded Simplified: What Really Happens When You Blink an LED?
When most people step into embedded systems, their first program is almost always the classic: Blink an LED. It feels simple enough—connect a board,...
[Day 6] Timers & Delays – How Microcontrollers Keep Track of Time
Ever wondered how your microcontroller knows how long to keep an LED on or how to blink it every second?
That’s the job of a...
[Day 0] Getting Started with IoT and Embedded Programming: A Beginner’s Guide
The Internet of Things (IoT) is no longer just a buzzword - it's a revolution that connects everyday objects to the internet, enabling automation,...
[Day 2] Understanding GPIO – Input, Output, and Pull-ups
When working with microcontrollers, one of the most fundamental tasks you'll perform is controlling GPIO (General Purpose Input/Output) pins. Whether you’re blinking LEDs, reading...
