Phase 01: The Pulse of the System (Blink) ⚡️
Concept Every journey into hardware begins here. This is the "Hello World" of electronics—the first proof of life. While deceptively simple, this phase is critical: it validates the entire toolchain, from the code editor to the physical silicon. It confirms that we can successfully compile logic, upload it to the microcontroller's memory, and manipulate physical electricity through software commands.
The Tech Stack
- Hardware: Arduino Board (Internal LED on Pin 13).
- Logic: Digital Output Control & Timing.
- Objective: Create a visual "heartbeat" to verify system integrity.
How it Works The code interacts with the microcontroller's General Purpose Input/Output (GPIO) registers.
- Initialization (
setup): We explicitly instruct the microcontroller to treat specific pins as OUTPUTS, preparing them to deliver voltage rather than read it. - The Infinite Loop: We drive the pin HIGH (sending 5V) to illuminate the LED, pause the processor execution for 1000ms, and then drive it LOW (0V) to extinguish it. This cycle repeats indefinitely, creating the blink.
AI Context 🤖 Even in this fundamental step, AI played a role in optimizing the workflow—generating clean, commented boilerplate code and explaining the underlying register logic, ensuring best practices from line one.
Status ✅ Operational | The system is alive and responding to commands.
