Raspberry Pi Pico: Independent Control of 2 LEDs Using 2 Buttons (GP12-13 + GP4-5)

2 buttons, 2 LEDs — completely independent of each other! 🔴🟢 Each button controls its own LED: When BTN1 is pressed, the red LED turns on; when BTN2 is pressed, the green LED turns on. If you press both at the same time, both LEDs turn on (parallel operation). Learning: **multi-pin object management** (simultaneous handling of multiple inputs/outputs), **ternary operator** (`1 if x else 0` — Python’s compact if-else), **independent I/O control** (parallel operation logic), **GPIO map** (classic
