L2 Task 1: LED blink implementation

[akhilaryan007]

Implemented Level 2 Task 1: LED Blink Application using Zephyr RTOS within the zephyr-course workspace.

The application configures an LED using the device tree alias led0 and toggles its state every 1 second. The implementation leverages Zephyr’s GPIO abstraction (gpio_dt_spec) for hardware-independent configuration and control

Implementation Details :

1. Used Device Tree alias (DT_ALIAS(led0)) to access LED hardware
2. Initialized GPIO using:
3. gpio_is_ready_dt() for device readiness
4. gpio_pin_configure_dt() for output configuration
5. Implemented LED toggling using:
6. gpio_pin_toggle_dt()
7. Introduced delay using:
8. k_msleep(1000) for 1-second interval
9. Integrated logging using Zephyr logging subsystem:
10. Logs LED state (ON/OFF)
11. Confirms execution with status message

Testing :

Successfully built using Zephyr build system
simulated with the native_sim
Verified:
LED toggles every second
Console logs reflect correct LED state
