LED Blinking
This code demonstrates how to make an LED blink on and off at a 1-second interval using the digitalWrite() and delay() functions.
The circuit:
- LED attached from pin 11 to ground
Diagram:
Arduino LED

| 13 |-----|>|---+---- GND
| | (Anode) (Cathode)

LED Blinking
此代码演示了如何使用 `machine.Pin` 类和 `time.sleep()` 函数使连接到 GPIO2 引脚的 LED 每隔 1 秒闪烁一次。
电路连接：
- LED 连接到 GPIO2 和地线（GND）
