+
+## 簡單範例
+
+```python
+import asyncio
+from dglabv3 import dglabv3
+from dglabv3 import Channel, StrengthType, Pulse
+
+
+client = dglabv3()
+
+
+async def run():
+    try:
+        await client.connect_and_wait(timeout=30)
+        print(client.generate_qrcode_text())
+        await client.wait_for_app_connect(timeout=60)
+        client.set_strength_value(Channel.A, 20)
+        await asyncio.sleep(1)
+        client.send_wave_message(Pulse().breath, 30, Channel.A)
+
+    except Exception as e:
+        print(f"An error occurred: {e}")
+        exit(1)

+
+if __name__ == "__main__":
+    asyncio.run(run())
