如何才能让故障灯闪烁以不同的音乐?
- 使用 LED blink library。
- 使用 Timer 类。
- 使用 Web Bluetooth API。
LED blink library
import time
import random
class LEDBlink:
def __init__(self, led_pin):
self.led_pin = led_pin
self.blink_duration = 1000 # 1 second
self.stop_blink = False
def start(self):
while not self.stop_blink:
self.led_pin = True # Turn on the LED
time.sleep(self.blink_duration)
self.led_pin = False # Turn off the LED
time.sleep(self.blink_duration)
# Example usage
led_pin = 17 # Replace with the actual LED pin
led_blink = LEDBlink(led_pin)
led_blink.start()
Timer
import time
# Set the blink duration
blink_duration = 1000
# Start a timer for the blink
timer = time.Timer(blink_duration, lambda: print("Blink!"))
timer.start()
Web Bluetooth API
import websockets
# Connect to the Web Bluetooth API
ws = websockets.create_websocket("ws://localhost:80/websocket")
# Send a message to the server
ws.send("Start blinking!")
# Receive the server's response
message = ws.recv()
# Print the message
print(message)
注意:
- 这些代码示例仅供参考,您可能需要根据您的硬件和软件环境进行调整。
- 确保 LED 是正常工作的,并与您的代码运行在相同的设备上。
- 您可以根据需要修改音乐播放的频率和节奏。
