首先,我们有led.value = True。这条线告诉LED点亮。在下一行,我们有time.sleep(0.5)。此行告诉CircuitPython将运行代码暂停0.5秒。由于这是在打开和关闭LED之间进行的操作,因此LED将持续0.5秒。 接下来的两行类似。 led.value = False告诉LED熄灭,time.sleep(0.5)告诉CircuitPython再暂停0.5秒。 然后在再次关闭LED...

The program will use the CPX's built-in light sensor to turn off the nightlight if the ambient light is strong enough. If it turns off, it will turn on the small red LED to let you know it's still working. But I found the turn-off feature needs to be calibrated per room, so ...
