将LED 阴极(短脚,平侧)接地脚;将正极(长脚)连接到限制电阻;然后将限流电阻的另一端连接到 GPIO 针脚(限制电阻可以连接到 LED的任意一侧)。 The following example will light the LED: 下面的示例点了 LED: from gpiozero import LED led = LED(17) led.on() Parameters: - 参数 pin (int or str) ...
Once you've setup your Raspberry Pi according to mygetting started tutorial, you are ready for your first real project. Let's light up an led using the Python programming language and the GPIO pins on your Raspberry Pi, hereafter calledRPi. What You Will Learn: You will construct a basic ...
**named_pins– Specify GPIO pins that LEDs of the board are attached to, associating each LED with a property name. You can designate as many pins as necessary and use any names, provided they're not already in use by something else. You can also specify LEDBoard instances to create tre...
In Push-Pull output mode, the GPIO pin will drive high level or low level actively. That means the GPIO can not only push the voltage to high level but also pull voltage to low level. This mode can provide powerful driver, which is suitable for load such as LED and motor. The most ...
In electronics, an analog-to-digital converter (ADC, A/D, or A-to-D) is a system that converts an analog signal, such as a sound picked up by a microphone or light entering a digital camera, into a digital signal. 在电子学中,模数转换器(ADC、A/D 或 A-to-D)是一种将模拟信号(例...
