我想将防暴开关(CPS)与 Raspberry Pi 连接,我想在按下按钮时通过 Phython 程序注册并将 LED 灯从蓝色变为红色。
我如何将电缆连接到 Raspberry Pi:
Brown cable -> 5V Power
Black cable -> Ground
Black cable -> Ground
white cable 1 -> GPIO5
White cable 2 -> GPIO6
Green cable (green LED) -> GPIO2
Blue cable (blue LED) -> GPIO3
Red cable (red LED) -> GPIO4
我在 Raspberry Pi 上的 phyton 中尝试过这个:
from gpiozero import Button, LED
from signal import pause
led = LED(3)
button = Button(5)
button.when_pressed = led.on
button.when_pressed = led.off
pause()
错误:没有名为“gpiozero”的模块
我已经通过控制台命令安装了模块:
sudo apt update
sudo apt install phyton-gpiozero
(它说它已经在最新版本上)
