使用Python 控制 GPIO 使用GPIO Zero 库可以轻松地用 Python 控制 GPIO 设备。该库在 gpiozero.readthedocs.io 上有全面的文档说明。 有关GPIO 硬件的信息,请参阅 GPIO 硬件。 LED 控制 以下示例代码可控制连接到 GPIO17 的 LED: from gpiozero import LED from time import sleep led = LED(17) while True...
目前打算由潛入深慢慢學習RaspBerry Pi, 所以先由最容易下手的Python進入樹莓派的世界 首先要使用 GPIO 需要利用RPI.GPIO package想當然爾必須先安裝 所以先執行下列命令進行安裝 sudoapt-getinstallrpi.gpio 則可以使用的IO可以透過下列命令檢查, 可以得到IO相關狀態 gpio readall 最後附上GPIO H/L的簡易程式, 相關說...
There are several ways of getting GPIO input into your program. The first and simplest way is to check the input value at a point in time. This is known as 'polling' and can potentially miss an input if your program reads the value at the wrong time. Polling is performed in loops and...

现在使用一个电阻来将阴极连接到负电源轨。使用电阻很重要,否则LED将会使用过大的电流从而烧坏您的Raspberry Pi。 测试红色LED 首先启动Python解释器,输入: python3 让我们加载RPi.GPIO,并设置引脚编号模式,请记得Python对大小写很敏感。 import RPi.GPIO as GPIO ...
This tutorial is about a simple Traffic Light Circuit using the programmable GPIO Pins via Python. In the next tutorial, we will extend the circuit by a few functions (including an Input). Accessories We need the following: Breadboard*
GPIO stands for General Purpose Input Output. The Raspberry Pi has two rows of GPIO pins, which are connections between the Raspberry Pi, and the real world. Output pins are like switches that the Raspberry Pi can turn on or off (like turning on/off a LED light). But it can also send...

Hardware & GPIO How to create a Solar Powered Raspberry Pi Bitcoin Miner Everyone has been talking about cryptocurrencies for some time0. They can not only be used as a means of payment but can also be generated using your own computing power. Therefore, it is also possible to operate Bitco...
Now that we have added the sethigh(), setlow() and makeoutput() methods to our module, we will modify the Python script in the project to actually call them. However first we need to find a pin that we will control. According to theRaspberry Pi 2 pinout, GPIO pin #3 is the lower...
