raspberry pi 3 python

Recently, I bought a Raspberry Pi 3b+, ready to put a. Net core crawler on it and run it.Buy before thought Raspberry Pi because it is new this year, leading to drive and system what is not very perfect, led to go a lot of detours, early know to buy Raspberry

Color control for RGB LEDs with Raspberry Pi RGBColor Modeis a color standard for industry. is through theRed (R),Green (G),Blue (B)Three ColorsChanneland they overlap each other to get a variety of colors, RGB is the representativeRed,Green,Bluethree channels of color. This standard almost contains all the colors that human vision can perceive, and is now the most widely usedColor System one of them. Th

positioned next to each other on the PI settings. But in later versions of the Raspberry Pi, these interfaces are in the middle of the Gpio, which is a bit difficult (in case of poor eyesight or the fiber is too dark, it is hard to see). I usually put my own PI traffic light on the 13, 19, 26th Gpio interface and GND

Windows 3.1 is running on a Raspberry Pi, and you naturally want to run Windows 10. So you're ready to install a system of Windows IoT core on the Raspberry Pi. When writing this text, it's not the first time that you've installed Windows IoT core. After I got the Raspberry

Starting with the Windows IoT Core 14986 release, Microsoft has added the Cortana voice assistant feature. Before, we could only use local speech recognition, and we needed to write the application to download it to the device. From now on, Microsoft has integrated the Cortana voice assistant from the system level, enabling users to start Cortana and interact with Cortana in real time with system settings. Let's try the process of using Cortana as a Windows IoT core device with
