:).-----------------------------to spit out the installation experience-----------------------------------------------------Today, there is a project to do a self-running measurement system, thinking about how to implement automatic measurement when not connected to the PC. The previous day has been the Python GUI, so think of the idle raspberry Pi, perhaps with an HDMI monitor can be used. Friday, while pl

Yesterday made the control led, played the first, the rest of the feeling is very simple, here recordJust a couple of photos.Play the honey module only to find the law, generally this module, there will be three pins, VCC (3.3V or 5V power supply output PIN), GNC (for Gpio pin of GNC), out/(I/O) (corresponding to the gpio number of pins), if it is necessary to send information to the

Raspberry PI Series--bare metal illuminated LED lightsBackgroundRecently just bought Raspberry PI B +, configured to run the official Raspbian system, tossing a week Linux system, feel no meaning, so try to understand the bottom of the start process, through a few days of research, It is found that the boot of the lowe

prove that Snappy is a system for cloud computing, especially for Iot. Snappy can also run on other clouds such as Amazon EC2, Microsoft Azure, and Google's Compute Engine. It can also be virtualized on KVM, Virtuabox, and vagrant. Canonical Ubuntu has embraced heavyweight players such as Microsoft, Google, Docker, and OpenStack, and has reached partnerships with small projects. In addition to some startups, such as Ninja Sphere and Erle Robotics, th
