:).-----------------------------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

linux applications. the reason is very simple. perl is fading out, ruby is not powerful, shell is not enough, php is not suitable, and java is not explained. I remember that the Redhat 7 character interface installer was written in python, which was almost the first time I heard about python. it was very powerful, easy to use, and easy to modify and adjust. Don't waste time and energy on things unrelated

logic. Yesterday my wife read the Rpi.gpio document, one hours and dozens of lines of code can be achieved by the Raspberry Pi car through the infrared detector tracking operation. It's something that no other language can do or that's hard to do. Video stamp here: Raspberry Pi Infrared Tracking trolley
