1.1 Methods of Graphical online programming
1.First connect the micro:bit to the computer with the data cable. At this time, the computer will have a micro:bit U disk. Open the USB flash drive and click on the micro:bit URL as shown in Figure1-1 below to enter the micro:bit official website. You can enter this web address directly in your browser: http://microbit.org/.

10.You can build your own building blocks for programming. After setting up the program blocks, we can set a name for the program, and then click 【Download】 to download the program, as shown in Figure 1-11. We can set the download path to a micro:bit U disk, or you can download it directly to your computer and copy it to the micro:bit U disk.
