raspberry pi led control

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

the power LED light on the small pie.Testing and ConfigurationIf you're using a Mac, all you have to do is open a terminal window and type the following command:Screen/dev/cu. pl2303-00001004 115200Screen/dev/cu. pl2303-00001004 115200The name of the device may be slightly different from mine. So when you type into "cu.pl", press the TAB key and it automatically complements your device name, and then type 115200 (this is the baud rate).If you are usi
