Pin distribution

• Novice users do not need to remember the corresponding pins of the Port, just remember to use the Port.
• To use the Port5 - Port7 port, you need to turn off the LED dot-matrix screen function (as shown below, turn off the LED dot-matrix operation) in order to use
• Port4 has no analog reading function (temperature and humidity soil water level magic block cannot be used) (because the Port5-Port7 pins are multiplexed with the Microbit dot matrix screen)
