Chapter7 :부저¶
1.Preparation¶
1.You should learn about the position of the buzzer in the body of hellobot;
3.You should learn about the micro:bit pins connected to the buzzer in the schematic.
4-1-1 buzzer on arm of hellobot
4-1-2 schematic
4-1-3 Pins of Micro:bit
From the schematic diagram in P4-1-3, you can see that the touch magic lights is connected to the P0 of the Micro:bit. You can use the blocks of music directly.
