1. Learning objectives
Control the buzzer switch on the expansion board.
2. Experimental preparation
As shown in the figure below, the buzzer is an onboard component, so no external devices are required.
3. Core code analysis
The buzzer on the expansion board is an active buzzer, please refer to the following function.
Raspbot_Lib library function required to control the buzzer:
xCtrl_BEEP_Switch(state)
Parameter explanation: Control the buzzer switch
state=0: off, state=1: always ringing.
Return value: None.
Source code path: project_demo/03.Basic_car_course
4. Experimental phenomenon
Turn on the robot, open the computer browser to enter the Jupyter lab editor
Enter the source code path, double-click the code to be run
Restart the kernel and clear all outputs
Click the first code block, then click the run button to start running one by one
After the program runs, as the code block runs, we can turn on or off the buzzer
