Project: Making an Alarm Clock That Asks Question Randomly

Introduction: I got two very interesting small modules from DFRobot, one is the speech synthesis module and the other is the speech recognition module.
I will make a slightly gentler one here. An alarm clock with random questions. It will stop making noise if the answer is correct; if the answer is incorrect, it will keep annoying you.
