Making a security device

I’m making a security device for my school project.It is a small box with gyro sensor,light sensor and buzzer.I have no knowledge on Arduino and programming.I’ve created this basic schematic on how will the gyro sensor,light sensor and buzzer to be connected.The gyro sensor and light sensor will be the input and the buzzer is the output.Sorry for the bad English.Please help me to check if it is connected to the correct pin.

Welcome in Arduino land,

Connected to the right pin depends on the code as the SW and HW must be "in sync"

Thanks alot and which header should i connect the 9v pin the arduino mini?
