Introduction

● The purpose of the project was to

demonstrate all the knowledge we have

learned from the beginning of the

semester.

● Groups were told to invent a music source

docking station with a treble and bass

speaker .

● During the entire process lab GTA was

carefully guiding students through each

component of the project

● If students had a good understanding of

the matter the project was not posing

many difficulties

● The process of distinguishing whether a

component is in the right place, gave the

students a greater understanding of the

overall topic of the course
