Our theory/concept behind this topic, which is the three Es, being Electrical and Electronic Engineering, where we are required to create a handheld device for Speech-Impaired Patients as well as an Automatic Outdoor Light Controller with the detection of light. This way, we are able to create endless possibilities of circuits to be able to make it do practically anything. Learning the basic fundamentals of electronics enable us to have a head start in life, in the world of Circuits.
