The goal of this project is to write a story about the design and building of a microcontroller-based dot matrix advertisement display. To begin, computer aided design is the modeling of physical systems on computers that allows for both interactive and automatic analysis of design variants as well as the expression of design in a manufacturing-ready format. Following that, the microcontroller-based dot matrix ad display is described as a gadget that is rapidly gaining wide acceptance and application in recent years due to its capacity to give extremely precise timing. The dot matrix ad display is an electro-mechanical system for processing data in which the data is represented by physical quantities that can only take discrete values, referred to as binary signals.
