Course Overview

Welcome!

Welcome to ECE 445! If you've looked at the course Calendar, you've probably already noticed that this class is quite different from most other classes in the department. The class only meets as a whole for the first few weeks of the semester. During these lectures you will meet the Course Staff, learn about specific assignments, requirements, and resources for the course, and have a chance to meet other students to share ideas and form teams. These are some of the most important weeks for the class since the decisions you make during this time will determine what you'll get out of this class and, in many ways, how much you'll enjoy it.

Outside of lecture, you are expected to be working on your own to develop ideas and form teams. You are also expected to actively participate on the web board to exchange ideas, receive feedback from course staff, and eventually get your project idea approved. Once your team has a project approved, you will be assigned a TA, with whom you will have weekly meetings. Think of your TA as a project manager. Keep in mind that they are not there to do the work for you. Rather, they are there to keep you on track, point you towards resources (both within and outside of the department), and evaluate the result of your efforts.

Expectations and Requirements

We have high expectations for students participating in ECE 445. You are soon to be alumni of one of the top ECE departments of the world. Our alumni hold themselves to high technical and professional standards of conduct.

In general, projects are expected to solve an interesting problem within the constraints of the course. You will discuss the motivation for your project and its societal impact. What are the potential benefits and possible negative consequences of your project? What engineering standards are applicable?

Your projects are expected to be safe and ethical, and to satisfy applicable ethical codes developed by professional societies such as IEEE or ACM. Previous projects have covered a wide range of topics in areas of personal convenience, entertainment, medical research and treatment, personal transportation, music, robotics, and industrial processes, to name a few.

Projects are expected to have a level of design complexity commensurate with the rigor of the ECE Illinois curriculum. Requirements for specific assignments due throughout the semester can be found by looking through the Grading Scheme for the course. Please read through this documentation well before each assignment is due. Specific due dates can be found on the course Calendar.

Below are a few words of wisdom to keep in mind throughout the semester to increase your enjoyment and success in the course:

Featured Project

# Champaign MTD Bus Tracker Map

# Team Members:

- Amber Wilt (anwilt2)

- Daniel Vlassov (dvlas2)

- Ziad Aldohaim (ziada2)

# Problem

Champaign has a very large and complex bus system through the MTD. It can be hard for students to know when the buses are coming when they are in buildings such as the ECEB, since the bus times are only displayed at the stops. Furthermore, these buses can be late or early, causing students to miss their bus or not arrive at their destination on time.

# Solution

To fix this, we will come up with the design for a large display that shows real-time locations of all buses (color-coded using RGB) in the surrounding campus area. This can be used by students in buildings to easily visualize where the bus they want to take is currently located, making it easier for students to time when to leave classrooms and when to expect their ride. The display will update the locations approximately every 30 seconds and will light up every LED along a bus route every few minutes to make it easier for students to visualize which bus route they need to take. Furthermore, the system will include various light settings (theme/brightness).

# Solution Components

This system will mainly include the subsystems of the LED matrix, the controller, and the power supply.

## Subsystem 1 - LED Matrix

The LED matrix will be located on a large PCB or 3D printed map of the city (cost dependent). This subsystem will be made of addressable LEDs, photoresistors to automatically modify the intensity of LEDs, and will be controlled by the microcontroller (to indicate positions).

## Subsystem 2 - Microcontroller

The microcontroller will utilize wifi to access the MTD API to gather real-time bus data as well as provide control to individually address each LED within the matrix. Furthermore, it will control/communicate with other modules/displays in the system, such as a real-time clock or menu. The microcontroller will be an ESP32

## Subsystem 3 - Power Supply

The power supply will provide ample power to a large number of LEDs (and the entire system). We will need to include a buck converter to step down the power supply to be usable by the LEDs.

# Criterion for Success

To demonstrate the success of our project, we will need to prove the accuracy of the data we are displaying (how accurate are bus timings/locations). Additionally, we will need to show that the data is easy to interpret for a user and can be utilized for easier bus system use.
