Goals

ECE 110 is a freshman engineering course.

Computer Usage

All course materials are available via the Internet. Homework problems are primarily computer graded but often some subset are hand graded through a scanned submission on GradeScope. All exams given at the Computer-Based Testing Facility (CBTF). Students must be able to use a Web browser and have adequate access to the Internet. Course provides some basic aspects of scientific computing for data analysis and physical computing for hardware interaction.

Reports

Short lab reports are due for each of the approximate 9 weekly procedural labs, plus a project proposal and final report.

Lab Projects

Thirteen weekly lab meetings lead students from breadboard basics through electronic design.

All labs are designed with team collaboration elements to build community within the student body (3, 5). The students work in pairs and generate reports for grading (3). The lab also includes self-selected modules that aid in solidifying principles in electronics (1), aspects of professional behavior and ethics (4), analysis and interpretation of electronic solutions (6), and exploration beyond the standard course material (7).

By the end of lab 2, students will know how to use basic DC equipment to build and measure circuits with batteries, power sources, motors, and resistive networks (1). They begin to apply simple circuit models for batteries and motors (6).

By the end of lab 5, students have applied Kirchhoff’s voltage and current laws to DC circuits as well as built time-varying circuits and making observations on the oscilloscope (1). They explore increased efficiency and torque gained by using pulsed-motor drives (6).

By the end of lab 7, students have improved their model of the DC wheel motor and constructed Pulse-Width-Modulated generators (1) and analyze this efficient motor drive (6) that is no longer tethered to the benchtop function generator (2).

By the end of lab 9, students have added controls for both overall speed as well as differential wheel speed (1, 2). They have also built the cars to be fully autonomous wall-following vehicles (1). Further, they are trained to pay attention to design layout to improve debugging as well as reduce the likelihood of failure (2).

By the end of the final project, student teams will prepare a project proposal that includes a problem statement, proposed solution and timeline, and an itemized list of required parts (2, 6, 7). They will document the progress of their project while demonstrating teamwork and time management and present the working project while discussing the technological challenges and solutions (3, 5, 6). Finally, they prepare a properly-formatted final report (3, 5).

Course Goals

ECE 110 is a freshman engineering course. Its underlying intent is to excite students about the study of electrical and computer engineering by enhancing their problem solving skills through analysis and design and exposing them early in their education to individualized electronic design projects.

The goal of the ECE110 freshman engineering course is to introduce students in their freshman year to the electrical devices and circuits used in modern power and information systems and to simultaneously develop basic modeling and analytical skills that are used to analyze and design such systems. The devices are taught in a historical context, and, for the most part, the analytical skills are limited to simple algebraic and geometric techniques. It is a 3 credit hour lecture/laboratory course in which students learn about electrical instruments, motors and generators, diodes, transistors, amplifiers, digital circuits, microprocessors, sensors, feedback control, and power and information systems. In the lecture the students learn (1) how a number of electrical devices and systems work, (2) how to construct simple mathematical behavioral models for these devices, and (3) how to design and perform simple analyses of circuits and systems containing these devices. In the laboratory the students experiment with procedures utilizing these devices, and in the final four weeks of the laboratory student teams complete a design. The design is often open-ended and student-defined, but it must showcase the lab skills they have been trained for: measurements, modeling, analysis, and design with feedback. Supply-chain issues sometimes results in a final project that is more-limited in structure based on the available materials.
