Interactive, animated walkthroughs of every ESE 123 lab, written by a TA for students who are new to electrical engineering. Each guide explains what you do, why it matters and how to do it step by step, with live simulations of the instruments, a formula sheet, practice questions and a report guide.
Safe power limits, the bench supply’s CV and CC modes, measuring a resistor’s I–V line and an LED that ignores Ohm’s law.
Volts, amps, ohms and continuity on the 34461A; KVL with stacked supplies; series and parallel; 2-wire vs 4-wire; how the meter loads a circuit.
Draw and solve circuits in LTspice (.OP, .DC), reduce a series-parallel network by hand, and solder your first parts onto the project board.
The generator’s hidden 50 Ω, RMS of sine, square and triangle waves, the 10:1 probe, and oscilloscope triggering.
Cursors and automatic measurements, sweeping an RC filter from 3 kHz to 1 Hz, phase, manual scope setup, bypass capacitors.
Design a −4.7 inverting amplifier, find where it clips, and test the board’s transimpedance current sensor.
Install the ATmega4809, program it in assembly with MPLAB X, count clock cycles, and turn delay loops into a 440 Hz tone.
Read the guide and play with the simulations. Predict your readings so you know when a measurement looks wrong.
Keep the formula sheet open. Each formula says when to use it and has a worked example with that lab’s parts.
Try the practice questions (new numbers, same ideas as the quizzes), then follow the report guide for each question.
Every page works on a phone. The text-only README version of each lab is on GitHub too.
Made for ESE 123 students by a TA. These guides add to the official handouts on Brightspace and don’t replace them; if anything differs, follow your handout and your TA. Simulated values are typical; your bench readings will differ a little.
