Electrical Lab
This laboratory course is designed to be the experimental companion to ESE 216 Electrical Circuits and Systems II. The course is intended to enhance the students' understanding of important analytical principles developed in EE 216 by engaging them in the real-world application of these principles in the laboratory. An equally important purpose of the course is to further develop the students' laboratory practice for experimentally testing and evaluating electrical circuits and systems. It is important that students develop this practice using modern lab equipment similar to that which is used in industry. Due to computational power of PCs; they are being increasingly used to acquire experimental data, to control laboratory instruments, to process experimental data, and to provide a highly flexible means for visualizing experimental data. For most of these functions the PC is providing real-time or near real-time support. LabView by National Instruments is one of the most popular software tools for these purposes. It is also a useful tool for analysis, with some functions similar to MatLab. It is one of a core of staple software tools for electrical engineers, as are Maple, MatLab, Electronics Workbench and SPICE.

Stepper Motors
This hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 670 mA at 4.5 V, allowing for a holding torque of 950 g-cm (13 oz-in). The motor has four color-coded wires terminated with bare leads: black and green connect to one coil; red and blue connect to the other. It can be controlled by a pair of suitable H-bridges (one for each coil), but we recommend using a bipolar stepper motor driver.
Our 5mm universal mounting hub can be used to mount objects on the stepper motor’s 5mm-diameter output shaft.
