ENGR 120 - Required Hardware and Software

The freshman curriculum, called Living WITH the Lab, provides a boost in hands-on learning by putting the ownership and maintenance of the “lab” into the hands of the students. Each student will purchase a robotics kit with a programmable controller, sensors, servos, and software to provide the basis for a mobile laboratory and design platform. Students will also purchase tools and software to allow them to work on projects independently outside of the classroom. Student-owned hardware and software broaden the spectrum of projects and design topics that can be addressed.

The items purchased for ENGR 120 will be used throughout the ENGR 120, 121 and 122 course sequence. Student should order their Boe-Bot parts kit, Arduino, breadboard, USB cable, multimeter, and mini test clip adapters well before classes begin to avoid "backorder" or "out of stock" problems. Students will need the other tools by the middle of the quarter.
