**Title:** Spectrophotometer/colorimeter project (F.22. BME 490A)
-----------------------------------------------------------------

----------
**Description:** The following materials/resources are shared to enable other educators/students to adopt the spectrophotometer projects for their courses.
For a brief description of the fundamentals of spectrophotometery please review reference 1. Alternative implementations can be accessed from references 2-7.
**Note-1:** A corresponding TinkerCAD simulation (circuit and code) was developed available from: https://www.tinkercad.com/things/b3yvnGdOEXo?sharecode=iazcBxnUvZOFOb4jcGjxx2NXMnR1xhdVm4AqLylH2jo
**Folder Mechanical hardware example** includes sample designs from teams (F.22).
Group-1 (G1) developed cuvette holders, a lid/cap for the cuvettes (i.e., they called the system cuvetter), and a box. Files shared by Erika Gomez on behalf of the team.
Group-2 (G2) developed a holder for both circuit and cuvette, a box to block ambient light, and guides to align LED and sensor. Files shared by Max Bueno on behalf of the team. Team members: Max Bueno, Karlyle Soliven, Evan Garner, Joel Mendez, and Nicko Villafuerte.
