Abstrakt:	Learn how to build a Closed-loop Spectroscopy Lab: Light-mixing demo (CLSLab:Light) to perform color matching via RGB LEDs and a light sensor for under 100 USD and less than an hour of setup. Our tutorial covers ordering parts, verifying prerequisites, software setup, sensor mounting, testing, and an optimization algorithm comparison tutorial. We use secure IoT-style communication via MQTT, MicroPython firmware on a pre-soldered Pico W microcontroller, and the self-driving-lab-demo Python package. A video tutorial is available at https://youtu.be/D54yfxRSY6s. For complete details on the use and execution of this protocol, please refer to Baird et al. 1 . Competing Interests: Declaration of interests The authors have been exploring selling at-cost kits via a crowdfunding platform called GroupGets. As of April 23, 2023, the cost breakdown is as follows: List price: 80 USD + shipping (depends on location). GroupGets fee: 15.57 USD (10% + 2.9% + 5 USD). Hardware cost: 51.19 USD. Labor/testing: 20 min (est. 6 USD). Profit: 2.24 USD, offset somewhat by bulk pricing discounts. Note that this assumes purchasing a Pico W with presoldered headers. See round 1 and round 2 and a discussion of packaging open-source hardware as commercial kits. (Copyright © 2023 The Author(s). Published by Elsevier Inc. All rights reserved.)
