When we teach this topic to 14- to 16-year-old students, they do not usually notice we use maximum light quantities of red (R), green (G), and blue (B) to obtain yellow, magenta, and cyan colors in order to build the well-known additive color diagram of Fig. 1. But how about using different light intensities for R, G, and B? What colors do we get? This problem of color mixing has been intensively discussed for decades by several authors, as pointed out by Ruiz's \u201cColor Addition and Subtraction Apps\u201d work and the references included therein. An early LED demonstrator for additive color mixing dates back to 1985, and apps to illustrate color mixing are available online. In this work, we describe an experimental setup making use of a microcontroller device: the Arduino Uno. This setup is designed as a game in order to improve students' understanding of color mixing.<\/jats:p>","DOI":"10.1119\/1.4944370","type":"journal-article","created":{"date-parts":[[2016,3,15]],"date-time":"2016-03-15T17:00:59Z","timestamp":1458061259000},"page":"244-245","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":20,"title":["A Simple Experimental Setup for Teaching Additive Colors with Arduino"],"prefix":"10.1119","volume":"54","author":[{"given":"Paulo Sime\u00e3o","family":"Carvalho","sequence":"first","affiliation":[{"name":"University of Porto Department of Physics and Astronomy, IFIMUP, Faculty of Sciences, , Portugal"}]},{"given":"Marcelo","family":"Hahn","sequence":"additional","affiliation":[{"name":"University of Porto Department of Physics and Astronomy, IFIMUP, Faculty of Sciences, , Portugal"}]}],"member":"3","reference":[{"key":"2023062923472220500_c1","doi-asserted-by":"publisher","first-page":"423","DOI":"10.1119\/1.4931012","article-title":"Color addition and subtraction apps","volume":"53","year":"2015","journal-title":"Phys.
