TY - JOUR TT - A TURBIDIMETER DESIGN EXPERIMENT FOR BIOMEDICAL ENGINEERING UNDERGRADUATES AU - Kurt, Dilan İlke AU - Yuksekkaya, Mehmet PY - 2017 DA - August JF - The Eurasia Proceedings of Educational and Social Sciences JO - EPESS PB - ISRES Publishing WT - DergiPark SN - 2587-1730 SP - 121 EP - 127 VL - 6 KW - Turbidimeter KW - transistor KW - microcontroller KW - laboratory experiment N2 - Thisarticle describes a laboratory experiment to teach phototransistor and LEDdriver circuits and analog to digital conversion using a microcontrollerthrough a turbidimeter design for biomedical engineering undergraduates.Teaching electrical circuits and concepts using a real design helps students touse the theoretical knowledge practically and apply it. This type of realapplication motivates students. The purpose of this design is to drive an LEDby BJT transistor and to get a voltage value related to the absorbed light fromthe LED by phototransistor and to convert the voltage signal of the absorbedlight into digital by using microcontroller. The test of turbidimeter in theexperiment is applied by measuring the added soil to water in cuvettes. In thispaper, similar experiments are reviewed, the experimental procedures areexplained, the methods for evaluation the success of the experiment are determined.As a further work experiment will be applied to biomedical engineeringundergraduates and evaluation of their success and motivation will bereviewed.   CR - Chen, H.
