Photointerrupter

Demonstration circuit for photointerrupter, connected to NI myRIO NXP.
In this project, students will learn the principle operations of a photointerupter, the circuitry required for operation, and interfacing techniques to sense when the light path between the emitter and detector is blocked. Students complete activities to build the interface circuit, and use myRIO and LabVIEW to collect data and translate it into position and speed measurements. Through these activities, students will follow steps to demonstrate correct operation of the photointerruptor, watch videos involving theory, and participate in a short activity after each video.
