Demonstration setup for digital potentiometer connected to NI myRIO MXP.


Digital Potentiometer

This is lab 31 of 39 in the course
by Dr. Ed Doering | Rose-Hulman Institute of Technology
This project introduces students to the operation, interface theory, and features of a digital potentiometer and the SPI communication protocol. Students complete an activity to build an interface circuit, use LabVIEW and myRIO to set the virtual wiper position, and observe the resulting change in resistance. Through these activities, students follow steps to demonstrate correct operation of the digital potentiometer, watch videos involving theory, and participate in a short activity after each video.
