Keypad

Demonstration setup for keypad connected to NI myRIO MXP.
This project teaches students how to interpret data from the switch array that makes up a keypad. Students complete activities that demonstrate the use of pull-up and pull-down resistors, and how single and multi-key presses can be decoded using myRIO and LabVIEW. In these activities, students follow steps to demonstrate correct operation of the LED display, watch videos involving theory, and participate in a short activity after each video.
