ECT 274 Week 3 iLab Binary Modulus Counters NEW

I.OBJECTIVES

In this lab, you will create a binary MOD-10 up-counter ARM project.
II.DESCRIPTION

A MOD-10 counter has 10 states. For this lab, the count sequence will start at state zero and count to state nine. The count sequence will be displayed on the LEDs and on the OLED display. The VI utilizes the ReadWriteIOBoard SubVI located in the C:\DEVRY\IOBOARD folder to output the binary number to the LEDs.
