Shift Register


A hardware construction and software design project for students to illuminate eight LED's in varying patterns, using a PicAxe microprocessor and Texas Instruments shift register. An eight-bit byte is used as a sequence for lighting the LED’s. Several patterns of these sequences are programmed into the PicAxe 08M2. A momentary contact switch, via the interrupt command, is used to step through these patterns. A ten-turn potentiometer, via the readadc command, is used to vary the speed at which the shift register lights the LED's.
