Larson_Scanner
A simple Larson Scanner based on 74HC595 Shift Register
Hardware
An Arduino UNO is used to interface the 74HC595 shift register which sequentially lights up the LEDs connected to output pins QA - QH
Circuit Diagram/Schematic
Software
A user-defined function shiftWrite is used to write to the internal register of shift register sequentially from QA to QH on the rising-edge of clock and then latch it to the output on the falling edge of the clock.
