Ardruino shift registers (74HC595)


This guide shows how to get outputs with 74HC595 and a Ardruino pro mini - Here only used as output !!


starting with 1 shift register, then 2.. Later you can daisy-chain the shiftregisters to get unlimmit number of outputs !
Depending on the speed you what to change the outputs with.

The shiftregister is

NOTE:
// const int ShiftPWM_dataPin = 11; // Orange
// const int ShiftPWM_clockPin = 13; // Green
// const int ShiftPWM_latchPin=8; // Brown
// MISO pin(do NOT use!) = 12; // Do not use the MISO pin for anything, because this interferes with SPI operation!
