STP16C596 Shift Register

This tutorial will show how to control multiple LED outputs from a microcontroller using an STP16C596 shift register. The STP16C596 is similar to the popular 74HC595 shift register, but it’s nicer because it can sink a constant current to the LEDs it’s driving. It works slightly differently, however, so this code won’t work exactly for the ‘595.

This is a stub. More explanation will follow, but for now, here are schematics and code for Arduino.

Parts you’ll need:

  • STP16C596 shift register
  • Arduino microcontroller
  • LEDs
  • 1-kilohm resistor
