Davide GombaJanuary 16th, 2012

[Carlo Denaro] is sharing a smart solution to save digital pins while controlling an LCD, using Shift Register 74HC595. A simple yet useful project with skecth&libraries, datasheets and Fritzing schematics.

    I always used 595 to work with lot of leds, leds matrix and LCD! It’s like extending Arduino with more and more pins! 🙂

    I already though of doing this with an i2c MCP23008 like I saw in the playground but with an 595 is much nicer and simpler, also it comes with a Arduino library for it. Thank you, Carlo 🙂

    Its also possible with only 2 pins:

    Is it ok to use a 74LS595 IC rather than 74HC595 is it ok?
