Well, I didn't include the circuit diagram and the libraries for the LCD and IC595. Basically I used a shifting register (IC595) to apply voltages to the pins of the LCD, and I wrote my own library for those.The connections aren't standard, however you can connect them anyway you want and write your own library.
Hey so I'm a little confused within the coding for this. These two libraries are included "../library/IC595.h", "../library/LCD.h" but I cannot find them online to import.Any help would be greatly appreciated.
Great guide, though, no need to use an arduino to generate PWM - I made do with a simple astable 555 based oscillator with fixed period and variable signal width (and of course inverting it throug an NPN transistor as it's more stable near the high end)
