I'm working on arduino and 74HC595 Shift Register, I attached the LED on output pins. I was doing base on this tutorial: http://arduino.cc/en/Tutorial/ShiftOut.
It's run well but when I reset/restart the arduino all of the outputs on the 74HC595 turn off. In my case, I want to keep save the output on 74HC595 when the arduino reset/restart. Is possible to do that? could anybody give solutions of this problem?
