hef4794 to 74HC595

I used this to verify my 74HC595 circuit is working.

Then I tried my hef4794 programs and they work if you change the pin designators or you could just change the wiring. This will leave some unused code but it doesn’t hurt a thing.

//Pin connected to ST_CP of 74HC595
int latchPin = 8;
//Pin connected to SH_CP of 74HC595
int clockPin = 12;
////Pin connected to DS of 74HC595
int dataPin = 11;


My code is here for the knight rider one. As always the pathetic +5volt signal can control anything given the proper interface.

My next foray will be to install a temp sensor and have it read out on the LEDs
