Hi, I have read like every thread that mentions the HC595 serial in, parallel out shift register. I have checked my wiring 50 times. I have checked the data sheet countless times.
My problem is that it ways shifts in a HIGH whether the serial input is 0 or 5V. I measure on the 1st Shift register serial input pin (14), it is 0V. But then shifts high's in. I dont know what to do. I am so far behind on this project. Any help would be super appreciated.
I havent programmed code yet because I cannot get the logic right.At the moment I am testing it with debounced toggle switches (1K/10uF Low pass filter).
Is my schematic correct?
