Secondly, Yes, You said it I had your post in mind that’s why I specifically asked for this, and Yes, I have tried to couple the Latch pin with the Clock of 555 but I the LEDs start stuttering like instead of turning one LED on and move to next, sometimes it turns on 2 or 3 at a time and also turns them off all at once sometimes and kills the COOL effect that I want to achieve, but if I leave the Latch Hanging in the air, it smooths out the effect but sometimes goes crazy… (I know, I am an idiot and taking too much of all you good peoples time, but I really am invested in this and want to make it work)…
Yes, I also saw the diagram of the 595 and thought to myself that could work, but sadly, Putting the Pin 9 through an Inverter seems to do the trick… If I pass the Pin 9 directly to Data Line, nothing happens, it just stays either All LEDs on or All LEDs off…
Again, many many thanks for your time and effort…
Use the names from the datasheet, or the pin numbers. In both 74HC595 datasheets I looked at, there are no pins called Latch or Data. The inputs, from pins 10-14, are named nSRCLR, SRCLK, RCLK, nOE, and SER.
Also, fully specify the state of all the inputs when you report an experiment. Telling me you tied the latch and clock pins together (which are not the correct names) doesn’t tell me how the rest of the inputs were connected. It might be that when unconnected, noise at the RCLK pin is causing oscillation, so it’s continually seeing positive edges and loading the output latch. Things will stop if the noise quiets down, because there will be no more edges to clock the output latch.
It doesn’t make sense that looping QH’ back to SER wouldn’t work, but given that you’re new with this chip I don’t know if you’ve done it correctly. However, it’s hard to track polarity through the diagram in my datasheet since it’s full of redundant inverting dots. Like in the screenshot I posted above, why have adjacent dots on the output and input? That’s just noise.
If you don’t want to use an entire hex inverter chip for just a single NOT gate, you can use a 555. Leave COMP and Discharge disconnected, and connect both Trigger and Threshold to the input logic signal.
nOE input connected to GND.
SER connected to QH’
RCLK and SRCLK connected to the 555 output.
nSRCLR connected to the RC circuit.
