In the video, it looks like there are only three blue wires connected from the left 74LS173, but in the schematic, there are four connections from each 74LS173 to the 74LS245.
Am I correct that there should be four connections from the left 74LS173 and four from the right one, for a total of eight connections to the 74LS245?
edit) This is an instruction register.

I'm building a register using an SN74LS245N, and I'm having an issue where the LEDs D10–D17 are flickering even though they shouldn't be.
It seems like the LEDs flicker faster when I increase the clock speed.
I searched around for possible solutions and tried adding current-limiting resistors to the LEDs (420 Ω), but the problem remains exactly the same.
What could be causing this, and how can I fix it?

I searched more about this after uploading this post.
And now I think this happens because of floating inputs maybe?
I made this by following a video tutorial and connected it using a 5V 2A adapter, but the LED either doesn't blink at all or only blinks about once every 15 seconds. What could be the problem?
