i am using HD74LS164 for one of my projects.i activated the IC by give 5v to pi14 and grounding pin7.then i connected pin 13 to pin1 and shorted pins1&2 when i switched on the power supply all the LEDs i connected to the outputs switched on and when i gave 0 to pin 1 and when the clock went low all yhe LED's went low.can anyone tell me the problem?

if possible give me a complete circuit to switch on the LED's one by one in a loop.
thank you.

Ur circuit is wrong, try the attached diagram for a change
Clock is at 1 kHz.
when u trigger the leds will light one by one and when u off the trigger the leds will turn off one by one
The LED resistors are 220Ω 0.5W
