LED effect on the KA4558 LF355 chip

hello everyone I want to introduce the LED flasher on the KA4558 and LF355 chip
for this we need a few resistors, a capacitor and a microcircuit

the circuit is simple and does not require adjustment; the only thing is not to confuse the pinout of microcircuits, or rather, operational amplifiers
here is the pinout of the KA4558 and LF355 chips
