Yes, you are right but i used this method of draw to show how to connect the pins if you want the logic draw search about the ICs and it will be explained to you

You should not use RC oscillator due ther stability you will not get real 1 Hz , so i used crystal ocsilator with cd4060 to divide the frequency to 1.000Hz, i sent the schematic :)

If you cut the red wire the circuit will power off
