Ok. I got monostable mode. I am pressing my little button and timer starts rolling. I getting HIGH on output 3 and it last some time. I wonder why how to connect it with some other circut to start rolling just after state from pin 3 will go back to LOW?
I am new in electronic so any help is very welcome. Thank you very much for help.

The datasheet for the TI NE555 gives this for a sequential timing circuit.
Have a look at the datasheet for the output waveforms and more details.
They've used a cap and resistor as a differentiator between the stages. If you've got an oscilloscope, it would be worth slapping it together on a
breadboard and looking at the waveforms. If not you could try a simulator.
One question you might ask yourself is, how is it safe to use the differentiator like that, given that it will produce a positive spike on the
other edge (that would take the TRIG input above the supply)?
