textbook 555 astable at what seems to be 15 hz. No need to on/off the switch.
Sa multisim, try to change the max time and step time and always clear intrument data before simulating. Baka dun lang.
Sa bread board, try separating the 555 timer circuit and verify if it outputs the desired square wave with an oscilloscope.
tapos manually trigger the counting sa 4017. Divide and conquer hehehe.
Hope this helps.
