I'm new to electronics, i know only what i've read online.
I built the attached circuit, with a few changes.

(scroll to the bottom of linked page)
I Changed the 555 to monostable, & added a push switch.
When power is applied the counter
boots up on the digit "9" instead of "0", which is undesirable.
The state is set by the 4 outputs of the 4029.
The 4029 can be reset by briefly setting the preset pin "1" high.
how could i achieve this on power up.
Also i've been studying the truth table for the 4511.
Is there any danger in me using its inputs (eg.
0 1 0 0 which drives the counter to the digit "4")
to enter into a logic switching circuit. (NOR & AND Gates)
And do any components need to be connected between them.
Thanks
