hi i could do with just any general info on how a 555 monostable into 4017b circuit works, or uses of this circuit and the positive points and negative points
Thanks

No, do your own research on the web then do your own homework.
thanks alot mate
done my own reasearch but i thought you could help more but maybe i was wrong
Lots of 555 & 4017 info on the net.
Thanks alot mate
Not so long ago people used to have to buy books or go to libraries to get the information
they needed. Now the world wide web is at our fingertips but for many it doesn't seem good enough.
What were you hoping for? Something ready to submit to your teacher?Originally Posted by minifletch
hense why im using this website to try and find information out via the internet
no i was after some information like the circuit idea you showed me that i could see how it worked or just some possible uses for it
Google "555 CD4017" should show thousands of hits. 555 is a timer, 4017 a Johnson counter.
sorry if my reply to your info came accross as being sarcastic, it wasn't meant to be i was genrally greatful for you're help
This site has info and projects using the 555 and 4017.
555 and 556 Timer Circuits
4000 series CMOS Logic ICs
Sorry for what seems to be a basic question...
In many of these 4017 circuits (like Bill's in post #4), one of the outputs is connected to a Darlington pair (TIP 120) through a 10 K resistor, while many other times no resistor is used to go directly into a transistor. The 4017 outputs only seem to deliver about 10ma, so how should the resistor value calculated?
You wouldn't need it if it only going to put out 10mA some chip are made to drive a transistor from the output. The output is limited in the chip.
