I'm in an freshman level EE class at the moment (circuit analysis to be exact), and we have to build a circuit of our choice from any schematic we can find (as long as it has a practical use, and not too simple like a 555 flasher).
I found this schematic on Jameco,
http://www.jameco.com/Jameco/Products/ProdDS/2169580Schematic.pdf
I understand everything on this schematic except pins 3 and 4 on the 4017 chip. It shows a path going through this chip, and then those pins are highlighted in green but don't appear to be going anywhere, not even to ground.
Can someone explain to me what this implies?
