I have a 555 and a 4017. My question is that there seems to be a bunch of 7-segment LED controllers for BCD outputting decade counters but I don't see (or know what to Google) for a non-binary coded decimal output. The 4017 outputs single digital pulses on a given terminal which indicates which number the count is on. There are 10 pin outputs for values 0-9. The problem is how to take these outputs and control a 7-segment LED with them. I do not want to hand wire a bunch of connections to the LED if at all possible. Could you guys help with either the IC number that handles the 4017 to LED control or perhaps give a better solution than hand wiring the LED myself? Thanks. 4017 link: http://www.doctronics.co.uk/4017.htm#pins [Broken] 555 link: http://electroschematics.com/wp-content/uploads/2008/11/lm555.pdf Edit: If you guys look here: http://www.youtube.com/watch?feature=endscreen&v=2PBSOLG4n08&NR=1 you will see what I mean about the intermediate controller IC. The problem is that the IC this guy uses expects BCD inputs and the 4017, at least by default, doesn't code its output in binary.
