Hi,
I have a simple for you guys question. Take a look at this:
http://examples.oreilly.com/9780596153755-files/mkel_04/mkel_04_035.pdf
IC3 is a 4026 (CMOS decimal counter) and IC4 is a common cathode 7-segment digit display (a package of 3 by Kingsbright).
The output from the 4026 enough to drive the digit segments but could be brighter. The author suggests a transistor.
The question I have is basically where each leg of the transistor would go. I understand that the output of the 4026 would go to the base, but I can't figure out where to connect the collector and the emitter, since the load, in this case is 1 pin of the display. I know it's obvious to you, but I can't figure it out.
For example, pin 13 of IC3 goes to pin 4 of IC4. How do I connect a transistor between those two?
Thanks!
