Hi.
As a victim of a secondary school education, I have been 'brought up' using 4000B series ICs. However, I look in this forum, and on web sites, and they all seem to use some form of 74... series ICs. Then they have all sorts of problems because you need to provide an approx 5v supply, meaning that you can't use a normal 9v battery (which is the simplest for testing projects).
I can't understand why people make it so difficult for them selves. Am I missing something?
Thanks :?
