Electronic Circuits for the Evil Genius Second Edition 64 Lessons with Projects

  • HAVE YOU SEENTHE WIZARD OFOZ? Don’t befrightened, and don’t “ignore the man behind thecurtain.” Any technology that one does notunderstand is often interpreted as “magic!”Knowledge, Design, ControlAs you start to learn how to control digital inputs,you actually start to understand how some of the“whiz-bang” electronics around you actually work.Go out and buy a copy of a monthly electronicsmagazine. You will actually understand more thanyou expect. Remember, electronics is not hard—just lots of new information.Lesson 26Building the NAND Gate OscillatorHere, just like the title says, you will incorporatethe two unused NAND gates of the 4011 and buildan extension onto your existing circuit. Thatextension will create a flashing output.Add to your breadboarded circuit. Don’t stripyour breadboard.Here you will get some dramatic changes byadding three basic components and changing somewiring to use the other two NAND gates.Note what is needed in Figure L26-1 and theParts Bin.The NAND Gate OscillatorSECTION 899RC1 and RC2 are highlighted.Figure L26-1
