Digital Electronics:

Here is where we discuss the lifeblood of the digital world.. You'll see gates, flip-flops, inverters, and learn the meaning of AND, OR, NAND, NOR, XOR, NOT, and more.

Along the way, I'll put in learning projects. Just very simple ones to illustrate the action of the chip so you can actually see what they do instead of just reading about it.

So, we'll first build an oscillator that can pulse slowly enough for you to see the action which will probably be an LED attached to the inputs and outputs. We'll also put in a single step mode. I realize that some of you already have some equipment, so just skip over where you think it is appropriate.

Even though some things are more easily realized using microcontrollers, individual chips are still very useful for many things. And besides, you don't have to learn programming, buy a programmer, etc.

I made a very sophisticated proximity detector system using only Op Amps and a few digital chips. I'll put a write up in the Mixed Signal projects section, providing I can find the schematic. If not, I'll show you how to design a new one. It can be a lot of fun.

I buy most of my electronics parts from JAMECO Electronics   (I also buy from Digikey, and Mouser, but I don't have the links to paste in yet) Jameco is geographically close (a few hundred miles) and my UPS orders always arrive the next business day without having to pay for next-day service.

They ship the same day if you order before noon Pacific time. Click the picture below or the link above and it will open in a new window so you don't have to leave my site to buy your parts.

If you need ANY math help in general,Math Tutor is an excellent site! Even I've used a couple lessons as a review! (opens in a new window) He also has excellent tutorials for using specific calculators, many of which are used in college engineering programs. He even has one for my latest, the HP 50G.
