what do the most popular integrated circuits do and what are some projects for them? Answered

I was wondering what some popular integrated circuits were (e.x. 555), what they do and what some projects you might be able to do with them, I would also like to see a "dumbed down" version of a schematic so it is easier to understand.

There are literally millions of different types of ICs. There are audio ICs, logic ICs, RF ICs, memory ICs... There is usually an IC for each purpose - for example, the LM386 is a simple audio amplifier chip used for battery-powered amplifiers that can drive a small loudspeaker. I've seen them used in cordless phones, cheap radios, intercoms and other places! Another example is the TL071 - an "operational amplifier" that can drive high impedance headphones, can be used as a low-noise microphone amplifier, used as the amplifier in a guitar "fuzz box", or used as part of an analogue computer... A quick look around the 'net will show you lots of IC circuits - some simple, and some really complicated. Choose your electronic application (a radio, an amplifier, a light sensor or whatever) and type it into Google - try "IC loudspeaker amplifier schematic", and you'll get hundreds of hits! You really don't want "dumbed-down" electronic designs. You'll have to make a little effort to learn about the principles of electronics, but it's not hard!

The most popular integrated circuits are the 555 timer chips.
  • They are used to make LED's flash.
  • They are used to make a tone on speakers.
  • They are used as a signal generator to test electronic equipment.
And they have a lot more great uses.

here is a schematic of the simple LED flasher below from this site.
