Another fairly good source of basic information is:
And also:
If your interests tend toward radio, TV, and other RF devices, here is = an=20 ancient favorite:
I found it most helpful to actually build and test circuits. There are = still=20 some kits and trainer modules that provide this, such as:
You can also learn a lot by developing and playing with circuits using=20 LTSpice, which is a free application with which you can make schematics = and=20 run simulations and see circuit performance graphically:
Another free simulator package is TINA, which you can get through=20
Here's a video:
It has user interactive components such as switches, pots, and LED = displays,=20 plus test instruments like scopes and multimeters. It also has a PCB = design=20 module.
The simulator approach is safer than building actual circuits, but it is =
sometimes more fun and memorable to build and test actual hardware. Just = be=20 careful with voltages about about 24V, and wear eye protection in case a =
capacitor explodes (which can happen even on low voltage battery = projects.
Have fun!
