| can create a simple circuit that shows varying brightness of
| the LED depending on how close you move your hand or an
| object to an antenna connected to one of the transistors

| or even a hint of a digital signal involved at all.

| One of the simplest examples is a voltage divider: if you put
| two resistors across a DC voltage source, like this:
| V+-[R1]-C/-[R2]-GND
|
| The voltage at the C/ point will be: V+ *
| (R2 / (R1 + R2))
|
| There are infinite possible values for that voltage,
| depending on the voltage source and the two resistors. It
| cannot necessarily be expressed exactly in a digital circuit,
| and it will fluctuate over time as the environment changes in
| temperature, humidity, EM noise, and so on.
|
| I usually recommend _The Art of Electronics_ as a well-
| written, beginner-friendly textbook which covers the basic
| concepts.

| Thanks for sharing! Does this teach one how to design circuits

| Also, someone suggested 'basic electronics: theory and

| compare?
