[SeanHodgins] has a project in mind where he needs to sample over 500 analog sensors. To get ready, he made a breakout board for 32-channel analog multiplexer device he wants to use. He put the ...

There was a time when building electronics and building software were two distinct activities. These days, almost any significant electronic project will use a CPU somewhere, or — at least — could.

Few IC-schematic symbols are simpler than the one that depicts an analog switch (Figure 1a). A basic switch comprises just an input, an output, a control pin, and a couple of power-supply pins. Yet, ...

There are different methods to measure current. One method is to use a resistor across a current output and measure the voltage. The voltage across the resistor is measured using ohm's law: where I is ...
