A potential divider, also known as a voltage divider, is a simple yet essential circuit used to reduce voltage to a desired level. It consists of two resistors connected in series close seriesA way of ...

Here is a useful circuit for Arduino lovers and experimenters. It is a simple digital voltmeter, which can safely measure input dc voltages in 0 to 30V range. The Arduino board can be powered from a ...

Applications sometimes require the generation of a voltage that is below the reference rail. Many design engineers would just use a second regulator to generate this voltage. However, a simple change ...

I figure this fits into "Other Hardware." I have a little battery powered fan I'd like to use more, and I'd like to use with rechargeable (NiMH) batteries, but because these are just stupid fans ...
