This is an easy tutorial showing how you can control the brightness of an LED or ... value (its voltage on the adjustable pin, in this case it is connected as a voltage divider *see the schematic). Do ...

[Faransky] has created a very impressive Arduino function generator ... So [Faransky] uses a X9C104P 100KOhm 8-bit digital potentiometer as a voltage divider on the chip’s output.

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level ... This variable resistor is connected in a voltage divider configuration, and Arduino ...
