The ability to change resistance ... stretch sensors. Potentiometers, or pots, are basically voltage dividers: a method of dividing a given voltage down to a lower level. As the schematic shows ...

In previous articles I talked about fixed value resistors as well as variable ... resistance would increase in the desired gradual manner, reducing the current through the coil until the circuit ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

Often, it's necessary for a sensor system to compute the ratio of two capacitors. Doing so re-duces the transducer's sensitivity to dielectric errors from such factors as temperature. Furthermore ...
