Each Arduino capacitance test relies on a property of resistor capacitor (RC) circuits- the time constant. The time constant of an RC circuit is defined as the time it takes for the voltage across the ...

A capacitance meter is a device that is used to measure capacitance of a capacitor. In this project, we will develop two circuits: a) CIRCUIT1 - to measure capacitance in the range of 1µF to 4700µF b) ...

If you are just starting out in electronics, you need tools. But it is hard to build all your tools. Even though we see a lot of soldering station builds, you really ought to have a soldering iron to ...

[Marcus] has written up his experiences using the AD7746 capacitance sensor. He used the SparkFun breakout board in conjunction with an Arduino. The available Arduino code wasn’t that great so he ...
