He further explains that, with the Arduino Uno, you can remove the reference capacitor from the circuit, and simply use the stray capacitance present in the board and microcontroller, which can be ...

On one range, the Arduino charges the capacitor through one resistor and discharges it through another while timing the operation. The amount of time taken corresponds to the capacitance.

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 ...

Capacitive-Water-Level-Sensor- A simple and cost-effective capacitive water level sensor using an Arduino. This project measures the water level in a container by detecting changes in capacitance ...

The EasyTouch capacitive touch sensor can be used with either the Arduino platform or the Raspberry Pi mini PC using the EasyPlug breakout board if required. Watch the video after the jump to ...
