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 ...

Have you ever found the need to measure the capacitance of a capacitor? No multimeter handy (for shame)? Well, as it turns out you can actually measure capacitance using your Arduino Uno, with no ...

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 ...

// This is typically around 24.48 pF, but varies slightly from board to board. const float IN_STRAY_CAP_TO_GND = 24.48; // When we analogRead, the internal sample-and-hold capacitor connects to A0. // ...
