DIY Arduino Capacitor Tester
In this video we make an Arduino capacitor tester.We use two digital pins, one for charging and one for discharging the capacitor. One analog pin as our voltmeter input, and a little add on circuit with a couple of resistors.
This works on the principle of TC=R*C. We know R (in this case 100kOhms) and we measure TC until the cap reaches 63%. When that happens we can calculate C.
