This works really well. My multimeter only does capacitors up to 1000uf and only displays OL when it test bad, where this will give you an actual value for a dead cap. Thanks!
thanks man, I'm building a Tesla coil and am makeing my own caps but I dont have a lcr meter or a scope and my multimeter doesn't mesure capacitance, this should be perfect and I will build it first thing tomorrow morning. Great video, and thanks again *clicks subscribe button*
***** It gives you the capacitance of a capacitor (In microfarads) which is essentially how much it can hold, being that capacitance is coulombs divided by voltage, and coulombs are a measure of electrical charge. Therefore a higher capacitance would lead to a higher electrical charge which can be visualized as more water if you use a water and tank analogy. If you need calculate the percent to which a capacitor is charged, you can take the voltage of the capacitor divided by the charging voltage but just remember that capacitors do not charge linearly and the rate at which they do charge is dependent on the capacitance of the capacitor.
Hello or you can adjust the meter to measure large capacity such as supercapacitors ??? capacity in Farads !! ???? if you can help create such a gauge? Regards Tomek from Poland :-)
Thanks for uploading very useful demonstration ... can this capacitance meter measure capacitance in pF range..and, what is lowest capacitance range that could be measured using Arduno?
You do realize ALL electronic components have some percentage tolerance on the nominal value? Meaning a 10 nF capacitor can be 11 nF or 9 nF or some other value within its specced tolerance. Besides that nice video. Thanks!
Thank you. Please re-record keeping in mind (1) audio levels must be much higher (compare with music and switch back and forth) and (2) change blocking (movement) so hands and arms don't block (3) object is in field of view, and (4) don't jump sequences (e.g. A to B C to B, C to D, E to D is bad. A to B to C to D is good.), and don't use numbers we much keep in memory without knowing what it is (e.g. .000,000,000........................ microfarads (not nano so where am I?), and showwing chart without us knowing what part to look at leaves us starting ignorant and when we are told what to focus on, find it, we have to go back, all the while keeping info in memory. All this is to motivate you to delete this videw, re-record it, and post the corrected. Note other comments and incorporate them too. .
When you say that "meter is accurate", that is not quite correct. This is NOT about METER's accuracy. Fact: electrolitic capacitors are: 1) never have same value as printed on the face of them. They have +/- some percent deviation. This is inherent to the capacitors. 2) as electrolytic capacitors age, they leak and their values decrease. So, METER has nothing to do with any "accuracies" or "inacuracies". Meter is excellent. In order to test the Meter itself, you would have to compare this meter's reading with some known capacitor's value, for example by measuring capacitor's value with several other meters.
This would be a nice video - if you have tried not to swallow the microphone. This thing belongs outside your mouth! ;-) Anyway, you'll get a thumbs up :)

Thanks for the great video. Ignore the negative complaints. I have subscribed.

Nice project
Did it work for atmega328p ic
Who came up with the last one? Making use of internal resistors is a fascinating idea.
It's so accurate because it doesn't depend on adc speed.
Is it able to measuring 1 pf to 1uf range ??
You only need 2 wires to find out.
Hy, what type of resistors did you used when you made the circuit on breadboard (the one with the LCD)? Great job, 10x!!!

cant get third one to work, it does nothing, no display
nice, can it read capacitance more fast?
What frequency it is measuring the capacitance at?
im using an arduino leonardo, its not working correctly, why might that be?
where is the ino skech
where could i get the commented code of capacitance meter number 3? could you email me or something? im in desperate need of it. thanks a lot.
isn't necessary the lcd screen? i don't have one,
No you can just use the serial monitor
will this work for inductance as well ?
I would use a similar principal regarding the usage of the time constant. In this case using the formula for inductance instead
