AC Capacitance and Capacitive Reactance
https://www.electronics-lab.com/article/ac-capacitance-capacitive-reactance/
Introduction Such as for inductors, the electrical behavior of capacitors also depends on the nature of the source : DC or AC. We will see through this tutorial that in some way, the capacitor can be seen as the opposite of an inductor in terms of frequency functioning. Like for the resistors and inductors, we […]
Arduino Capacitance Meter Using TM1637
https://www.electronics-lab.com/arduino-capacitance-meter-using-tm1637/
In this instructable by gustavio101 you will know how to make a capacitance meter using Arduino displayed on the TM1637 display with a range from 1 uF to 2000 uF. To build this project you need the following parts: Resistors 1x: 220 Ohm 1x: 10 kOhm, 8000 Ohms also would work depending on your code […]

by braulio777 @ instructables.com This project lets you measure capacitors in an alone range of measure from 0.000pF to 1000uF. That is, a 16×2 LCD Display will be displaying a sole scale from 0.000pF to 1000uF whose main components will be an Arduino Uno and a 16X2 LCD Display. Arduino Digital Capacitance Meter – [Link]

electro-labs.com published another great project based on Atmega328P: We are building another opensource SoloPCB project which is very enjoyable to build and use. In our electronics works, we frequently need to know the actual value of a capacitor. As you know, small sized SMD capacitors have no markings showing their values. Or there are lots of […]
Compensation of Oscilloscope Probes

by Maurizio @ dev.emcelettronica.com: Using simple wires to measure signals with the oscilloscope would result in unreadable plots on the scope, the main reason being the noise coupled onto the “probe” itself. The first line of defense against that would be to use a coaxial cable as a probe, which would prevent external noise coupling. An unwanted […]
Capacitance Meter

by ThomasVDD @ instructables.com: Capacitors are vital components in electronics, but sometimes they are broken, or the value printed on the cap has become unreadable. Because my multi-meter does not have a capacitance measurement, I decided to make one! The principle of measuring capacitance is quite simple. The voltage of a capacitor charging through a resistor […]
