Connect your Arduino over USB. Select the appropriate port and board. Start the Arduino IDE's Serial Monitor. Set the monitor to 115200 baud. Observe as the meter zeroes itself. My unloaded capacitance is usually about 50pF. Connect the capacitor to be measured as shown below. Observe as the meter converges on a capacitance value.

### How to Make an Arduino Capacitance Meter - Circuit Basics

Measuring DC Voltage using Arduino Created on: 23 May 2013 Arduino analog inputs can be used to measure DC voltage between 0 and 5V (on 5V Arduinos such as the Arduino Uno when using the standard 5V analog reference voltage).

## Arduino capacitance meter - Make ### Battery Capacitance measurement with Arduino ~ Powertronics

Logging small capacitance. The accuracy of the measurement in this case would be entirely up to the design (circuit topology and component selection) of the external circuit. Each capacitance meter has an RC circuit with known resistor values and an unknown capacitor value. The Arduino will measure the voltage at the capacitor and ### Measuring Battery Capacity with an Arduino - Denis Hennessy

Capacity is the leading health indicator of a battery, but estimating it on the fly is complex. The traditional charge/discharge/charge cycle is still the most dependable method to measure battery capacity. While portable batteries can be cycled relatively quickly, a full cycle on large lead acid batteries is not practical for capacity measurement. ### Measuring the capacity of a capacitor with arduino

This Simple capacitance measurement circuit using IC-555, is used for the frequency counter as digit number display, that can measure the period. To show a capacitance value of the capacitor directly. According to the circuit shown in Figure 1. Shows the using IC 555 as the astable multivibrator. The period is as follows. T = 0. 7 (RA +2 RB) Cx. ### Arduino Playground - CapacitiveSensor
