### Measuring Battery Capacity with an Arduino - Denis Hennessy

I'm preparing for a little Arduino project that our teacher announced that will most likely be a discharge voltage measurement of a capacitor with some curve fitting in Excel. So my goal is get the . Measuring the capacity of a capacitor with arduino? In the Arduino, convert each reading to an ASCII number followed by a carriage return

### Measuring Voltage with Arduino - Starting Electronics

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).

### Battery Capacitance measurement with Arduino ~ Powertronics

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.

### HOW TO MAKE CAPACITOR METER - ARDUINO UNO - LCD

Capacitance measurement with the Arduino Uno. Posted on January 21, 2014 by jon. The only problem would be if someone hooked up a charged capacitor, but that could destroy the Arduino even if the I/O pins were set as inputs. I guess you could add an external resistor, but how big should that be? changing the IN_STRAY_CAP_TO_GND does not
