A data logger built on using the adafruit Datalogging Arduino Shield on an Arduino Mega 2560 R3. 3 types of different units can be measured right now: Current, Voltage, Temperature.

This project uses an Arduino UNO and a datalogger shield (like the one found here) to record voltage readings via ADC and save them in a .csv file on a SD card. The data logger also records the date ...

This won’t work correctly, though: the microcontroller on the watch is very good at getting the power it needs from anywhere, and connecting it directly to an Arduino would skew the results.

The Mayfly Data logger is a fully programmable microprocessor board which is fully compatible with the Arduino IDE and is equipped with a Atmega 1284p processor supported by 128K flash memory and ...

This project is a great example. [Scott Daniels] takes a look at the other voltage measurement options available to AVR chips used by Arduino.

If you use the analog inputs of your favorite microcontrollers, sooner or later you have needed to check their linearity and accuracy over the entire range of input values. This precise and compact ...

The extendable Arduino GPS data logger consists of a shield that is fitted with the GPS receiver, SD card reader, and accelerometer, together with an Arduino UNO board. This combination of ...

In many areas of science, Arduino based data loggers have become common enabling instruments because of their low cost and ease of use. However, battery life is commonly the limiting factor - ...
