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 simple-ish device takes a voltage reading at Arduino pin A0, and logs it to EEPROM with a timestamp from a DS3231 RTC module. When you press the button, all stored data will be written to UART at ...

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 ...

With the AD converter of the Arduino UNO you can measure voltages. How can we improve the accuracy of the results and what about noise and interference?

Build Your Own Arduino Voltmeter Circuit and Voltage Divider Which Can Measure Voltages From 0V to 30V, Including 12V. Visit To learn More.

The circuit was based on the use of Arduino AVR to build a high voltage programmer which can be used to fix pesky fuses. The circuit was based on the use of Arduino AVR to build a high voltage ...

Here is the Arduino Data Logger Project covered with circuit diagram and code to learn how we can log temperature and humidity to SD card at a specific interval of time.

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 ...
