[Re-curation] Voltage measurement with the Arduino board: Logging data

Project description

John Errington's Experiments with an Arduino Voltage measurement with the Arduino board: Logging data Having taken the required measurements we can now save data to a file on an SD card. For this project I am using a MEGA because the UNO has too little storage for global variables. There are two main hardware options; An arduino shield, as shown here, which makes all the connections for you, and supports an ethernet port as well as the sd card. This allows readings to be continuously displayed in the form of a web page, as described below. This shows an SD card interface which connects to…
