Update: this project is also on Hackaday.io: https://hackaday.io/project/21409-arduino-datalogger-with-microsd-card
Hey everyone, how are you doing? Today's video is all about a project I have been thinkering around (and designing) for a long time: an Arduino-based data logging system. It basically reads data from Arduino micro's analog and digital inputs and saves it to a microSD card.
The reason I created it is that I need a datalogger myself; I am always experimenting with analog and digital data from physical systems (rc cars, servo motors, etc etc) and I simply love to record said data for after-the-fact analysis and comparison.
I have programmed it to read all four analog inputs of Arduino micro (A1..A4) and store the data in '.csv' format inside the microSD card; it allows me to easily post-process and copy/paste/move information.
The schematic diagram (made in Fritzing) for the datalogger is seen below, and the Arduino code can be downloaded in this link (or copyied from below as well - use it without worries).
