NOTE: This page references FED1.0, published by Nguyen et al: https://www.ncbi.nlm.nih.gov/pubmed/27060385

This page will remain up for historical reasons, but if you are new to FED we suggest you start with the new version, FED2. We have made several improvements that make it easier and cheaper to build. Instructions here: https://hackaday.io/project/72964-feeding-experimentation-device-fed-20. If you have any comments or questions, please send us an email. Thanks!

FED is open-source - we encourage you to fork, modify, and hack it to add new functionality. We'd also love to hear about it when you do, so please drop us a line!

  The latest Arduino sketch for running FED. We've recently added a new version to the Arduino code (FED_SD_VersionB) to account for Adafruit's newely released SD shield. In order to find out whether you have SD shield version A or B, please go to the following URL: https://learn.adafruit.com/adafruit-data-logger-shield/wiring-and-config

• Note: once coin battery is inserted into the SD shield, please don't remove it! This prevents Real Time Clock (RTC) errors.
