[Erik Berglund] used [coberdas]’s fish feeder as the bottom, upgrading it with a greater servo, including a Raspberry Pi Zero W together with software program for the Pi and an Android software to manage the schedule of feedings. There’s additionally a DS1307 actual time clock module to maintain precision time and a push button for “manual” feeding. If you’re trying to comply with alongside at residence, yow will discover the Python scripts that run on the Pi and the supply code for the Android software of their respective GitHub repositories.
