Small simple fish feeder
thingiverse
A fish tank feeder, ideal for goldfish, offers 4 or 8-day feeding duration. Powered by an Arduino and micro-servo, it utilizes a large IKEA straw as food containers. The provided ZIP file contains the Arduino code. Upon power on, the servo activates first before filling the containers with food. A 23-hour wait initiates the first feeding cycle, followed by 24 hours between subsequent feedings. Adjust the angle to release only one container at a time. Updates include fixing the last four moves' detachment issue and adding a straw-based food loader picture (June 6, 2015). Previous enhancements made it compatible with SG-90 servos, updated code for quiet operation and support of two feeders for up to 8 days of feeding (July 12, 2014).
