Automatic Bird Feeder
thingiverse
This is a clever automatic pet feeder that I use to feed my parakeets whenever I'm away on a trip. It can only be used with small seeds like millet because larger seed or food can easily get stuck in the funnel. Parts needed: Mechanical 2 x M3 screw and nut Some 550 (4mm) paracord 1 x MG996R servo motor Electronic 1 x Arduino Uno micro-controller board 2 x 220Ω resistor 1 x 1602 LCD module 1 x DS3231 RTC module 1 x 4*4 keypad 1 x push button or switch Bread board and some jumper wire The Arduino circuit diagram is located at https://circuitdigest.com/sites/default/files/circuitdiagram_mic/Automatic-Pet-Feeder-circuit-diagram-using-Arduino.png. My Arduino code can be found at https://pastebin.com/N7fmDQ9d. A video showing the feeder in action is available at https://youtu.be/AG2FPEU-Gfs.
