A while back, [Kutluhan Aktar] was trying to hack their chickens, quails, and ducks for higher egg production and faster hatching times by using a bit of classical conditioning. That is, feeding them at the same time every day while simultaneously exposing them to sound and light. Once [Kutluhan] slipped enough times, they hatched a plan to build an automatic feeder.
This fun rooster-shaped bird feeder runs on an Arduino Nano and gets its time, date, and temperature info from a DS3231 RTC. All [Kutluhan] has to do is set the daily feeding time. When it comes, a pair of servos and a pan-tilt kit work together to invert a Pringles can filled with food pellets. A piezo buzzer and a green LED provide the sound and light to help with conditioning. Scratch your way past the break to see it in action.
If [Kutluhan] gets tired of watching the birds eat at the same time every day, perhaps a trash-for-treats training program could be next on the list.
