This is an automatic pet feeder, I use it to feed my budgies when I'm on a trip. It can only be used with small seeds like millet as larger seed/food can get stuck in the funnel.
Parts required:
Mechanical
2 x M3 screw and nut
Some 550 (ϕ4mm) 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
