DIY fish feeder (using towerproSG90 + arduinoUno)

Put together a fish tank auto feeder which works with a towerproSG servo.

Build completed with a Towerpro90 servo, Arduino Uno, an RTC, a push button, 10k ohm resistor, a breadboard (82mm x 53mm x 9mm), pin wires, TM1637 display.

Arduino code and schematic attached. Adjust code for feed timing, feed duration and quantity.

Printing:
Supports - not needed
Infill - 20%

Assembly:
a. Secure plates together with diameter 3mm self tap screws or equivalent.
b. Use a solder iron/ drill to create holes on the feeder drum depending on pellet sizes and feed quantity.
