AquaFeeder 2.0 Design

A simple diagram I made before setting out to create AF2.0. Will help you understand the design and function of the stand.

Circuit without LCD.

Complete circuit.

The fritzing diagram shows the entire circuit, along with the LCD and the servo motors.

I like electronics, Arduino in particular. I suck at programming (but i still try my luck at it). Other interests include music, particularly prog.
