Dog Food/Water Feeder (RustyBot1.0)

This project was done to automate my everyday task of feeding the dog (twice a day). The feeder is set to a routine schedule of feeding the dog once in the morning and once in the evening. The machine can be halted or forced to feed him at my command. Fresh water is dispensed prior to each feeding and goes through a cleaning cycle at night where it is drained at night to prevent scum build up in the bowl. After feeding it will email me the time he received his last meal and how much food was dispensed.
