Pet feeder +1172624A

Overview

Tuya Lichuang’s pet feeder activity

A cardboard box was used to make the outer shell. Since there was an electric push rod readily available, I used it. Later I found that the push rod had a short stroke and a slow speed, but I made do with it. The push rod rises to push the grain to the exit and slide down, thereby realizing feeding.

Using Arduino as the MCU end, I didn't have time to learn PCB production, so I first used a perforated board to weld an adapter board and connected it to a motor drive expansion board.

The overall effect after combination is to have only two functions: night light and feeding:

Scattered points: By the way, I would like to ask if WinCE5.0 is going to be eliminated. Should I still learn WinCE6.0 7.0 8.0 or something like that?
Scattered points: Let’s discuss whether WinCE5.0 is going to be eliminated, and whether programmers who are proficient in WinCE5.0 need to learn WinCE6.0 7.0 8.0 or something like that?
