This is an automatic feeding machine, to feed my pet when I am away on vacations.
- 2 programmable alarms, that trigger the feeding actuators.
- Worm gear driven by DC motor to feed the food.
- Output to connect to 12V water valve (for water also).
- Food blockage on feeder detection and release routine (protect DC motor + components).
- Safety error blocking (avoid feeder constantly blocking).
2 Electronics Development
The electronic unit is composed by an Arduino Nano, an RTC module, an ACS712 current sensor, an L298 motor driver, and an LCD screen.
The first development sample was created using perf board and had a considerable size. Then, the second sample was developed.
3 Feeder Development
The feeder system designed was based on a worm gear driven by a DC motor. The first prototype was designed and put to testing. During the initial tests, it showed to be too small for the food size that my dog eats. So a second version of the prototype was made.
