Feed The Dog

Inspiration

Not having to worry about coming home to feed our dog.

What it does

Automatically dispenses food and water for the dog based on sensor readings. Will be connected to an app in the future so you can choose when to feed the dog.

How we built it

Hooked up an Arduino Uno to a force sensor and a water level sensor. If the water and food levels are low, dispense food if it’s been 6 hours since the last meal and constantly dispense water.

Challenges we ran into

The DC motor can’t be controlled by the Arduino so we needed to make a servo push a button. We didn’t have a transistor. This was the only way we could turn on the motor. We also were not able to hook the Arduino to WIFI because we were using an ESP 8266 shield. We were going to use the Blynk app to control the project over WIFI but the ESP wasn’t able to pass the information correctly.

Accomplishments that we're proud of

We created what we wanted. An automated food and water dispenser.

What we learned

Problem solving. Building circuits for the hardware. Learning how to connect hardware over WIFI.

What's next for Feed The Dog

Connect the project to WIFI.
