Feeding cat remotely using smartphone

sa112

Do you wanna feed your pets from outdoor? I have made a feeding machine which can be controlled on the browser using smartphone.

 

 

What you need to prepare

  • Obniz
  • Battery or USB adaptor & cable
  • Screw and pipe
  • Servo motor ( unlimited rotation)
  • Pet food - as much as possible

 

Step 1

Cut pipes and prepare the screw. I made a screw by using 3D printer. Then, connect screw to a motor. and  put them into a box.

 

Step 2

Connect servo motor to obniz.

io0: GND,

io1: VCC,

io2: signal

 

Then power up your obniz.

Step 3

Write codes below and put food into the bottle. Food will come out from the pipe.
