Feeding cat with obniz
Things used in this project
- Obniz
- Battery or USB adaptor & cable
- Screw and pipe
- Servo motor ( unlimited rotation)
- Pet food — as much as possible
Step 1 — setting up obniz
You just need to follow three steps to set up your obniz.
- Connect obniz to wifi
- Connect devices like LED or motors to obniz
- Scan QR code of obniz and start programming. You do not need to install any software.
Step 2
Cut pipes and prepare the screw. I made the screw by using 3D printer. Then, connect screw to a motor and put them into a box.
Step 3
Now you need to connect the servo motor to obniz as below.
io0: GND,
io1: VCC,
io2: signal
And then power up your obniz.
Step 4
Write codes below and put food into the bottle. Food will come out from the pipe.
Feed your pet!
You just need to open HTML on your browser with your smartphone. Now you are ready to feed your pet from anywhere!

obniz.onconnect = async function () {var numberOfMeal = 0;var lastTimeMeal;$("#dispMeal").text("Number of feeding : "+numberOfMeal)var servo = obniz.wired("ServoMotor", {gnd:0, vcc:1, signal:2});
$("#meal").click(async function(){numberOfMeal++;lastTimeMeal = getTime();$("#dispMeal").text("Number of feeding : "+numberOfMeal+", The last time : "+lastTimeMeal)servo.angle(0.0);await obniz.wait(10000);servo.angle(6.9);})}
