 ## Use cases  
 The cheap auto-feeder for my cats broke. It was a fancy plastic-thingy with voice-recording-function & programmable to feed several times a day after playing back your voice (cats don't give a sh$7 for your voice - they come when they hear the food falling into the bowl). It was never precise - a concern for the amount of nutrition it gave the cats. And it was not reliable, as the torque of the internal moving mechanism was insufficient to spin the separator/proportioning wheel through the food reliably. In addition, the batteries were always drained in a day meaning very grumpy cats when we returned!  
 
-Thus the wish to install a high-torque stepper-motor (with shifting gear) was born. I could power it with mains instead of relying on a battery, control it over WiFi from my smarthome automation hub. Tasmota now offers a way to do this!

 The **"TasmotaSmartCatFeeder"** circuit consists of a WeMos D1 mini, a A4988 controller, and two power supplies (5V&12V). This all fits into the housing of the feeder and costs less than 50€!
