akhlaque:
Very thanks to Robin2 and AWOL for your great suggestions, the main problem i am facing here is, which weighing controller i use or is there any possibility that Arduino could itself work as a weighing controller, so I don't have to add an additional weighing controller.i am planning to control the motor of the feeder with the analog output of the weighing controller,
I wonder if you mean "weight sensor" rather than "weighing controller"
The Arduino cannot measure weights without a suitable sensor. However if it is connected to a suitable sensor then it could control the measuring process.
And, sorry, I have no suggestions for a suitable sensor.
