AUTOMATION IN GRINDER USING MICROCONTROLLER

Abstract : The main objective of the project is to implement the “Automatic grinder” which will do all the process of the normal grinder automatically. Microcontroller is used to control all the process of the grinder. In automatic grinder there is no need of man power, the only work is to drop the rice in the grinder, like washing machine. This machine will automatically give water when grinding and it will stop after the grinding process.

 EXISTING SYSTEM :

 Grinder is playing a vital role in the day to day life. It is normally used to make flour. In normal grinder all the works are done by the human like giving water at the particular time and frequently checking the ripeness of the flour. Man power is needed to make the flour and human have to spend more time with the grinder. The main problem in normal grinder is, it requires human knowledge for the entire process. Human want to monitor the system always, whether the water is sufficient to grind the rice. Cleaning the grinder after making flour is the complex process of the normal grinder.

 DISADVANTAGE :

  Human want to monitor the system always, whether the water is sufficient to grind the rice. Cleaning the grinder after making flour is the complex process of the normal grinder.

 PROPOSED SYSTEM :

 In this project microcontroller is used to control all the process of the grinder. Different timings for the various types of inputs are fixed in the controller.

 ADVANTAGE :

 Step down transformer is used to reduce the voltage from 230V to 12V and 9V Rectifier circuit is used to convert AC to DC. Because each device is operating under DC signals .Rotational motor is used to tilt the drum in forward and reverse direction. Pump is used to pour the water in to the drum and the keypad is used to select the quantity of the ingredients
