The object of this project Coffee Maker is to make coffee automatically without human interference. This project is designed with the Microcontroller Mechanical arrangement, solenoid calves and DC Motors.
In this project we are using two tanks in which one tank contains the Milk and another one contain the Coffee Powder. These tanks are opened through a motor arrangement and a solenoid valve and they all controlled by Microcontroller. In microcontroller we have to program for the ration in between the Milk and Coffee Powder and the volume per stroke output. The key pad is connected to the microcontroller. So it we press the key the signals are given to microcontroller so it activates the DC Motor and it will be in on condition up to the set volume. The set volume can be achieved through the time and flow relational equations. This motor is connected to tank valve, so Milk and Coffee Powder are mixed in the ratio as per mentioned. After the set time the microcontroller deactivate driver so the motor is switched OFF. Now we can get the coffee.
This project Coffee Maker is mainly used in the complex shop. It does not require any Man and also we can save time. This project will optionally available with the desired input for ratio calculation, volume and other necessary items. This is a microcontroller based projects so the accuracy and the precision are very high. It is less power consuming part.
