Now the problem is that he had to activate the motors in sequence and decide the magnitude of vibration, for each blending process. Moreover when he wants more than one crystal of exactly same quality, he could not remember the sequence and magnitude of vibration for every time he does the process. Even if he remembered, he could not be so accurate. So he wanted a device with following features,
1. He will teach only once, how to activate the motors (what sequence and what magnitude).
2. Once he asks the machine to replay, it should reproduce what it was taught.
3. He may re teach the machine when he wants to manufacture a different crystal.
Arduino is used to establish the automation. Few buttons are used namely RUN, LEARN, REPLAY and CLEAR. With the LEARN button ON, whatever is taught to the machine will be recorded in the EEPROM. By pressing the CLEAR button, the memory will be cleared. By pressing REPLAY button, the sequence stored in the memory will be replayed.
Test results are furnished below.
The implementation was presented in International Conference on Information Technology, Electronics and Communications and published in the proceedings. Find the paper below.
