This document is a project report on an automatic packaging machine created by three students for their diploma in mechatronics. The project uses a PIC16F877 microcontroller to control actuators, relays, and sealing machines to automatically weigh and package powder materials based on the weight measured by a load cell. The machine fills cups with material from a hopper, then uses actuators to move the cups under sealing machines that seal and cut the packaged material before repeating the process. The report includes the circuit diagram, design steps, working, program, and photographs of the completed automatic packaging machine.

4. SYNOPSIS
 In this project we shall pack the powder material by
weighting it automatically.
 We are doing this using PIC16F877.
 We are using 5 actuators (A1,A2,A3,A4,A5), 4 relays
(R1,R2,R3,R4) 2 sealing machines (S1,S2), a load cell(l1)
 The material falls from the hopper to a cup like structure,
there, the load cell (L1) detects the weight and sends a
signal to the PIC, the PIC gives an O/P of 5 volts to a relay
R1, which in return actuates the actuator A1.
 The materials from the hopper falls to the cover through the
pipe, the actuators A2, A3, A4 actuates at the same time
through relays R2, R3, R4. So, the sealing machines
connected to the A3, A4 seals the packet and cuts the
packet with the sealing machine heat itself.
 This process repeats again.

5. ACKNOWLEDGEMENT
The satisfaction that accompanies the successful completion of any
task would be incomplete without the mention of the people who have
made it possible, and whose constant guidance and encouragement
served as a boon and made any effort with success.
Our heartfelt thanks to LT. COL. (RETD) V. SUNDARAMURTHY
(Principal of NTTF VTC) for allowing us to pursue our Diploma in
Mechatronics final year MSD project. His words of wisdom and
patience were much more than a blessing.
We would like to express our sincere gratitude to
Mr K. SURENDHAR (SENIOR TRAINING OFFICER), also our special
thanks to him for allowing us to undertake the project work and helped
us by providing useful data and information relevant to complete our
MSD project.
