SMS Based Door Lock Using CLPD and GSM Module


February 28,2014 - April 15,2014

Digital Lab Project, 4th Semester IIT Bombay

This project was a half semester project in Digital Lab. The use of either CPLD's or FPGA's in the project was a necessary. We (I and my lab partner) decided to use the commercially avaliable GSM Modules to make a cheap SMS controlled door lock based on CPLD. Look at the video to see the final outcome, we have not yet put the actual mechanical lock in the system.




Components Used:

  • Krypton CPLD Board
  • SIM900 GSM Module
  • 3.3V-5V Logic Level Convertor
  • Mechnical assembly with rack and pinion
  • L293D Morot Driver
  • Low RPM Motor

Softwares Used:

  • Altera Quartus ii, for writing VHDL code
  • Altera ModelSim for simulation
  • Hyperterminal to observe the transmissited and recieved data.

Basic Working Principle

The basic concept and the motivation behind this project can be found in this final report we made.Also, I would be extremely happy if someone took this project and developed upon it and hence this repository on my github page will help you understand the code.
