Abstract:
The main objective of this project is to provide the effective GSM trainer board solution. AS the GSM trainer board is the important requirement of Communication system lab. we have done the experiment on GSM trainer board which needs a dedicated computer system to run its software and then we have to connect the trainer with computer serially and then we send the required operation to our GSM trainer through software run by a dedicated computer and that required operation goes through serial cable connecting both trainer board and a dedicated computer. The available solutions of trainer boards were taking too much cost, space, power so we decided to reduce all these issues by providing the effective learning environment. In our project we used 3.2inches touch screen LCD, Arduino mega 2560 as controller, GSM sim900 module for GSM operation (call, message and phonebook), and PS2 keyboard to input data from user. By using all this hardware the user can perform all GSM operations (making/receiving call, sending/receiving text message, phonebook operations) using AT commands manually (command mode) as well as automatically (graphical mode).
