Embedded Systems

hi every one

my self manoj kumar an student of electronics and communication engg. i have made an project on microcontroller that is an electronics lock that can be used to lock any door or gate system. my software and hardware is complete.

some description on this project:

this project include an 4x4 key pad system for locking the door

i controls a dc motor with it which i want to apply on an shop shutter to open/close it.

shutter is already installed so i am unable to make a mechanical system so that i can use the motor to move the shutter up and down which is controlled by an microcontroller.

i just guess that i have to amplify the torque of that motor by using some gear system or by any pulley system. or i have to chnage the mortor used . but i have not knowledge of using these things.

so i need help of yours so that i can complete this project. software and circuit work is over just mechanical work is left.
