In this project, we aim at developing an easy gear shifting mechanism for transmission which will make motor car rider’s gear shifting very easy. It is everyone’s personal wish for effortless functioning of the automobile irrespective of the torque for pickup of the vehicle the human is using, yet the most important structure that every engineer works on is the gear shifting mechanism and looking after the effortless and desired ride on the car. Some simple mechanism is arranged with the pmdc motor and cross slider which will help us to change the gear as per the desired torque. In this gear shifting mechanism, gear shifting is done with the help of two cross slides. During this mechanism, the gear is operated by a servo motor which is controlled by the module feed in the Arduino Uno.
