Abstract
Examination are conducted through online processes. The job recruitment process and degree entrance examination like JEE, GATE, NEET, etc. will be conducted via online center through a third-party company. So, this chapter, per the authors, proposes a system that uses transducer for getting input as a voice. Later, the voice is converted into text then linked with the benbox software and the chosen file is taken as a command for the writing machine. Arduino Uno R3 is connected with stepper motor driver, metal gear servo, expansion board A4988 driver for writing. The machine uses a gantry to move the writing tip along the X and Y axes. The flexible-nib pen is mounted on a servo motor, which rotates the tip onto the third axis. This machine provides comfortability for blind people to write their exam by using voice command.
