ABSTRACT

The human body is a living mechanism. It's the basis that allows us to move, play, work, and participate in all of our activities. A person's capacity to move their bodies is gone when they are paralyzed, and they must rely on others to satisfy their requirements. Since then, a new assistive device called the "Tongue Controlled Wheelchair Using PIC Microcontroller" has been employed to help the patient become more self-sufficient. The tongue controlled wheelchair is a non-invasive research project that looks at how technology might help those who are disabled. This paper describes a project based on a contact sensor called the "Hall Effect sensor" that is placed on the tip of the user's tongue and activated by tongue movement, as well as receiving sensors on the user's cheek bows that determine the wheelchair's motion, apply the command to the motors to function and let the person to travel right, left, forward, and even halt according to his demands.

Key Words: PIC Microcontroller, Hall Effect sensor, Crystal Oscillator, Motor drivers, RF Transmitters, RF Receivers, Decoder, Encoder, DC Motors, Power Supply.
