ABSTRACT: This prototype uses an Arduino microcontroller to design a myoelectric prosthetic that reads electrical signals from the residual limb and powers motors for motion. The goal is to create a prosthetic limb that can sense muscle movements and automate the motion, making the amputated person feel the bionic limb as their own. This prototype uses low-cost, high-power materials and POT muscle sensor to sense muscle movement. This project presents the design and implementation of a POT Sensor Board Leg Operation System for handicapped individuals. The system is built to assist people with mobility impairments by enabling leg movement control through a potentiometer (POT) sensor. The core components of the system include an Arduino Uno as the microcontroller, a CNC shield for motor control, an L298 motor driver for driving DC motors, and a 12V battery for power supply. The POT sensor is used to capture user inputs, translating rotational motion into electrical signals that are processed by the Arduino Uno. Based on the input, the L298 motor driver actuates the motor, enabling controlled movement of the leg support. The CNC shield helps in integrating the motor driver with the microcontroller, ensuring efficient signal transmission and motor control.
