Abstract

The system employs a microprocessor-based control mechanism to enhance functionality and precision, implemented with an Arduino bash, a brushless DC (BLDC) motor, and an electronic speed controller (ESC), which permits very fine control of motor speed by employing pulse width modulation (PWM). So with the introduction of PWM signals, the ESC operates perfectly. This configuration demonstrates efficient PWM-based motor control and provides a workable solution to many control and automation problems. For instance, speed control between an Arduino and a BLDC motor is possible. A user finds it easy to operate with a potentiometer that interfaces with the system to adjust the speed of the motor. By presenting system information, a liquid crystal display (LCD) monitor enhances user participation by providing feedback instantly. The patient self-management unit is powered by a LiPo battery to ensure steady and reliable operation at all times. This configuration does illustrate efficient motor control through the use of PWM but also provides a viable alternative for a range of control and automation systems.
