SPEED AND DIRECTION CONTROL OF DC MOTOR USING FOUR QUADRANT CHOPPER AND ARDUINO

Abstract

Embedded systems are widely used in modern electronic devices to perform specific tasks efficiently and reliably. These systems combine hardware and software to control different operations in applications such as automation, communication, and transportation. They are designed to perform a dedicated function with limited resources and low power consumption. The proposed system focuses on an autonomous electronic toll gate system that uses GPS and GSM technologies to automate the toll collection process. In this system, the location of the vehicle is identified using GPS. When the vehicle crosses a predefined toll gate location, the system automatically detects it and deducts the required toll amount from the user’s account. After the deduction, a message indicating the toll amount and the remaining balance is sent to the user.The system is controlled by a microcontroller which coordinates all the operations. Additional components such as LCD display, motor drivers, switches, and a regulated power supply are used to support the functioning of the system. The LCD is used to display important messages and system status, while the motor driver helps in controlling motors used in the toll gate mechanism. This automated toll collection system reduces traffic congestion, minimizes waiting time at toll plazas, and eliminates manual toll collection. It provides a faster, more efficient, and reliable method for toll payment and improves the overall transportation management system.
