Microcontroller based wireless turn light indication system for trolley of tractor

Abstract

In the 21st century engineering teaching learning process of interdisciplinary courses like microcontroller and its applications, there is need to avail the state-of-the-art learning techniques to enhance the student understanding, along with advanced electronic instrumentation which has become affordable to be used for routine academic demonstration. This paper discusses the concept of a Microcontroller based wireless turn light indication system for trolley of tractor. This methodology avails the advanced technology; people try to make use of wireless technologies in different role. In this system uses the IR sensor, transmitter, receiver and micro controller. Main heart of the system is RF Module. It has two parts RF transmitter and RF receiver. The IR sensors use to detect steering wheel movement and gives signal to Encoder. HT12E are used for encoding and HT12D used for decoding the data. The 4-bit data is converted via HT12E encoder IC. Assign serial data to RF transmitter. At the Receiver side, receiver receive the serial data and this data is sent to HT12D decoder IC which converts into parallel data. Use a micro controller and relay channel to control the indicator signal. The proposed paper aimed to detect the steering direction by IR sensors and turn on/off the left and right. vehicle indicators based on the position of the steering wheel read. This switching is done wireless, avoiding bulky wiring in the vehicle. Automatic turn signal control protects users from accidents and driving safety.
