Indicators have been long used in cars for turning indication. One usually needs to switch the indicator in a particular direction before taking a turn. Also one is supposed to switch respective indicator before changing lanes on a highway to signal. Another problem is the braking lights, the red braking lights are not visible enough during day.

Well here we design a digital car indicator system that automatically operates the car indicator with a digital display without needing the user to switch anything manually. The system when mounted on a car delivers following advantages:

  • Display Turning Directions using Graphical Display
  • Automatic Turning Direction Sensing Using Sensor
  • Automatic Braking Sensing
  • Display Braking on LED Display
  • Large Display for Night and Daylight Visibility

The system makes use of a Atmega 328 Microcontroller along with an accelerometer gyro sensor, LED display board, buzzer, buttons, basic electronics circuitry and PCB board to develop this system. The system will put forth a next generation automatic direction and braking indicator display system. The system when started constantly monitors tie accelerometer gyro sensor for signals. The sensor gives away directional signals then sensing a directional change and also a change in acceleration is detected on braking.

When the vehicle turns or changes lane, it is sensed by the sensor and this signal is read by the controller. The microcontroller now checks the signal and detects the direction of turning. It now displays arrows pointing to that particular direction on LED display. When the vehicle brakes there is a sudden deceleration in vehicle speed that is detected by the accelerometer sensor. This signal is detected by the controller as it scans the sensor.

The microcontroller now displays stop symbol on the led display to signal braking. So this system can be mounted on backside of a 2 wheeler or a 4 wheeler for automatic turning as well as braking indicator that will be visible even in daylight.
