Digital Speedometer using Arduino Board for Formula Student Cars

Abstract

This paper outlines the design and implementation of Digital speedometer system using Arduino. The Arduino board senses the signals receiving from sensor as an input then do some Arithmetic calculations and showed the results on Liquid crystal display (LCD) as an output in kmph. This article uses a GS101201 speed sensor to measure the speed of one of the cars wheels. The Arduino board receives signals from the sensor and calculates the rpm then converted into a speed, and send this information out to the LCD screen on the dashboard of the car. It is compatible with any kind of wheel, simply changing the radius of the wheel in the program in Arduino IDE software. Particularly it is very useful to monitor the speed of Formula student cars, motors, turbines using this Arduino system.
