Arduino Speed Detector on Flash

09/02/2011 Category: Arduino, Detector, Measurement, Microcontroller, Project, Sensor

This speed detector uses two photo resistors paired with laser as a form of trip wire. The Arduino Duemilanove with an ATMEga328 captures the tripping action and calculates the amount of time between when each sensor was tripped. By dividing the distance between two trip wires with difference time value, you will get the SPEED.

Basic Speed Meter Project

Instead using LCD, the project uses flash program to display speed meter. Once the speed has been calculated, Arduino send the data to flash program using serial port and display the speed data.
