With this project the viewer can use an Android device to display the speed and distance travelled by a small vehicle, such as bicycle, go kart or scooter. It features a speed limit setting that can be used to activate a beeper if the speed limit is exceeded. The speedometer logic is all in the Arduino, and the Android app is used for display and configuration. Works with Arduino R3 (Uno, Leonardo, Mega 2560) boards.
