Design and implementation of a virtual electronic dart system

In this design, we propose a virtual electronic dart system which contains a microcontroller, tri-axis accelerometer and Bluetooth module. The players only need to hold the virtual electronic dart and swing it in the air. The controller will transmit the space coordinates of the virtual electronic dart to the smartphone that calculates the hit location of the dartboard from the flying path of the projection equation. The results are then displayed in the smartphone´s screen.
