Overview
The present invention relates to an android based handheld device preferably Smartphone or tablet with a control system for controlling the speed of DC motor that can be accessed via the Bluetooth. The Bluetooth terminal application and Arduino compiler is used to operate and control the switching action of the D.C motor. An application based on Android is installed in the device which acts as a display panel for the user to send/receive/view the output and input of the DC motor. The present invention provides end to end security using Android which makes it a secure socket along with a PID (proportional-integral-derivative) controller. The system is able to control the D.C motor from a range of Bluetooth device that is 10-12 meters. The system is designed in such a way that it can be integrated with robotics, drones and can be used in smart buildings.
