Speed control of BLDC motor through mobile application via secured Bluetooth

Speed control of Brushless DC motor has a wide range of applications in today's world. In this paper a technique based on wireless speed control of Brushless DC motor via Bluetooth is proposed. The signal is sent from the android mobile which is connected to the Arduino Uno through Bluetooth module. Pulse Width Modulation (PWM) technique is used to control the speed of the Brushless Direct Current motor (BLDC). The display shows the control commands and responses obtained to get both Clockwise and Anti-clockwise torque.
