A BLUETOOTH BASED STEPPER MOTOR CONTROL SYSTEM

Networking technology for the Internet of Things (IOT) is widely used in Wireless systems. Although they can be used to exchange control commands and data between machines, they were initially designed for voice communication systems. In this paper, we present the Blue Steps system which gives a user wireless control over stepper motors. The Blue Steps hardware incorporates a Field Programmable Gate Array (FPGA) coupled to a Bluetooth module and a custom build driver circuit. The FPGA hosts a micro-controller and the control logic for the stepper motors. The Bluetooth module establishes a wireless connection between a mobile device and the micro-controller. Apart from the general systems design, we also conceived the User Interface (UI) software and a driver circuit for the stepper motors
