Description

Gesture based Home Automation system is advanced method of controlling home appliances using spartan6 FPGA kit and gesture recognition kit. The gesture kit accepts various hand gestures such us, left to right, right to left, top to bottom and bottom to top and send the data to FPGA kit. Finally FPGA control door lock open/close and bulb On/Off through relay.

Tools Required:

Software:	Xilinx ISE 14.7i
Language:	VHDL
Hardware:	• Spartan6 FPGA Project Kit • Gesture recognition kit • Stepper Motor • Bulb with holder

Gesture Recognition Kit

Gesture recognition kit carrying Microchip’s MGC3130 3D gesture recognition controller, brings a new approach to designing intuitive user interfaces. It’s like a touchpad whose input area extends 10cm upwards into space. Users will be able to command an MCU or PC by gesturing with hands and fingers above the board, and by touching and tapping its surface. The board comes with an IDC cable connector. The silkscreen on the back of the board depicts various supported gestures (flicking, drawing circles, airwheels, taps and double taps and so on).

Working Principle 

Gesture recognition kit detects hand gesture from user and process the data using PIC microcontroller. Microcontroller output gesture data at digital output in the digital I/O header.

Spartan6 FPGA project kit is directly receives gesture data through I/O pin and perform control statements.

The control statement includes door open/close control using stepper motor with ULN2003 diver circuit.

Also lights ON/OFF control using Relay interface with CFL Bulb.
All the control operation gets displayed in 2×16 LCD interface.

Control Value	Control Output
00	Relay Off – Light OFF
01	Relay ON – Light ON
10	Door Close – Stepper Motor Clockwise rotation
11	Door Open – Stepper Motor anticlockwise rotation
