// Capacitive touch Modlue for home automation // 
// Things you require to do this project are Wiz Wiki 7500 board, TTP224 4-way Switch Touch Sensor Capacitive Digital Touch Sensor Module FZ0714,
//few connecting wires
//connections are as follows
// 5V and GND for both the boards
//OUT 1 = D8
//OUT 2 = D7
//OUT 3 = D6
//OUT 4 = D5
// To make it more effective connect a relay controller board and configure some i/o lines instead of LED's in the wiznet board...........
