---------------------------------------------------------
- Web control relay with Arduino -
---------------------------------------------------------
Ethernet module "ENC28J60" is connected to the Arduino :
VCC - 3.3V Arduino
GND - GND Arduino
SCK - Pin 13 Arduino
SO - Pin 12 Arduino
SI - Pin 11 Arduino
CS - Pin 10 Arduino
The relay is connected to the Arduino so:
VCC - 5V Arduino
In1 - Pin 2 Arduino
In2 - Pin 3 Arduino
...
In7 - Pin 8 Arduino
In8 - Pin 9 Arduino
GND - GND Arduino
