Monitoring linux server using arduino, ethernet module, LCD and PHP.

1. An Arduino Uno
2. A Linux server with php support (debian/nginx)
3. Ethernet module (ENC28J60)
4. EtherCard Library
5. 16 x 2 LCD screen

1. Download arduino sketch
2. install EtherCard Library
3. Configure the lcd pin connections
4. Configure Ethernet module pin connections

• VCC - 3.3V
• GND - GND
• SCK - Pin 13
• SO - Pin 12
• SI - Pin 11
• CS - Pin 10

5. Upload data.php to your web server
6. update remote server IP address and path to php script in arduino sketch
7. DHCP is enabled by default , You can set static IP for arduino if needed
8. Connect the ethernet cable and upload the sketch to arduino
9. Adjust the HTTP_HEADER_OFFSET value if the readings looks incorrect
10. Use serial monitor for debugging

I have only tested it on my debian/nginx VPS , you may need to adjust the HTTP_HEADER_OFFSET value to remove any unwanted http headers.
