Simple host status monitor that checks if the host is online or offline. Unfortunately I ran out of space in Arduino UNO memory to add automatic mode and notification to email. For reasons of memory, I was forced to also limit the number of hosts to four.
Hosts can be edited via web interface.
I used the following components:
- Arduino UNO,
- Ethernet Shield,
- LCD Keypad Shield 2x16,
- micro SD card.
Additional libraries:
- NettigoKeypad (operating the display keys)
- SdFat (I replaced the standard SD by this library because it took less memory)
- aWOT (web interface)
