My wish is to be able to control a number of relays with an Arduino UNO.
One suggestion might be to be able to control the relays from a web page (preferably both time control and manually be able to switch the relays on / off)
Maybe once a day, correct the clock and date in Arduino UNO from an NTP server.
I found a similar project.: Arduino Ethernet Web Server + SD Card + Jquery to control the relay (but no code)
I have not full control if the hardware below works together.
If the memory in the Arduino UNO will be enough?
Hardware .:
- Arduino UNO
- Ethernet card - HanRun Ethernet shield HR911105A with SD-card (16GB)
- Relay card - Velleman Input/Output Shield Kit for Arduino UNO KA05
Software .:
- WEB server?
- Possibly be able to read the status of the various relays with a PC.
- ON / OFF buttons and a timer for relays. ( webpage / xml- file or... )
- Use of NTP server for time correction.
Have tested the different Arduino shields and they seems to work individually
Is there a similar example to use in my case?
Where to begin?
