I have a dozen computers that occasionally lock up, requiring a manual restart. Since these computers aren’t at home with me, resetting them is getting to be a real pain!
Shorting the front panel pins of the motherboard for a few seconds is all I really need, and I’ve got a 16 channel relay module that I think will do the trick. I hoped to get the relay module working with a device I’m more familiar using, but it uses 3.3V logic and doesn’t work quite right with the 5V of my relay module.
Rather than convert the logic levels, I believe an arduino mega might be just what I need though I really don’t know much about them. I do know I can pick one up locally at micro center, and I’d have all weekend to work with it which fits perfect in my schedule!
What I am looking to do is ping IP addresses (micro center also has Ethernet shields!) then close the relay for 10 seconds if the IP is unresponsive. Would an arduino mega be able to do this, rather easily? I need to check around 12 ip addresses, as well as controlling 12 of the 16 relays, and I’d like for each address to be checked once every 5 minutes or so, continually.
Any pointers in the right direction would be greatly appreciated! I’m pretty decent with google
