Hello,
I am involved in a project where we require an Arduino connected directly to a home wifi router, to be able to tell if any users are currently connected to that router.

Basically our goal is to have the Arduino perform simple operations whenever a user connects/disconnects to the home wifi network.

How difficult would this be to achieve for someone with limited programming/electronics experience?
Thanks

That will be difficult.
A router will not contain information about users that log on to a computer that is connected to a network, but only computers/devices that have been connected to the network. A router will have information about the IP addresses that have been provided to those computers/devices and how long these addresses stay valid. Depending on the router it will show (or not show) whether these computers are currently active (e.g. switched on).
IF a computer would be used by a single user only AND is switched on ONLY when user is using it (switched off otherwise), Linux/windows have utilities (like nmap) to display the computers/devices currently active. I don't know about a similar utility on the Arduino.
