Starting a new thread because my last thread went dead :-)
I'm looking into buying an Arduino Uno and Ethernet shield. I wanted an Ethermega but can't find a UK stockist. Only an Australian warehouse with a UK style storefront ;-)
I want my Arduino project to do (amongst a lot of other things, like monitoring inputs) to sound a piezo buzzer on the hour every hour from 1800-2200.
I don't want to adjust for daylight savings time.
I read that I can query an internet time server to obtain the current time. I could do this in my sketch every day at 1500, for example. And on power on.
But what I don't know is if I need a RTC module for this to be useful?
Can anyone advise on how this is practically done?
