Desktop Clock with WiFi, no need for a DS1307

WifiDeskClock

Desktop Clock with WiFi for accurate time display!

Introduction

I like clock. Especially digital ones. I made a digital desktop clock already using DS1307 as shown in my other repo:

However there are things that can be made much better.

• DS1307 time drift. After a few months / years, the time is not accurate anymore.
• No time synchronization. During setting time, need to really set it at 00 seconds to be a bit accurate.
• Inability to store timezone information.
• Need to adjust the clock for Summer Time / Winter Time. I ended up +- 1 hour. It is only 2x a year, but still.
• DS1307 is an extra hardware. Extra cabling. Extra ordering. Also CR1032 battery needed.

Having a WiFi clock which is synchronized with NTP server makes the time accuracy high. I don't have to set the +- 1 hour for daylight savings. Also I can select the timezones easily (thanks to the ezTime Library) The only thing I need is a proper internet connection and WiFi signal.

README update

Typo. Missing readme url for the other clock. I suppose you want to point to karamel traktatie?
