This is a project for anyone that wants a nice big clock that's viewable from 12 meters away or up close. You can make it as big as you want. It also incorporates a built in alarm clock that can be used as an event handler, say for a automated watering system for a garden or to remind you about that weekly meet up your meant to go to.

If you like it then please DONATE to my work effort!

Step 1: Step 1: Parts you need

You will need the following parts to construct the Master Clock

- Freetronics DMD display

- Real Time Clock Module for Arduino (Like this one )

- Buzzer (or similar - enough to wake you up in the morning)

- Momentarily On push button

- 2x On-Off buttons (One for power -optional)

- Arduino Uno or similar

- Arduino Uno Proto shield (Optional - If you want things a little neater)

- A 5VDC regulated power supply capable of 4 - 30 Amps (Optional for high brightness - Not needed for normal operation)

<p>Hi friend! First, thanks for Instructable; <br>This code works on a 16x64 Matrix? If not, what needs to be changed? <br>I have a 16x64 matrix and would make this watch; <br>thanks</p>
<p>Nice instructions for this clock. I have most of the items to get started and only need to pick up a few parts. Thanks for the instructable!</p>
