LCD Word Clock using Arduino


This Instructable is about making a 16 character by 2 line LCD Word Clock with DST switch.

The pictures show how some of the times will read out.

I have made a few of these for family and friends already and they have been quite well received probably because of their uniqueness. I have even made a few of these for myself which are now in use.

Step 2: Construction

Initial preparations:

If you are interested in building the clock the way I did, then please refer back to my first Instructable to get the bread board power supply ready for the project and to my second Instructable “Kitchen Sink Clock” to get the info needed about working with the Anarduino Kit and programming the ATMEGA328P and the Precision RTC module using the INO file provided with this Instructable.
