Developing Word Clock from Photo Frame

Overview

The project uses an old photo frame, Arduino, and a couple of external components to create a word clock.

Details

For each minute in 12-hour cycle, 720 pictures with actual time words are needed to be stored and then every minute, it lets the circuit to hit next button. A simple optocoupler can be used in order to simulate the hitting and pressing of the next button. A processing script can be used to generate 720 images with different words on it. The images are uploaded to the photo frame memory after being generated and start a clock. An SD card is used by the frame to read photos which was formatted into FAT32.

An RBBB Arduino clone was wired up to the forward button to make the clock advance every minute and programmed it to press the button every minute. Each minute is represented by generating an image, to turn it into a clock. The project shows the words written out in English for simplicity but it would be fun to make one that has a different photo background every minute, which shows a really slow animation, or slowly fades between colors.
