LED Matrix Clock |

|---|---|---|

| This is my second LED clock. I built it a few years ago out of four 5x7 LED matrices. It's pretty basic, it just tells time in 12 hour format. It doesn't even display AM/PM. Hey, if you can't tell when it's AM or PM, maybe a clock isn't what you need. I just needed a clock you could look at to give you the time right away. Input is through a pushbutton rotary encoder. | ||

| Each digit has its own control board driven by a Pic16f873. The digit modules receive time data from the main control board serialy by UART. This is one of the prototype boards. For the final build, I ordered some PCB's from one of the online PCB fab houses. | ||

| The back of the clock. Nothing fancy here. Just the power plug and the rotary encoder used for setting the clock. | ||
