Real time updating weather warnings displayed

The displays have small DIP switches to set their cable select address – essentially giving them different identities.Set one display’s switch to have CS1 on , and the other to have CS2 on.This clock uses the classic video game Pong to tell the time.The 2 players automatically win and lose so their scores show the hours and minutes.An Arduino runs the main code and a DS1307 clock chip keeps time, even when the power is off. 2 x Sure 2416 LED Matrix You can get these from e Bay for around each.They do a red or green display, and with 3mm or 5mm LEDs.Get a board which is designed for a chip to go on, i.e.one that brings each pin of the chip out to a solder pad you can connect wires to.

Connect the displays together using the ribbon cable.

You can use either connector on the back – they are wired the same.

Use one of the free connectors on either display to connect to the Arduino. For testing purposes I poked jumper wires from the Arduino into the ribbon cable connector.

There are only 4 wires needed between the Arduino and the first LED display. You’ll notice each display has 2 connectors on the back.

These are for daisy chaining multiple units together as we are doing.
