Thanks! I don't think it's possible to use a 2nd matrix as they would both be on the same i2c address. But I might be wrong. You'd be better off using a larger display or use 2 Arduinos. Sounds like a cool project.
Thanks! The DS3231 Real Time Clock has a small battery that keeps time while the Arduino is unpowered.
