    Great little device
    Color:Red
    Pros:
    great device only needs two wires to send data to 4 digit clock numbers. It's bright at the highest setting, enough to be seen in full daylight.
    Cons:
    it's a little complicated with the library and sketches. Instead of a serial write you have to send individual digit info to each letter. Not bad but was hoping for an easier "serial write" device. Might have to experiment with writing my own library.
