Logicstart Shield compatibility with 5 V Arduino UNO

Recommended Posts

I'd like to use a LogicStart Shield with a basic 5V Arduino UNO to use for early S/W design of a digital clock for a High School STEM program I am teaching.

We need a 7-Seg display and some switches to set the time, timer, and mode of the clock.

It looks like the slide switches would be fine but will the 7-Segment AN drivers be OK driven by 5V Arduino UNO outputs?  As I recall, some of the individual LEDs have limiting resistors on the DUO so I'll stay away from driving those.
