The Kimat – LED bar module is originally designed as a
quick I/O state tester. However, the present design also
works as a general purpose display using an 8-segment
LED bar for applications such as battery level indication,
equalizer display or perhaps as a sensor level indicator.
Unique to this module are the input headers. The
headers are arranged for quick connection to any of
your Arduino headers with just one or no wire at all.
There is also an onboard 8-channel DIP switch that
allows the user to enable/disable each LED segment.
This may be useful in cases where not all adjacent pins
are intended to be used with the LED segments (e.g.
some pin are an inputs).
