Whadda WPI471 Expansion board 2 pc(s)

This module is ideal for displaying battery charging, water tanks etc...!

With the Whadda bar graph module, you can enable a microcontroller board to easily drive a 10-segment blue LED bar graph. The module uses a TM1651 LED driver chip to drive the individual LED segments that can be controlled with only 2 GPIO pins of a microcontroller (such as an Arduino® compatible board). It should be noted that some of the LED segments are wired together, was this results in 8 different controllable states of the LED bar diagram.
