The Whadda Bar Graph Display Module (2x) is ideally suited to display levels of battery charge, water tanks, etc. This module allows any microcontroller board to easily drive a 10-segment blue LED bar graph.

It uses a TM1651 LED driver chip to drive the individual LED segments, which can be controlled by using only 2 GPIO pins of a microcontroller (such as an Arduino compatible board).

Note: Some of the LED segments are wired together, resulting in 8 different controllable states of the LED bar graph.
