This module is ideally suited to display levels of battery charge, water tanks, etc…! The Whadda bar graph module allows any 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, which can be controlled by using only 2 GPIO pins of a microcontroller (such as an Arduino® compatible board).
