  • Description

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). It should be noted that some of the LED-segments are wired together, resulting in 8 different controllable states of the LED bar graph.
