Description

This LED bar module from Whadda is ideal for displaying battery charge, water level, etc. Let any microcontroller easily control a 10-segment blue LED bar. The module uses a TM1651 controller chip to control the individual LED segments. Segments can be controlled with only 2 GPIO pins of a microcontroller (e.g. an Arduino-compatible® board). Warning: some LED segments are interconnected so there are 8 different luminance levels.
