Description
Bar Graph Display Module (2x) by Whadda
Drives ten-segment blue LED bar graph
Controllable by two GPIO pins
Uses a TM1651 LED driver chip
Supply voltage: 3.3 - 5 V DC
Interface: 2 wire serial
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.
