Description
Drive a 10-segment blue LED bar graph, controllable by two GPIO pins
Supply voltage: 3.3 to 5 V DC; color: blue; driver chip: TM1651
Number of LED segments: 10; number of level indicators: 8; interface: two-wire serial
The Bar Graph Display Module (2pcs) is ideal for displaying levels of battery charge, water tanks, and more. It utilizes a TM1651 LED driver chip to control the 10-segment blue LED bar graph with only two GPIO pins of a microcontroller (such as an Arduino compatible board). It is important to note that some of the LED-segments are wired together, resulting in eight different controllable states of the LED bar graph.
