10-Digit 7-segment Tube LED Battery Level Display Module for Electronic Bricks
This is a 10-segment LED display module with LED controller chip:MY9221. It can be used as an indicator£¬such as the physical parameters of the battery life£¬ voltage£¬ sound. 10 LED: a red£¬ a yellow£¬ a dark green£¬ and seven green. Different colors corresponding to different strength. Module uses 4pin Grove interfaces£¬ you can easily connect it with Arduino£¬ With some extend sensors£¬ you can make a lot of interesting applications. Input voltage: 3.3V/5V Each LED can be controlled independently.
