Description
The LED 7-segment display is used a lot in DIY projects to display numbers and letters, that is because they are easy to use and they are low in cost. This module only needs two Arduino pins to control the four 7-segment displays. Each of the numbers can be set to act individually or together as an entire display, and if you integrate additional LED Tube Displays they can all act together in a chain or cascade.
