4 digit display Arduino
Use 4 digit display Arduino to display anything from time, distances, weights, battery level, thermistor values or any other information requiring some sort of basic output to the user.
Just having this 7-segment display at hand allows you to also easily debug your device by displaying values during runtime without requiring a serial port connection.
For the four digit display these pins are shared to the other three digits what separates the are the four common cathode pins. If we control each common cathodes connection.
A seven-segment display is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot matrix displays.
Seven-segment displays are widely used in digital clocks, electronic meters, basic calculators, and other electronic devices that display numerical information
This module is extremely easy to use and flexible.
