What is 7-Segment display?
A 7-segment display is a form of electronic display device used to represent decimal numbers. It consists of seven individually controllable segments, arranged in a pattern resembling the numeral “8”. Each segment can be selectively turned on or off to form different numerical digits (0-9) or some alphanumeric characters. The segments are typically labeled A through G.
How it works?
ESP32 through its GPIO pins is used to control the individual segments of the 7-segment display enabling the display of different numerical digits. The code specifies which segments to illuminate for each digit, creating a visual representation on the display.
