Single Digit 7-Segment Display Using ESP32

In this Article, we learn about how to make Single Digit 7-Segment Display Using ESP32.

In the Last post, we learned about how to make ESP32 Cam Face Recognition Door Lock System Projects.

Let’s dive into

Components Require:

1. ESp32 board
2. 7-Segment display (Single Digit)
3. Resistor (220 ohm)
4. Jumper wires
5. Breadboard

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.

Usages:

1. Digital Clocks
2. Temperature Displays
3. Counter and Timer Applications
4. Simple Counters
5. Voltage or Current Indicators
