How to Build a 7-Segment LED Display Counter with Arduino
This project demonstrates how to build a simple 0 to 9 counter using an Arduino and a common cathode 7-segment LED display. The display shows numerical digits, and the counter is incremented by pressing a push button. It’s a fun and easy project for beginners to learn about interfacing 7-segment displays with Arduino. Components Required: Arduino Uno 7-Segment Common Cathode Display Push Button Switch 330 Ohm Resistors (7 pieces) Breadboard and Jumper Wires Power Supply (9V Battery or Arduino power adaptor) Understanding the 7-Segment Display The 7-segment display is a simple device made up of eight Light Emitting Diodes (LEDs), which include seven segments to form digits and one segment for the decimal point. The segments light up in different combinations to represent numbers from 0 to 9. In this project, we are using a common cathode 7-segment display, where the cathode pins (pins 3 and 8) are connected to the ground (GND). Each segment of the display corresponds to an LED, and by turning on…
