Arduino 7-Segment Display Tutorial for Beginners | Arduino UNO 0–9

🔢 ARDUINO BASICS #07 — 7-SEGMENT DISPLAY How can seven tiny LED segments display numbers from 0 to 9? In this practical Arduino tutorial, we'll connect a 1-digit common-cathode 7-segment display to an Arduino UNO and program it to display numbers from 0 to 9. In this video you'll learn: ✅ What is a 7-segment display? ✅ Seven segments A–G ✅ Common-cathode display ✅ How individual segments work ✅ Why 220Ω current-limiting resistors are used ✅ Complete Arduino UNO wiring ✅ Segment-to-pin connections ✅ Arduino code ✅ Displaying numbers 0–9 ✅ Uploading the program ✅ Testing the display ✅ Basic troubleshooting ✅ Practical applications COMPONENTS USED: • Arduino UNO • 1-digit common-cathode 7-segment display • 7 × 220Ω resistors • Breadboard • Jumper wires PIN CONNECTIONS: A → D2 through 220Ω B → D3 through 220Ω C → D4 through 220Ω D → D5 through 220Ω E → D6 through 220Ω F → D7 through 220Ω G → D8 through 220Ω Common Cathode → GND The program automatically displays numbers from 0 to 9, with each number staying on the display for one second. 📱 Want to understand the complete theory of the 7-segment display?
